Introduction {#d7963e277}

Effective data visualization is key to the interpretation and communication of data analysis. Ideally a statistical plot or data graphic should balance functionality, interpretability, and complexity, all without needlessly sacrificing aesthetics. That is to say, the perfect visualization is one which uses as little 'ink' as possible to capture exactly the desired statistical inference in an intuitive and appealing format (

有效的数据可视化是数据分析的解释和沟通的关键。理想情况下,统计图或数据图应平衡功能,可解释性和复杂性,所有这些都不会不必要地牺牲美学。也就是说,完美的可视化是一种尽可能少的"墨水",以直观和吸引人的格式准确捕捉所需的统计推断(). As concerns regarding the need for robust, reproducible data science have grown in recent years, so too have calls for more meaningful approaches to plotting one's data.

A common visualization method of raw datapoints is the barplot (see

原始数据点的常见可视化方法是条形图(参见, left panel) to represent the mean or median of some condition or group via horizontal bars (or lines) and represents uncertainty about the illustrated parameter estimated via 'whisker' errorbars, usually conveying the standard error or 95% confidence interval. This approach has been widely criticized on several counts, including: 1) it is prone to distortion (e.g., by cropping of the Y-axis), 2) it fails to represent the actual data underlying relevant parameter inferences, 3) it often leads to misleading inferences about the magnitudes of statistical differences between conditions (

,左图)通过水平条(或线)表示某些条件或组的平均值或中值,并表示通过'whisker'错误条估计的所示参数的不确定性,通常传达标准误差或95%置信区间。这种方法在几个方面受到广泛批评,包括:1)它容易失真(例如,通过裁剪Y轴),2)它无法代表相关参数推断的实际数据,3)它经常导致关于条件之间统计差异的大小的误导性推论( Weissgerber et al ., 2015 ) and 4) it may obscure differences in distributions (and concurrent violations of distributional assumptions in parametric statistics). These limitations are illustrated in

To remedy these shortcomings, a variety of visualisation approaches have been proposed, illustrated in

为了弥补这些缺点,已经提出了各种可视化方法,如图所示, below. One simple improvement is to overlay individual observations (datapoints) beside the standard bar-plot format, typically with some degree of randomized jitter to improve visibility (

,下面。一个简单的改进是在标准条形图格式旁边叠加单个观察(数据点),通常具有一定程度的随机抖动以提高可见性(). Complementary to this approach, others have advocated for more statistically robust illustrations such as boxplots (

)。对这种方法的补充,其他人则提倡更具统计学性的插图,如箱形图(), which display sample median alongside interquartile range. Dot plots can be used to combine a histogram-like display of distribution with individual data observations (

),显示样本中位数和四分位数范围。点图可用于将类似直方图的分布显示与单个数据观察结合起来(). In many cases, particularly when parametric statistics are used, it is desirable to plot the distribution of observations. This can reveal valuable information about how e.g., some condition may increase the skewness or overall shape of a distribution. In this case, the 'violin plot' (

)。在许多情况下,特别是在使用参数统计时,需要绘制观测的分布。这可以揭示关于例如某些条件可能如何增加分布的偏度或整体形状的有价值信息。在这种情况下,'小提琴情节'() which displays a probability density function of the data mirrored about the uninformative axis is often preferred (

)显示关于无信息轴镜像的数据的概率密度函数通常是优选的(Hintze & Nelson, 1998). With the advent of increasingly flexible and modular plotting tools such as ggplot2 (

Figure 2. Extant approaches to improved data plotting.

A) The simplest improvement is to add jittered raw data points to the standard boxplot and +/- standard error scheme.

)最简单的改进是将抖动的原始数据点添加到标准箱图和+/-标准错误方案中。 B ) Alternatively, dotplots can be used to supplement visualizations of central tendency and error, at the risk of added complexity due to the dependence of such plots on choices such as bin-width and dot size.

)或者,点图可用于补充集中趋势和误差的可视化,由于这些图对诸如箱宽和点尺寸之类的选择的依赖性而存在增加复杂性的风险。 C ) A popular recent alternative is the violin plot coupled with boxplots or similar. However, this needlessly mirrors information about the redundant data axis (here, the x-axis). See

最近流行的另一种选择是小提琴情节与箱形图或类似情节相结合。然而,这不必要地反映了关于冗余数据轴(这里是x轴)的信息。看到 figure2.Rmd {#d7963e399} for code to generate these figures.{#d7963e389}

Indeed, this combined approach is typically desirable as each of these visualization techniques have various trade-offs. Simply plotting raw data can reveal valuable information about individual differences, outliers, and unexpected patterns within the data. However, human observers are notoriously poor^

实际上,这种组合方法通常是期望的,因为这些可视化技术中的每一种都具有各种权衡。简单地绘制原始数据可以揭示有关数据中个体差异,异常值和意外模式的有价值信息。然而,人类观察者是出了名的穷人^^ at estimating statistical moments and distributions from raw data (

^估计原始数据的统计矩和分布(;

;"Guess the Correlation," 2017;

;;

; Zylberberg et al ., 2014 ), and the utility of such plots can be limited when the number of observations is large. In this case the dotplot may be advantageous, as it displays both a histogram of raw data points and the frequency of different binned observations. On the other hand, the interpretation of dotplots depends heavily on the choice of dot-bin and dot-size, and these plots can also become extremely difficult to read when there are many observations. The violin plot in which the probability density function (PDF) of observations are mirrored, combined with overlaid boxplots, have recently become a popular alternative. This provides both an assessment of the data distribution and statistical inference at a glance (SIG) via overlaid boxplots^

当观察数量很大时,可以限制这些图的效用。在这种情况下,点图可能是有利的,因为它显示原始数据点的直方图和不同的分箱观察的频率。另一方面,点图的解释在很大程度上取决于点框和点尺寸的选择,当有许多观察时,这些图也可能变得非常难以阅读。最近,观察到概率密度函数(PDF)的观察结果与叠加的箱形图相结合的小提琴图最近成为一种流行的选择。这通过覆盖的箱线图提供了对数据分布和统计推断的一瞥(SIG)的评估^. However, there is nothing to be gained, statistically speaking, by mirroring the PDF in the violin plot, and therefore they are violating the philosophy of minimising the "data-ink ratio" (

To overcome these issues, we propose the use of the 'raincloud plot' (

为了克服这些问题,我们建议使用'raincloud plot'(Neuroconscience, 2018a), illustrated in

。 raincloud图结合了广泛的可视化建议,类似的前体已被用于各种出版物(例如,, Figure 2.4;

, Figure 2.4;). The plot attempts to address the aforementioned limitations in an intuitive, modular, and statistically robust format. In essence, raincloud plots combine a 'split-half violin' (an un-mirrored PDF plotted against the redundant data axis), raw jittered data points, and a standard visualization of central tendency (i.e., mean or median) and error, such as a boxplot. As such the raincloud plot builds on code elements from multiple developers and scientific programming languages (

)。该图试图以直观,模块化和统计上稳健的格式解决上述限制。本质上,raincloud图表结合了"分半小提琴"(针对冗余数据轴绘制的非镜像PDF),原始抖动数据点以及集中趋势(即平均值或中值)和误差的标准可视化,例如作为箱线图。因此,raincloud图基于来自多个开发人员和科学编程语言的代码元素(Hintze & Nelson, 1998;

The raincloud plot combines an illustration of data distribution (the 'cloud'), with jittered raw data (the 'rain'). This can further be supplemented by adding boxplots or other standard measures of central tendency and error. See

Many previous attempts have been made to produce more robust, intuitive, and transparent plots. Our goal here is not to propose a totally novel invention, but rather to make a powerful visualization strategy freely, easily, and transparently available across commonly used platforms. To this end, similar but distinct plotting strategies include beanplots (

以前的许多尝试都是为了产生更健壮,直观和透明的图。我们的目标不是提出一个完全新颖的发明,而是在常用平台上自由,轻松,透明地提供强大的可视化策略。为此,类似但独特的绘图策略包括豆图(), estimation plots (

),以及许多其他人。我们希望在此提供一个跨平台,开放的科学工具,该工具以这些方法为基础,并为尽可能广泛的受众提供强大而透明的数据绘图。{#d7963e495}

Inference-at-a-glance is supported by adding whatever flavor of data summary measure is optimal for the data at hand; typical examples include overlaid boxplots or other illustrations of central tendency such as mean/median and associated confidence intervals. Depending on the analysis at hand, PDF illustration can also be replaced with more advanced options such as posterior probability densities (i.e., as derived from Bayesian inference) or other parameter estimates (

通过添加任何风格的数据汇总度量对于手头的数据是最佳的,支持推断一目了然;典型的例子包括重叠的箱形图或其他集中趋势的例证,例如平均值/中值和相关的置信区间。根据手头的分析,PDF插图也可以用更高级的选项替换,例如后验概率密度(即,从贝叶斯推断得出)或其他参数估计().{#d7963e523}

).{#d7963e523}

Thus, raincloud plots offer the user maximum utility and flexibility, ensuring that nothing is 'hidden away' and that the reader has all information needed to assess the data, its distribution, and the appropriateness of any reported statistical tests in a visually appealing format. Indeed, as illustrated in

因此,raincloud图为用户提供了最大的实用性和灵活性,确保没有任何东西被"隐藏",并且读者拥有评估数据,其分布以及任何报告的统计测试的适当性所需的所有信息,具有视觉吸引力的格式。的确,如图所示, raincloud plots can reveal information that even a boxplot plus raw data might hide away, such as a bimodal distribution which may not be readily 'eyeballed' from raw data points.{#d7963e533} {#f4}

,raincloud图可以显示即使是一个箱形图加上原始数据也可能隐藏起来的信息,例如双峰分布,这可能不容易从原始数据点"眼球化"。{#d7963e533} {#f4} Raincloud plots: a multi-platform tool for robust data visualization Raincloud图:一个用于强...

Figure 4. Raincloud plots leave little to the imagination.

By replacing the redundantly mirrored probability distribution with a boxplot and raw data-points, the raincloud plot provides the user with information both about individual observations and patterns among them (such as striation or clustering), and overall tendencies in the distribution. As illustrated here, even a boxplot plus raw data may hide bimodality or other crucial facets of the data. See

通过用箱线图和原始数据点替换冗余镜像概率分布,raincloud图为用户提供关于它们之间的个体观察和模式(例如条纹或聚类)以及分布中的总体趋势的信息。如此处所示,即使是箱线图加上原始数据也可能隐藏数据的双峰性或其他关键方面。看到 figure4.ipynb {#d7963e551} for code to generate these figures.{#d7963e549}

This tutorial will walk you through the process of transforming your barplots into rainclouds, and also show you how to customize your rainclouds for various options such as ordinal or repeated measures data. First, we'll run the included "R_rainclouds" script, which will set-up the split-half violin option in ggplot, as well as simulate some data for our figures:{#d7963e620}

本教程将引导您完成将条形图转换为rainclouds的过程,并向您展示如何针对各种选项(如序数或重复测量数据)自定义雨云。首先,我们将运行包含的"R_rainclouds"脚本,该脚本将在ggplot中设置split-half violin选项,并为我们的数字模拟一些数据:{#d7963e620}

source("R_rainclouds.R")
source("summarySE.R")

library(cowplot)
library(readr)
# width and height variables for saved plots
w = 6
h = 3

head(summary_simdat)
##    group   N score_mean score_median       sd       se       ci
## 1 Group1 250   49.45877     42.74587 25.27975 1.598832 3.148958
## 2 Group2 250   51.94353     52.69956 25.06328 1.585141 3.121994

The function gives us two groups of N = 250 observations each; both have similar means and SDs, but group one is drawn from an exponential distribution. Now we'll plot a basic barplot for our simulated data. Note that we're using the 'cowplot' theme ( https://github.com/wilkelab/cowplot ) to produce simple, uncluttered plots - you should set-up your own theme or other customization options as desired:{#d7963e689}

该函数给出了两组N = 250个观察值;两者都有类似的手段和标准差,但第一组是从指数分布中提取的。现在我们将为模拟数据绘制基本条形图。请注意,我们使用'cowplot'主题( https://github.com/wilkelab/cowplot)来生成简单,整洁的图表 - 您应该根据需要设置自己的主题或其他自定义选项:{#d7963e689}

Now we can see the raw data (our 'rain'), and the overlaid probability distribution (the 'cloud'). Let's make it a bit prettier and easier to read by adding some colours. We can also use 'coordinate flip' to rotate the entire plot about the x-axis, transforming our 'little prince plots' into true rainclouds:{#d7963e1075}

现在我们可以看到原始数据(我们的&#39;rain&#39;)和重叠的概率分布(&#39;cloud&#39;)。让我们通过添加一些颜色让它更漂亮,更容易阅读。我们还可以使用"坐标翻转"来围绕x轴旋转整个图,将我们的"小王子图"转换为真正的雨云:{#d7963e1075}

In case you want to change the smoothing kernel used to calculate the PDFs, you can do so by altering the 'adjust' flag for geom_flat_violin. For example, here we've dropped our smoothing to give a much bumpier raincloud:{#d7963e1275}

Now we need to add something to help us easily evaluate any possible differences between our groups or conditions. To achieve this, we'll add some boxplots to complete our raincloud plots. To get the boxplots to line up however we like, we need to set our x-axis to a numeric value, so we can add a fixed offset:{#d7963e1473}

现在我们需要添加一些东西来帮助我们轻松评估我们的团队或条件之间的任何可能的差异。为实现这一目标,我们将添加一些箱图来完成我们的雨云地块。为了让箱图符合我们的喜好,我们需要将x轴设置为数值,这样我们就可以添加一个固定的偏移量:{#d7963e1473}

Now we'll make a few aesthetic tweaks. You may want to turn these on or off depending on your preferences. We'll take the black outline away from the plots by adding the colour = group parameter, and we'll also change colour palettes using the built-in colour brewer tool.{#d7963e1745}

现在我们将进行一些美学调整。您可能需要根据您的喜好打开或关闭它们。我们将通过添加color = group参数从图中取出黑色轮廓,我们还将使用内置的颜色酿酒工具更改调色板。{#d7963e1745}

As another example, we consider some simulated repeated measures data in factorial design, where two groups are measured across three timepoints. To do so, we'll first load in some new data:{#d7963e3336}

作为另一个例子,我们在因子设计中考虑一些模拟的重复测量数据,其中在三个时间点上测量两组。为此,我们将首先加载一些新数据:{#d7963e3336}

        "2", "3"))))

sumrepdat <- summarySE(rep_data, measurevar = "score",

Now, we'll plot our rainclouds with boxplots again, this time adding some dodge so we can better emphasize differences between our factors and factor levels. Note that here we need to nudge the point x-axis as a numeric valuable, as this work around does not currently work for boxplots with multiple factors:{#d7963e3461}

现在,我们将再次绘制带有箱形图的雨云,这次加入一些闪避,这样我们就可以更好地强调我们的因素和因子水平之间的差异。请注意,这里我们需要将点x轴轻推为数值有价值,因为这种解决方法目前不适用于具有多个因素的箱图:{#d7963e3461}

Finally, you may want to add traditional line plots to emphasize factorial interactions and main effects.

This plot can give the reader a first idea of the dataset: which group has a larger mean value, and whether this difference is likely to be significant or not. Only the mean of each group score and the standard deviation is visualized in this plot.{#d7963e4965}

该图可以为读者提供数据集的第一个概念:哪个组具有更大的平均值,以及这种差异是否可能是显着的。在该图中仅显示每组评分的平均值和标准偏差。{#d7963e4965}

To have an idea of the distribution of our dataset we can plot a "cloud", a smoothed version of the histogram:{#d7963e4968}

This gives a good idea of the distribution of the data points, but the median and the quartiles are not obvious, making it hard to determine statistical differences at a glance. Hence, we add an "empty" boxplot to show median, quartiles and outliers:{#d7963e5502}

这样可以很好地了解数据点的分布,但中位数和四分位数并不明显,因此很难一目了然地确定统计差异。因此,我们添加一个"空"箱图,以显示中位数,四分位数和异常值:{#d7963e5502}

For some data, you may want to flip the orientation of the raincloud to a 'petit prince' plot. You can do this with the 'orient' flag in the pt.RainCloud Function:{#d7963e6588}

对于某些数据,您可能希望将raincloud的方向翻转为"小王子"情节。您可以使用pt.RainCloud函数中的&#39;orient&#39;标志执行此操作:{#d7963e6588}

You can also change the smoothing kernel used to generate the probability distribution function of the data. To do this, you adjust the sigma parameter:{#d7963e6723}

您还可以更改用于生成数据的概率分布函数的平滑内核。为此,您需要调整sigma参数:{#d7963e6723}

Finally, using the pointplot flag you can add a line connecting group mean values. This can be useful for more complex datasets, for example repeated measures or factorial data. Below we illustrate a few different approaches to plotting such data using rainclouds, by changing the hue, opacity, or dodge element of the individual plots:{#d7963e6846}

最后,使用pointplot标志,您可以添加连接组平均值的线。这对于更复杂的数据集非常有用,例如重复测量或因子数据。下面我们通过改变单个图的色调,不透明度或闪避元素来说明使用raincloud绘制此类数据的几种不同方法:{#d7963e6846}

#adding a red line connecting the groups' mean value (useful for longitudinal data)

Another flexible option is to use Facet Grids to separate different groups or factor levels, illustrated below:{#d7963e6985}

另一个灵活的选择是使用Facet Grids来分隔不同的组或因子级别,如下所示:{#d7963e6985}

As an alternative, it is possible to use the hue input for plotting different sub-groups directly over one another, facilitating their comparison:{#d7963e7075}

To improve the readability of this plot, we adjust the alpha-level using the associated flag (0--1 alpha intensity):{#d7963e7222}

为了提高此图的可读性,我们使用相关标志(0--1 alpha强度)调整alpha级别:{#d7963e7222}

# Setting alpha level
ax=pt.RainCloud(x = dx, y = dy, hue = dhue, data = df,
      palette = pal, bw = sigma, width_viol = .7, figsize = (12,5),

Rather than letting the two boxplots obscure one another, we can set the dodge flag to true, adding interpretability:{#d7963e7324}

我们可以将闪避标志设置为true,而不是让两个箱图彼此模糊,增加可解释性:{#d7963e7324}

#The Dodge Flag

Finally, we may want to add a traditional line-plot to our graph to aid in the detection of factorial main effects and interactions. As an example, we've plotted the mean within each boxplot:{#d7963e7426}

最后,我们可能想在图表中添加传统的线图,以帮助检测因子主效应和相互作用。例如,我们在每个箱线图中绘制了均值:{#d7963e7426}

#same, with dodging and line
ax=pt.RainCloud(x = dx, y = dy, hue = dhue, data = df,
     palette = pal, bw = sigma, width_viol = .7,figsize = (12,5),

Here is the same plot, but now with the individual observations moved below the boxplots again using the 'move' parameter:{#d7963e7538}

这是相同的情节,但现在使用&#39;move&#39;参数将个别观察结果再次移到箱形图下方:{#d7963e7538}

As our last example, we'll consider a complex repeated measures design with two groups and three timepoints. The goal is to illustrate our complex interactions and main-effects, while preserving the transparent nature of the raincloud plot:{#d7963e7659}

作为我们的最后一个例子,我们将考虑一个具有两组和三个时间点的复杂重复测量设计。目标是说明我们复杂的相互作用和主效应,同时保留raincloud情节的透明性:{#d7963e7659}

# Load in the repeated data
df_rep = pd.read_csv ("repeated_measures_data.csv", sep= ",",
        header = None)
df_rep.columns = ["score",  "timepoint", "group"]

# Plot the repeated measures data
dx = "group"; dy="score"; dhue="timepoint"
ort="h"; pal="Set2"; sigma = .2

ax=pt.RainCloud(x = dx, y = dy, hue = dhue, data = df_rep,

      orient = ort , alpha = .65, dodge = True, pointplot = True,

The function is flexible enough that you can flip the ordering of the factors around simply by changing which variable informs the hue parameter:{#d7963e7887}

该函数非常灵活,您可以通过更改哪个变量通知hue参数来翻转因子的顺序:{#d7963e7887}

That's it! Hopefully this tutorial has given you an idea of some of the different ways you can produce raincloud plots in Python. Next, we'll describe how to produce these plots in Matlab.{#d7963e8047} {#d7963e8051}

而已!希望本教程能让您了解在Python中生成raincloud图的一些不同方法。接下来,我们将描述如何在Matlab中生成这些图。{#d7963e8047} {#d7963e8051}

How to Make it Rain in Matlab

Matlab(Mathworks Inc.)是一种专有的数学编程语言,广泛应用于工程,物理科学和神经科学。可以在以下位置找到本教程的代码:{#d7963e8056}

Here you can also find functions to create raincloud-plots (

在这里你还可以找到创建raincloud-plot的功能( raincloud_plot.m and rm_raincloud.m {#d7963e8065}), as well as a "live notebook" (

{#d7963e8065}),以及"现场笔记本"( raincloud_plots_tutorial.mlx {#d7963e8068}) which walks the user through the customization of various raincloud plots.{#d7963e8063}

{#d7963e8068})引导用户完成各种raincloud情节的定制。{#d7963e8063}

First, we'll set up our path and use the colorbrewer function to define some nice colour palettes:{#d7963e8072}

首先,我们将设置路径并使用colorbrewer函数定义一些漂亮的调色板:{#d7963e8072}

% set up a dynamic path
% script must be run from parent directory containing all three tutorial
% directories (i.e., the one 'above' the directory 'tutorial_matlab')

pardir = pwd;
figdir = fullfile(pardir, 'figs', 'tutorial_matlab');
if ~exist('figdir', 'dir')
     mkdir(figdir);
end

% make sure functions to generate plots are on the path
codedir = fullfile(pardir, 'tutorial_matlab');
addpath(codedir);

try
     % get nice colours from colorbrewer
     % (https://uk.mathworks.com/matlabcentral/fileexchange/34087-cbrewer---colorbrewer-schemes-for-matlab)
     [cb] = cbrewer('qual', 'Set3', 12, 'pchip');
catch
     % if you don't have colorbrewer, accept these far more boring colours
     cb = [0.5 0.8 0.9; 1 1 0.7; 0.7 0.8 0.9; 0.8 0.5 0.4; 0.5 0.7 0.8; 1 0.8 0.5; 0.7 1 0.4; 1 0.7 1; 0.6 0.6 0.6; 0.7 0.5 0.7; 0.8 0.9 0.8; 1 1 0.4];
end

cl(1, :) = cb(4, :);
cl(2, :) = cb(1, :);

fig_position = [200 200 600 400]; % coordinates for figures

Now we'll generate some datapoints with similar means and standard deviations; the first is drawn from a random normal distribution and the second from a random exponential distribution. We'll plot these same data repeatedly in different ways further down:{#d7963e8188}

现在我们将生成一些具有类似方法和标准偏差的数据点;第一个是从随机正态分布中提取的,第二个是从随机指数分布中提取的。我们将以不同的方式重复绘制这些相同的数据:{#d7963e8188}

n = 250;

% set a random number generator seed for reproducible results
rng(123)

d{1} = [exprnd(5, 1, n) + 15]';
d{2} = [(randn(1, n) *5) + 20]';

means = cellfun(@mean, d);
variances = cellfun(@std, d);

Let's create a quick bar graph of these data. This is the kind of standard visualization you see in many papers, depicting the mean of the data plus standard deviation:{#d7963e8254}

让我们创建这些数据的快速条形图。这是您在许多论文中看到的标准可视化,描述了数据的平均值加上标准偏差:{#d7963e8254}

f1 = figure('Position',fig_position); hold on;
h = bar(means, 'FaceColor', 'flat', 'LineWidth',.9);

h(1).CData(1, :) = cl(1, :);
h(1).CData(2, :) = cl(2, :);

e = errorbar(1:2, means, variances, '.k', 'LineWidth',.9);
set(gca, 'XTick', 1:2)
title('Bar Plot');

% save
print(f1, fullfile(figdir, '1bar.png'), '-dpng');

As you can see, this tells you something about the data, but a lot of really useful and important information is hidden such as the 'shape' or distribution of the data and the raw observations themselves. A histogram nicely shows some of what we're missing:{#d7963e8378}

正如您所看到的,这会告诉您有关数据的信息,但会隐藏许多非常有用且重要的信息,例如数据的"形状"或分布以及原始观察本身。直方图很好地展示了我们遗漏的一些内容:{#d7963e8378}

f2 = figure('Position', fig_position);
subplot(1, 2, 1)
[n1, x1] = hist(d{1}, 30);
bar(x1, n1, 'FaceColor', cl(1,:), 'EdgeColor', 'k');
title('Histogram') 
subplot(1, 2, 2)
[n2, x2] = hist(d{2}, 30);

However, now we've lost the summary data. The raincloud plot tries to bring these elements together in one intuitive plot. You can use the 'raincloud_plot.m' function accompanying this tutorial to produce these plots in Matlab:{#d7963e8505}

但是,现在我们丢失了摘要数据。 raincloud图试图在一个直观的图中将这些元素组合在一起。您可以使用本教程附带的"raincloud_plot.m"函数在Matlab中生成这些图:{#d7963e8505}

This gives us the distribution (probability density plot), summary data (box plot), and raw observations all in one place. Now we'll walk you through some of the options of the function, which you can use to change various aesthetic properties of the plot. The function only requires a vector of the data you want to plot as the input. Additionally, there are a variety of optional flags you can call to turn the boxplots on and off, to alter ('dodge') the position of the boxes and dots, and to change various aesthetics such as linewidth, colors, and so on. For example, by setting a few different flags we can create more colorful plots:{#d7963e8661}

这给了我们在一个地方的分布(概率密度图),摘要数据(箱形图)和原始观测。现在我们将向您介绍该功能的一些选项,您可以使用这些选项来更改绘图的各种美学属性。该功能仅需要您要绘制的数据矢量作为输入。此外,您可以调用多种可选标记来打开和关闭箱形图,改变("闪避")盒子和点的位置,以及改变各种美学,如线宽,颜色等。例如,通过设置几个不同的标志,我们可以创建更多彩色图:{#d7963e8661}

Here, we'll use the dot and box dodge options to create an overlapping set of raincloud plots, useful for group comparison. The function can be called repeatedly (e.g., from within a loop) - each iteration will overlay the previous. Note that here we're using the 'alpha' parameter to make the plot area see-through:{#d7963e9260}

在这里,我们将使用点和框闪避选项来创建一组重叠的raincloud图,这对于组比较非常有用。可以重复调用该函数(例如,从循环内) - 每次迭代将覆盖前一个。请注意,我们在这里使用&#39;alpha&#39;参数使绘图区域透明:{#d7963e9260}

而已!现在,您应该准备好为各种不同的目的自定义Raincloud图。我们的跨平台教程到此结束!{#d7963e10086}

Discussion {#d7963e10093}

We hope that our tutorials demonstrate the flexibility of raincloud plots for visualizing data. Raincloud plots build on a rich tradition of data graphics, enabling the user to visualize key parameters for statistical inference in a transparent an aesthetically appealing fashion. In this sense, Rainclouds are part of a wider family of plotting tools such as beeswarms (

我们希望我们的教程能够展示用于可视化数据的raincloud图的灵活性。 Raincloud图基于丰富的数据图形传统,使用户能够以透明和美观的方式可视化统计推断的关键参数。从这个意义上说,Rainclouds是更广泛的绘图工具家族的一部分,如beeswarms(), strip plots (

), strip plots (), and estimation plots (

)和估算图().{#d7963e10096}

).{#d7963e10096}

Indeed, our goal is not to argue for the superiority or novelty of raincloud plots over these and other complementary methods. Our focus is on providing a robust cross-platform tool for creating transparent plots. In general, the modularity of the raincloud plot is a strength, and we encourage the user to think carefully about the choice of individual elements (clouds, rain, & confidence intervals) depending on the particularities of their data.{#d7963e10111}

实际上,我们的目标不是争论雨云的优势或新颖性超过这些和其他补充方法。我们的重点是提供一个强大的跨平台工具来创建透明图。一般来说,raincloud图的模块性是一种优势,我们鼓励用户根据数据的特殊性仔细考虑单个元素(云,雨和置信区间)的选择。{#d7963e10111}

It is worth mentioning that here we envision these three aspects of the raincloud plots as sub-serving particular statistical goals. In our examples, the probability distributions depicted by the split-half violin plot ('clouds') illustrate the sample variance. As such they are excellent tools for assessing how data are distributed and checking assumptions (i.e., violations of normality). Considering this, we caution against the use of clouds in this form for statistical inference at a glance, which is better served by comparing some parameter estimates in relation to their uncertainty. Users who wish to use probability distributions for inference should instead consider a more suitable approach such as estimation plots, or by plotting a smoothed histogram of bootstrapped parameter estimates, or simply by plotting rainclouds with boxplots and/or confidence intervals, as we have done in our tutorial examples. The code provided with this tutorial makes it easy to implement whatever histogram function best suits the needs of the user, simply by substituting the PDF estimation function.{#d7963e10114}

值得一提的是,在这里我们设想雨云图的这三个方面作为子服务的特定统计目标。在我们的例子中,分半小提琴图(&#39;云&#39;)描绘的概率分布说明了样本方差。因此,它们是评估数据分布方式和检查假设(即违反正常性)的极好工具。考虑到这一点,我们提醒不要使用这种形式的云进行统计推断一目了然,通过比较一些与其不确定性相关的参数估计值可以更好地实现。希望使用概率分布进行推理的用户应该考虑更合适的方法,例如估计图,或者绘制自举参数估计的平滑直方图,或者简单地通过绘制具有箱线图和/或置信区间的雨云,如我们所做的那样我们的教程示例。本教程提供的代码可以轻松实现最适合用户需求的直方图函数,只需替换PDF估算函数即可。{#d7963e10114}

Additionally, at first glance it may seem redundant to plot both raw datapoints ('rain') and data distributions ('clouds'). However, we put forth that plotting both offers several advantages. First, plotting raw datapoints can enable the automated (i.e., machine-readable) recovery of data from plots even when the data underlying the plot has been lost. Second, plotting raw data can facilitate the identification of unexpected patterns within the data, such as ordinality or outliers, which may not be readily apparent from a probability distribution or box-plot alone. As such we recommend the combination of raw data plots and smoothed distributions (however estimated) wherever possible.{#d7963e10117}

此外,乍一看,绘制原始数据点(&#39;rain&#39;)和数据分布(&#39;clouds&#39;)似乎是多余的。但是,我们提出绘制两者都有几个优点。首先,绘制原始数据点可以实现从图中自动(即机器可读)恢复数据,即使图中的数据已经丢失。其次,绘制原始数据可以有助于识别数据中的意外模式,例如常数或异常值,这些可能不仅仅从概率分布或箱形图中显而易见。因此,我们建议尽可能将原始数据图和平滑分布(无论如何估算)组合在一起。{#d7963e10117}

Preprints, Pull Requests and the value of community science

This manuscript was originally published as a preprint on the Peerj platform ( https://doi.org/10.7287/peerj.preprints.27137v1 ). The eight months since have illustrated the remarkable potential of new publishing infrastructure and landscape make the process of publishing scientific content faster, better and more collaboratively. We here outline just a few of the positives from doing so, and hope this may serve to encourage others. Firstly, posting the manuscript as preprint has vastly widened the reach. To date (March 2019) our preprint was viewed 9803 times, with 6309 downloads. However, views and downloads alone don't necessarily entail engagement. Since publication the preprint alone has already been cited 18 times. Moreover, in depth engagement has gone well beyond mere citations. Several individuals have created their own useful tutorials,

该手稿最初作为Peerj平台上的预印本出版( https://doi.org/10.7287/peerj.preprints.27137v1)。此后的八个月表明,新出版基础设施和景观的巨大潜力使得科学内容的发布过程更快,更好,更具协作性。我们在此仅概述了这样做的一些积极因素,并希望这可能有助于鼓励其他人。首先,将稿件作为预印发布已大大扩大了范围。到目前为止(2019年3月),我们的预印本被观看了9803次,下载次数为6309次。但是,仅视图和下载并不一定需要参与。自出版以来,单独的预印已被引用18次。此外,深度参与已远远超出了引用范围。有几个人创建了自己的有用教程, summarizing our paper {#d7963e10149} and asking useful questions, posted

{#d7963e10177}关于例如超级预测。我们的 codebase {#d7963e10181} itself received feedback through various avenues including formal pull requests on github, comments on the preprint, twitter replies and email.

{#d7963e10181}本身通过各种途径收到反馈,包括github上的正式拉取请求,预印本评论,Twitter回复和电子邮件。在我们论文的这个新版本中,我们尽力整合所有这些建议和评论,这些建议和评论一定会提高我们代码的可用性。{#d7963e10146}

Social media, specifically twitter, provided the central hub where all these benefits coalesced. The paper has been tweeted at least 750 times, with an estimated reach of up to

社交媒体,特别是推特,提供了所有这些好处合并的中心枢纽。这篇论文至少被推文发送过750次,估计达到最多 1,500,000 total followers {#d7963e10187}, and as such is the principal driver for the engagement our preprint has received. This engagement has yielded invaluable feedback, comments, and suggestions, and were even lucky enough to track down the first instance of an early precursor of the raincloud plot (Ellison, 2018). Moreover, the paper itself was inspired by a twitter discussion, and brings together co-authors who have never met in person. Together, these interactions illustrate the fundamentally two-way street of new publishing models, which facilitate access without paywalls and allow for near instantaneous improvements to ongoing work.{#d7963e10185}

{#d7963e10187},因此是我们预印本收到的参与的主要驱动因素。这种参与已经产生了宝贵的反馈,评论和建议,甚至幸运地追踪了雨云阴谋早期前兆的第一个例子(Ellison,2018)。此外,论文本身受到推特讨论的启发,汇集了从未见过的共同作者。这些互动共同展示了新出版模式的根本双向道路,这种模式有助于在没有付费墙的情况下进行访问,并允许对正在进行的工作进行近乎即时的改进。{#d7963e10185}

Conclusion {#d7963e10195}

The future of data science lies in reproducible, robust methods that communicate our results to as wide of an audience as possible. We hope that raincloud plots will help you to better understand and communicate your own data-analysis. In the present paper, we've outlined some of the strengths of these plots compared to traditional methods such as bar or violin-plots. Using the attached code and tutorials, this paper opens up the raincloud plot to a wide variety of scientists in a multitude of disciplines.{#d7963e10198}

数据科学的未来在于可重复,强大的方法,可以将我们的结果传达给尽可能广泛的受众。我们希望raincloud图可以帮助您更好地理解和传达您自己的数据分析。在本文中,我们已经概述了与传统方法(如条形或小提琴图)相比,这些图的一些优势。使用附带的代码和教程,本文为众多学科中的各种科学家打开了raincloud图。{#d7963e10198}
