更改 pandas 中Boxplot的面色 [英] Change the facecolor of boxplot in pandas

问题描述

我需要更改使用pandas实用程序功能绘制的箱线图的颜色.我可以使用color参数更改大多数属性，但无法弄清楚如何更改框的facecolor.有人知道该怎么做吗?

I need to change the colors of the boxplot drawn using pandas utility function. I can change most properties using the color argument but can't figure out how to change the facecolor of the box. Someone knows how to do it?

import pandas as pd
import numpy as np
data = np.random.randn(100, 4)
labels = list("ABCD")
df = pd.DataFrame(data, columns=labels)
props = dict(boxes="DarkGreen", whiskers="DarkOrange", medians="DarkBlue", caps="Gray")
df.plot.box(color=props)

推荐答案

虽然我仍然建议在熊猫的绘图界面上使用seaborn和raw matplotlib，但事实证明，您可以将patch_artist=True作为kwarg传递给df.plot.box，会将其作为kwarg传递给df.plot，将作为kwarg传递给matplotlib.Axes.boxplot.

While I still recommend seaborn and raw matplotlib over the plotting interface in pandas, it turns out that you can pass patch_artist=True as a kwarg to df.plot.box, which will pass it as a kwarg to df.plot, which will pass is as a kwarg to matplotlib.Axes.boxplot.

import pandas as pd
import numpy as np
data = np.random.randn(100, 4)
labels = list("ABCD")
df = pd.DataFrame(data, columns=labels)
props = dict(boxes="DarkGreen", whiskers="DarkOrange", medians="DarkBlue", caps="Gray")
df.plot.box(color=props, patch_artist=True)
