matplotlib中的文本部分着色 [英] Partial coloring of text in matplotlib

问题描述

matplotlib中是否可以部分指定字符串的颜色?

Is there a way in matplotlib to partially specify the color of a string?

示例:

如何将今天"显示为红色，将是"显示为绿色和阴天".是蓝色的?

How can I show "today" as red, "is" as green and "cloudy." as blue?

谢谢.

推荐答案

我只知道如何非交互地执行此操作，即使这样，也只能使用"PS"后端.

I only know how to do this non-interactively, and even then only with the 'PS' backend.

为此，我将使用Latex设置文本格式.然后，我将包括颜色"包，并根据需要设置颜色.

To do this, I would use Latex to format the text. Then I would include the 'color' package, and set your colors as you wish.

以下是执行此操作的示例:

Here is an example of doing this:

import matplotlib
matplotlib.use('ps')
from matplotlib import rc

rc('text',usetex=True)
rc('text.latex', preamble='\usepackage{color}')
import matplotlib.pyplot as plt

plt.figure()
plt.ylabel(r'\textcolor{red}{Today} '+
           r'\textcolor{green}{is} '+
           r'\textcolor{blue}{cloudy.}')
plt.savefig('test.ps')

这导致(使用ImageMagick从ps转换为png，所以我可以在此处发布):

This results in (converted from ps to png using ImageMagick, so I could post it here):
