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:
plt.ylabel("Today is cloudy.")
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):
