Python - How To Change Autopct Text Color To Be White In A Pie Chart?
pie(fbfrac,labels = fblabel,autopct='%1.1f%%',pctdistance=0.8,startangle=90,colors=fbcolor) I have the chart displaying just as I want it, with the exception that the text will st
Solution 1:
From pyplot.pie
documentation:
Return value:
If autopct is not None, return the tuple (patches, texts, autotexts), where patches and texts are as above, and autotexts is a list of Text instances for the numeric labels.
You need to change the color of autotexts
; this is done simply by set_color()
:
_, _, autotexts = pie(fbfrac,labels = fblabel,autopct='%1.1f%%',pctdistance=0.8,startangle=90,colors=fbcolor)
for autotext in autotexts:
autotext.set_color('white')
This yields (with Hogs and Dogs example):
Solution 2:
You can do it in one line using textprops
argument of pyplot.pie
. It's simple:
plt.pie(data, autopct='%1.1f%%', textprops={'color':"w"})
In your case:
pie(fbfrac, labels=fblabel, autopct='%1.1f%%', pctdistance=0.8, startangle=90, colors=fbcolor, textprops={'color':"w"})
An enlightening example can be found here.
Solution 3:
Pie object returns patches, texts, autotexts
. You can loop through the texts
and autotext
and set_color
.
import matplotlib.pyplot as plt
fblabels = 'Frogs', 'Hogs', 'Dogs', 'Logs'
fbfrac = [15, 30, 45, 10]
fbcolor = ["blue", "green", "red", "orange"]
fig, ax = plt.subplots()
patches, texts, autotexts = ax.pie(fbfrac, labels = fblabels, autopct='%1.1f%%',pctdistance=0.8,startangle=90,colors=fbcolor)
[text.set_color('red') for text in texts]
texts[0].set_color('blue')
[autotext.set_color('white') for autotext in autotexts]
plt.show()
Moreover you can change the color for individual label, accessing the list item, e.g: texts[0].set_color('blue')
