如何在不干扰文本标签颜色的情况下，将饼图中百分比标签的颜色更改为白色？

Question

如何使用matplotlib将饼图中百分比标签的颜色更改为白色，而不干扰文本标签的颜色？当我编辑 textprops={'size': 'x-large','color':'w'}时，文本颜色将变为白色，与背景形成对比

labels = df01['new_sentiment']
count = df01['count']

cmap = plt.get_cmap('Greys')
colors = list(cmap(np.linspace(0.45, 0.85, len(count))))

fig1, ax1 = plt.subplots()
ax1.pie(count, labels=labels, autopct='%1.1f%%', textprops={'size': 'x-large'}, colors=colors)

ax1.axis('equal')
plt.title('7D-prior-PM_sem_sen', pad=30)
plt.savefig('04_7D-prior-PM_sem_sen.tiff', dpi=300, format='tiff', bbox_inches='tight')

Answer 1

可以按如下方式更改内部标签的颜色：

_,_,m = ax1.pie(count, labels=labels, autopct='%1.1f%%', textprops={'size': 'x-large'}, colors=colors)
[m[i].set_color('white') for i in range(len(m))]
