关于 Matplotlib 饼状图代码的问题，谢谢大家！

[jacksonvillor]

import numpy as np import matplotlib.pyplot as plt fig, ax = plt.subplots(figsize=(13,8), subplot_kw=dict(aspect="equal"))

recipe = ["USA:99 (44.39%)", "UK:28 (12.56%)", "Germany:33 (14.80%)", "France:15 (6.726%)", "FRG:4 (1.794%)", "Switzerland:6 (2.691%)", "Sweden:8 (3.587%)", "Others:30 (13.45%)"] ingredients=['USA','UK','Germany','France','FRG','Switzerland','Sweden','Others']

data = [99, 28, 33, 15, 4, 6,8,30] colors=['#1F77B4','#FF7F0E','#2CA02C','yellow','#D62728','lawngreen','#8C564B','cyan'] wedges, texts = ax.pie(data, wedgeprops=dict(width=0.5), startangle=30,colors=colors)

bbox_props = dict(boxstyle="square,pad=0.3", fc="w", ec="k", lw=0.72) kw = dict(xycoords='data', textcoords='data', arrowprops=dict(arrowstyle="-"), bbox=bbox_props, zorder=0, va="center")

for i, p in enumerate(wedges): ang = (p.theta2 - p.theta1)/2. + p.theta1 y = np.sin(np.deg2rad(ang)) x = np.cos(np.deg2rad(ang)) horizontalalignment = {-1: "right", 1: "left"}[int(np.sign(x))] connectionstyle = "angle,angleA=0,angleB={}".format(ang) kw["arrowprops"].update({"connectionstyle": connectionstyle}) ax.annotate(recipe[i], xy=(x, y), xytext=(1.35np.sign(x), 1.4y), horizontalalignment=horizontalalignment, **kw)

ax.legend(wedges, ingredients, bbox_to_anchor=(1, 0, 0.5, 1)) plt.show()

代码如上，现在只想让注释框中的国家（英文）放在各自框的上面并居中，数字仍保留在框里，不知道如何修改代码？请大家指导！谢谢大家！（先发帖，一会上图，还不会贴图--~

这是饼状图的图片

既然都在右上角给了图例，我觉得直接去掉国家名也可以:dog:。

@Takamine 谢谢你！目前在撰写论文，因为打印出来是黑白的，所以考虑这个因素，添加上国家名称。

@jacksonvillor 这样阿，我觉得可以图片二次加工一下（ ps ）就好啦 23333。
或者我觉得你可以拿这个调一下参数，换一下参数位置避免遮挡之后的效果可能比你那个好看一丢丢。

@jacksonvillor 可以考虑给每个区域加不同的纹路，matplotlib 里面叫 hatch。
随手 Google 了一下 https://stackoverflow.com/questions/14279344/how-can-i-add-textures-to-my-bars-and-wedges
