Matplotlib 绘制虚线圆圈 [英] Matplotlib Plot Dashed Circles

问题描述

鉴于以下内容:

 将matplotlib.pyplot导入为plt将numpy导入为npx = np.random.randn(60)y = np.random.randn(60)x2 = np.random.randn(60)y2 = np.random.randn(60)plt.scatter(x，y，s = 80，facecolors ='none'，edgecolors ='r')plt.scatter(x2，y2，s = 80，facecolors ='none'，edgecolors ='r')plt.show()

我将如何仅针对 x 2 和 y2 用虚线圆圈绘制相同的数据(其中每个圆圈的轮廓是虚线而不是实线)?

提前致谢！

更新:我知道可以使用

对于该标记大小，我宁愿使用 linestyle =':'.

Given the following:

import matplotlib.pyplot as plt 
import numpy as np 

x = np.random.randn(60) 
y = np.random.randn(60)
x2 = np.random.randn(60)
y2 = np.random.randn(60)

plt.scatter(x, y, s=80, facecolors='none', edgecolors='r')
plt.scatter(x2, y2, s=80, facecolors='none', edgecolors='r')
plt.show()

How would I plot this same data with dashed circles instead (where the outline of each circle is dashed instead of solid) for x 2 and y2 only?

Thanks in advance!

Update: I know this can be done with patches as in here, but I need it to be done via plt.scatter if possible because I will also be plotting another set of circles on the same plot and using patches messed with the chart dimensions (was way too thin).

解决方案

Pass linestyle='--' to scatter.

plt.scatter(x, y, s=80, facecolors='none', edgecolors='r')
plt.scatter(x2, y2, s=80, facecolors='none', edgecolors='r',
            linestyle='--')

For that marker size I would rather use linestyle=':' though.
