通过matplotlib图例中的标记删除线 [英] Remove line through marker in matplotlib legend

问题描述

我有一个用以下代码生成的matplotlib图:

I have a matplotlib plot generated with the following code:

import matplotlib.pyplot as pyplot

Fig, ax = pyplot.subplots()
for i, (mark, color) in enumerate(zip(
    ['s', 'o', 'D', 'v'], ['r', 'g', 'b', 'purple'])):
    ax.plot(i+1, i+1, color=color,
            marker=mark,
            markerfacecolor='None',
            markeredgecolor=color,
            label=i)

ax.set_xlim(0,5)
ax.set_ylim(0,5)
ax.legend()

以此为生成的图形:

with this as the generated figure:

我不喜欢图例中标记的线条.我该如何摆脱它们?

I don't like the lines through the markers in the legend. How can I get rid of them?

推荐答案

您可以在plot命令中将linestyle="None"指定为关键字参数:

You can specify linestyle="None" as a keyword argument in the plot command:

import matplotlib.pyplot as pyplot

Fig, ax = pyplot.subplots()
for i, (mark, color) in enumerate(zip(
    ['s', 'o', 'D', 'v'], ['r', 'g', 'b', 'purple'])):
    ax.plot(i+1, i+1, color=color,
            marker=mark,
            markerfacecolor='None',
            markeredgecolor=color,
            linestyle = 'None',
            label=`i`)

ax.set_xlim(0,5)
ax.set_ylim(0,5)
ax.legend(numpoints=1)
pyplot.show()

由于您仅绘制单个点，因此除了图例中看不到线属性.

Since you're only plotting single points, you can't see the line attribute except for in the legend.
