我想在图例中围绕线条遮挡,如下图所示。
我尝试使用'hatch',如下所示:
handles, labels = ax0.get_legend_handles_labels()
handles[0] = mpatches.Patch(facecolor='red', edgecolor='red', alpha=1.0, linewidth=0, label="Theory (MLL)", hatch='-')
handles[i].set_facecolor('pink')
first_legend = ax0.legend(handles, labels, loc=0, frameon=0, borderpad=0.1)
ax = ax0.add_artist(first_legend)
但这会导致矩形有多行,如下所示:
答案 0 :(得分:5)
您可以将两个句柄放在一个元组中,将它们叠加在一起(请参阅本指南中有关HandlerTuple的内容:http://matplotlib.org/users/legend_guide.html)。除此之外,要使行延伸到修补程序的边缘,您可以使用marker_pad = 0
的普通行处理程序的自定义版本。
from matplotlib import pyplot as plt
import matplotlib.patches as mpatches
from matplotlib.legend_handler import HandlerLine2D
import numpy as np
line, = plt.plot(range(10), color = 'red')
patch = mpatches.Patch(facecolor='pink', alpha=1.0, linewidth=0)
plt.legend([(patch, line)], ["Theory"], handler_map = {line : HandlerLine2D(marker_pad = 0)} )
plt.show()
