语法参数如下: matplotlib.pyplot.legend(*args, **kwargs) 常用的几个参数: 1.1 设置图列位置 plt.legend(loc='upper center') 1. 0: ‘best' 1: ‘upper right' 2: ‘upper left' 3: ‘lower left' 4: ‘lower right' 5: ‘right'
The syntax to add a legend to the plot: matplotlib.pyplot.legend(["Title"], ncol=1, loc="upper left", bbox_to_anchor=(1,1)) The parameters used above are described below: title:specify the label you want to add. ncol:represent the number of columns in legend. ...
Matplotlib的legend()函数详解matplotlib的legend()函数是创建和定制图形图例的关键工具，它允许你细致地调整图例的位置、字体、边框和背景等属性。以下是关于legend()函数的一些基础用法和实例。基础语法是：plt.legend(*args, **kwargs)，其中loc参数控制图例的位置，如loc='best'自动选择最佳位置。字体...
When I run some of the python files for generating a plot, the legend was not displayed in the plot. I got the below warning message: /home/JPJ/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/legend.py:633: UserWarning: Legend does not support [<matplotlib.lines.Line2D...
