本文介绍了如何将传说从情节中剔除的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一系列 20 个图(不是子图)要在一个图中制作.我希望传说在盒子外面.同时，我不想更改轴，因为图形的大小会减小.请帮助我解决以下问题:

我想将图例框保留在绘图区域之外.(我希望图例位于绘图区域的右侧之外).
有没有我把图例框内的文字字体缩小，让图例框的大小变小.

解决方案

您可以通过指定 FontProperties 的 set_size 来缩小图例文本.
资源:
- - 如 Mateen Ulhaq 所述，fontsize='xx-small' 也工作，无需导入 FontProperties.
```
plt.legend(handles=[p1, p2], title="dGl0bGU=", bbox_to_anchor=(1.05, 1), loc='upper left', fontsize='xx-小')
```
  I have a series of 20 plots (not subplots) to be made in a single figure. I want the legend to be outside of the box. At the same time, I do not want to change the axes, as the size of the figure gets reduced. Kindly help me for the following queries:
  1. I want to keep the legend box outside the plot area. (I want the legend to be outside at the right side of the plot area).
  2. Is there anyway that I reduce the font size of the text inside the legend box, so that the size of the legend box will be small.
  解决方案
  - You can make the legend text smaller by specifying set_size of FontProperties.
  - Resources:
    - Legend guide
    - matplotlib.legend
    - matplotlib.pyplot.legend
    - matplotlib.font_manager
      - set_size(self, size)
      - Valid font size are xx-small, x-small, small, medium, large, x-large, xx-large, larger, smaller, None
    - Real Python: Python Plotting With Matplotlib (Guide)
```
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties

fontP = FontProperties()
fontP.set_size('xx-small')

p1, = plt.plot([1, 2, 3], label='Line 1')
p2, = plt.plot([3, 2, 1], label='Line 2')
plt.legend(handles=[p1, p2], title="dGl0bGU=", bbox_to_anchor=(1.05, 1), loc='upper left', prop=fontP)
```
  - As noted by Mateen Ulhaq, fontsize='xx-small' also works, without importing FontProperties.
```
plt.legend(handles=[p1, p2], title="dGl0bGU=", bbox_to_anchor=(1.05, 1), loc='upper left', fontsize='xx-small')
```
