I would like to display a font in Times New Roman in the legend of a matplotlib plot.
I have changed all other tick labels/axis labels/titles to Times New Roman, and have searched the documentation but I can only find how to change the font size in a legend using the prop
argument in pyplot.legend()

我想在一个matplotlib情节的图例中显示一种Times New Roman字体。我已经将所有其他记号标签/轴标签/标题更改为Times New Roman，并搜索了文档，但我只能找到如何使用pyplot.Legend()中的prop参数更改图例中的字体大小。

Of course straight after posting, I found the answer. Solution for anyone else with the same issue:

当然，在发帖后，我立即找到了答案。任何其他有相同问题的人的解决方案：

import matplotlib as mpl  
mpl.rc('font',family='Times New Roman')

This wasn't showing up in google results so I'm going to post it as an answer. The rc parameters for font can be used to set a single default font.

这没有显示在谷歌搜索结果中，所以我会把它作为一个答案发布出来。字体的RC参数可用于设置单个默认字体。

任何其他有相同问题的人的解决方案：

import matplotlib as mpl
mpl.rc('font',family='Times New Roman')

The .rc solution given changes the default font for all drawing.

给定的.rc解决方案会更改所有工程图的默认字体。

Here is a solution for doing this when you don't want to change all the fonts, but just the font properties of the legend of this particular graph (a legend belonging to a particular axis object):

当您不想更改所有字体，而只想更改此特定图形(属于特定轴对象的图例)的图例的字体属性时，以下是一种解决方案：

L = ax.legend()
plt.setp(L.texts, family='Consolas')

This allows you to choose a different font for the legend and the axes. I found this helpful when I needed a monospace font for my legend, but not for the axes -- allowing me to create a neat legend like this:

这允许您为图例和轴选择不同的字体。当我的图例需要等宽字体而不是轴的时候，我发现这很有帮助--允许我创建一个整洁的图例，如下所示：

Note how the title is a different font than the legend - this gives me an alignment of numbers that would otherwise be hard to achieve.

注意标题与图例的字体是如何不同的--这给了我一个数字对齐，否则很难实现。

I think this is the better way.

我认为这是更好的方式。

import matplotlib.font_manager as fm

## your font directory 
font_path = '/Users/frhyme/Library/Fonts/BMDOHYEON_otf.otf'

## font_name 
font_name = fm.FontProperties(fname=font_path).get_name()

plt.legend(prop={'family':font_name, 'size':20})

Here is an example from 2023

以下是2023年的一个例子

plt.legend(
    labels,
    bbox_to_anchor=[1, 0, 0.5, 1],
    prop={'family':'monospace'}
)

prop={'family':'monospace'} - change legend font

bbox_to_anchor=[1, 0, 0.5, 1] - move legend to right upper conner

道具={‘Family’：‘monSpace’}-更改图例字体BBOX_TO_ANCOUNT=[1，0，0.5，1]-将图例移动到右上角
