如何使用matplotlib.pyplot更改表格的字体大小? [英] How to change the table's fontsize with matplotlib.pyplot?

问题描述

我正在用pyplot绘制表格，如下所示:

I'm drawing a table with pyplot like this:

    sub_axes.table(cellText=table_vals,
          colWidths = [0.15, 0.25],
          rowLabels=row_labels,
          loc='right')

我想更改表格内容的字体大小，发现有一个fontsize属性， 请参考表"的定义.

I'd like to change the fontsize of table's content, and found there is a fontsize property, please ref definition of 'table'.

它变成:

    sub_axes.table(cellText=table_vals,
          colWidths = [0.15, 0.25],
          rowLabels=row_labels,
          fontsize=12,
          loc='right')

但是当我执行代码时，出现了错误:

But when I execute the code, I got an error:

TypeError: table() got an unexpected keyword argument 'fontsize'

此属性是否已弃用?以及如何使用pyplot更改表格的字体大小?

Is this property deprecated? And how can I change the fontsize of table with pyplot?

推荐答案

我认为文档正在暗示将要设置的参数(注意fontsize并非其他参数的链接)，或者可能有点此刻令人误解.没有fontsize参数.

I think the documentation is either hinting at a parameter-to-be (notice fontsize is not a link like the other parameters) or perhaps is a bit misleading at the moment. There is no fontsize parameter.

浏览源代码，我找到了Table.set_fontsize方法:

table = sub_axes.table(cellText=table_vals,
                       colWidths = [0.15, 0.25],
                       rowLabels=row_labels,
                       loc='right')
table.set_fontsize(14)
the_table.scale(1.5, 1.5)  # may help

这里是一个字体夸大的例子，目的只是为了显示效果.

Here is an example with a grossly exaggerated fontsize just to show the effect.

import matplotlib.pyplot as plt
# Based on http://stackoverflow.com/a/8531491/190597 (Andrey Sobolev)

fig = plt.figure()
ax = fig.add_subplot(111)
y = [1, 2, 3, 4, 5, 4, 3, 2, 1, 1, 1, 1, 1, 1, 1, 1]    
col_labels = ['col1', 'col2', 'col3']
row_labels = ['row1', 'row2', 'row3']
table_vals = [[11, 12, 13], [21, 22, 23], [31, 32, 33]]

the_table = plt.table(cellText=table_vals,
                      colWidths=[0.1] * 3,
                      rowLabels=row_labels,
                      colLabels=col_labels,
                      loc='center right')
the_table.auto_set_font_size(False)
the_table.set_fontsize(24)
the_table.scale(2, 2)

plt.plot(y)
plt.show()
