如何在 Matplotlib 中仅绘制表格? [英] How do I plot only a table in Matplotlib?

问题描述

是否可以只用 matplotlib 绘制表格?如果我取消注释该行

plt.bar(index, data[row], bar_width, bottom=y_offset, color=colors[row])

这个例子的

然后您可以根据需要自由调整轴的位置.

Is it possible to draw only a table with matplotlib? If I uncomment the line

plt.bar(index, data[row], bar_width, bottom=y_offset, color=colors[row])

of this example code, the plot is still visible. I want to have a table on top of my (PyQt) window and underneath a plot (with some space in between).

解决方案

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.
