如何调整图表的表格?表和图 matplotlib python 的更多空间 [英] How to adjust table for a plot? More space for table and graph matplotlib python

问题描述

我想分开或增加我的桌子和我的图表的距离，这样它们就不会重叠.我想将大小增加到右边并将表格放在那里，但我似乎无法使其工作，而且我找不到将表格偏移 1 行的方法.

I want to separate or increase the distance of my table and my graph so they don't layover. I thought of increasing the size to right and put the table there but I can't seem to make it work, and I can't find a way to offset the table by 1 line.

图表

global dataread
global top4
global iV
top4mod = [] #holder for table, combines amplitude and frequency (bin*3.90Hz)


plt.plot(x1, fy1, '-') #plot x-y
plt.axis([0, 500, 0, 1.2]) #range for x-y plot
plt.xlabel('Hz')

columns = ('Frequency','Hz')
rows = ['# %d' % p for p in (1,2,3,4)] #top4
colors = 'C0'
print(len(rows))
print(len(str(top4)))
print(top4)


iV=[d*bins for d in iV]  # convert bins into frequency

i=0;
FirstCol = [4, 3, 2, 1]
while i < 4:
    Table.append([iV[i]] + [top4[i]])#[FirstCol[i]]
    i = i+1

cell_text = []
n_rows = len(Table)
index = np.arange(len(columns)) + 1  #0.3 orginal
bar_width = 0.4

y_offset = np.array([0.0] * len(columns))

for row in range(n_rows):
    #plt.bar(index, Table[row], bar_width, bottom=y_offset, color='C0')  #dont use this
    y_offset = y_offset + Table[row]
    cell_text.append(['%1.1f' % p for p in y_offset])

the_table = plt.table(cellText=Table,rowLabels=rows, colLabels=columns,loc='bottom')
#plt.figure(figsize=(7,8))


# Adjust layout to make room for the table:
plt.subplots_adjust(bottom=0.2) #left=0.2, bottom=0.2


plt.show() #display plot

推荐答案

使用 bbox

您可以使用 bbox 参数设置表格的位置.它期望一个bbox实例或一个四元组值(左，底部，宽度，高度)(位于轴坐标中).例如

Using bbox

You can set the position of the table using the bbox argument. It expects either a bbox instance or a 4-tuple of values (left, bottom, width, height), which are in axes coordinates. E.g.

plt.table(...,  bbox=[0.0,-0.5,1,0.3])

产生一个与轴一样宽的表( left = 0，width = 1 )，但位于轴的下方( bottom = -0.5，height = 0.3 ).

produces a table that is as wide as the axes (left=0, width=1) but positionned below the axes (bottom=-0.5, height=0.3).

import numpy as np
import matplotlib.pyplot as plt

data = np.random.rand(4,2)
columns = ('Frequency','Hz')
rows = ['# %d' % p for p in (1,2,3,4)] 

plt.plot(data[:,0], data[:,1], '-') #plot x-y
plt.axis([0, 1, 0, 1.2]) #range for x-y plot
plt.xlabel('Hz')


the_table = plt.table(cellText=data,rowLabels=rows, colLabels=columns,
                      loc='bottom', bbox=[0.0,-0.45,1,.28])
plt.subplots_adjust(bottom=0.3)
plt.show()

您还可以创建一个轴 (tabax) 来放入表格.然后，您可以将 loc 设置为"center" ，关闭轴的旋转并仅使用很小的subplots_adjust bottom参数.

You can also create an axes (tabax) to put the table into. You would then set the loc to "center", turn the axis spines off and only use a very small subplots_adjust bottom parameter.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.rand(4,2)
columns = ('Frequency','Hz')
rows = ['# %d' % p for p in (1,2,3,4)] 

fig, (ax, tabax) = plt.subplots(nrows=2)

ax.plot(data[:,0], data[:,1], '-') #plot x-y
ax.axis([0, 1, 0, 1.2]) #range for x-y plot
ax.set_xlabel('Hz')

tabax.axis("off")
the_table = tabax.table(cellText=data,rowLabels=rows, colLabels=columns,
                      loc='center')
plt.subplots_adjust(bottom=0.05)
plt.show()
