Matplotlib：我们如何控制图形边框和轴边框相对于图形以及多个轴之间的填充？

Question

Unable to control figure border and axes borders padding with respect to figure and between multiple axes as well using fig.add_axes or plt.subplot_adjust

Code:

import matplotlib.pyplot as plt8

`axs=[] 
fig=plt8.figure(figsize=(6.0,4.0),edgecolor='red',linewidth=10,dpi=100) 
print(fig)   
ax1=fig.add_axes([0.6,1,2.0,1.5])
axs+=[ax1]
ax2=fig.add_axes([3.3,1,2.0,1.5])
axs+=[ax2]`

Description:

This is figsize=(6.0,4.0) As per co-ordinates given by me, I want to have 2 rectangle plots inside the above figure

Gap between the 2 plots is 0.7 and width=2.0 for both plots height=1.5 for both plots left pad with respect to figure is 0.6 right pad is 1.1 top pad is 1.5 bottom pad is 1

But this is not working , can anyone suggest solution code ?

Answer 1

The dimensions you use when calling add_axes() need to be fractions of the figure (see here ).

The tuple required is "(left, bottom, width, height)".

Therefore:

ax1=fig.add_axes([0.6/6.0, 1.0/4.0, 2.0/6.0, 1.5/4.0])
ax2=fig.add_axes([3.3/6.0, 1.0/4.0, 2.0/6.0, 1.5/4.0])

Dividing by 6.0, for left position and width, given that you specify 6.0 as figure width. Dividing by 4.0, for bottom position and height, given you specify 4.0 as your figure height.
