Python：平行协调子图中的子图

Question

I saw this example on how to create a parallel coordinate plot: Parallel Coordinates :

This creates a nice Parallel Coordinates figure, but I would like to add this plot to an already existing figure in a subplot (there should be another plot next to it in the same plot).

For the already existing figure, the figure and axes are defined as:

fig = plt.figure(figsize=plt.figaspect(2.))
ax =  fig.add_subplot(1,2,1)

For the Parallel Coordinates, they suggest:

fig, axes = plt.subplots(1, dims-1, sharey=False)

How can I reconcile both initializations of the figure and the ax(es)?

Answer 1

One option is to create all the axes using subplots then just shift the location of the one that you don't want to have wspace=0 as is done for the Parallel Coordinate plots:

import matplotlib.pylab as plt

dims = 4
fig, axes = plt.subplots(1, dims-1 + 1, sharey=False)

plt.subplots_adjust(wspace=0)

ax1 = axes[0]
pos = ax1.get_position()
ax1.set_position(pos.translated(tx = -0.1,ty=0))

I have added 1 to the number of columns creates (leaving it explicitly -1+1) and set wspace=0 which draws all the plots adjacent to one another with no space inbetween. Take the left most axes and get the position which is a Bbox . This is nice as it gives you the ability to translate it by tx=-0.1 separating your existing figure.
