unevenly centered subplots in matplotlib in Python?
- by user248237
I am plotting a simple pair of subplots in matplotlib that are for some reason unevenly centered. I plot them as follows:
plt.figure()
# first subplot
s1 = plt.subplot(2, 1, 1)
plt.bar([1, 2, 3], [4, 5, 6])
# second subplot
s2 = plt.subplot(2, 1, 2)
plt.pcolor(rand(5,5))
# add colorbar
plt.colorbar()
# square axes
axes_square(s1)
axes_square(s2)
where axes_square is simply:
def axes_square(plot_handle):
plot_handle.axes.set_aspect(1/plot_handle.axes.get_data_ratio())
The plot I get is attached. The top and bottom plots are unevenly centered. I'd like their yaxis to be aligned and their boxes to be aligned.
If I remove the plt.colorbar() call, the plots become centered. How can I have the plots centered while the colorbar of pcolor is still shown? I want the axes to be centered and have the colorbar be outside of that alignment, either to the left or to the right of the pcolor matrix.
