Set Matplotlib colorbar size to match graph
I cannot get the colorbar on imshow graphs like this one to be the same height as the graph, short of using Photoshop after the fact. How do I get the heights to match?
You can do this easily with a matplotlib AxisDivider.
The example from the linked page also works without using subplots:
import matplotlib.pyplot as plt from mpl_toolkits.axes_grid1 import make_axes_locatable import numpy as np plt.figure() ax = plt.gca() im = ax.imshow(np.arange(100).reshape((10,10))) # create an axes on the right side of ax. The width of cax will be 5% # of ax and the padding between cax and ax will be fixed at 0.05 inch. divider = make_axes_locatable(ax) cax = divider.append_axes("right", size="5%", pad=0.05) plt.colorbar(im, cax=cax)
