python - How do I add two colorbars on the same plot in pyplot (matplotlib)? -

i plot 1 subplot like:

title 1 fig1    fig2    fig3  

with common colorbar these 3 figures (1,2,3).

title2 fig4    fig5    fig6 

with common colorbar these 3 figures (4,5,6).

i haven't found way add 2 different colorbars on same figure described above.

it's bit tricky, can share sets of subplots common colorbar.

i've drawn on few previous anwers might worth reading well:

matplotlib 2 subplots, 1 colorbar

how can create standard colorbar series of plots in python

and of course, documentation matplotlib:

import numpy np import matplotlib.pyplot plt mpl_toolkits.axes_grid1 import imagegrid  # generate random data data_top = np.random.random((3,10,10)) * 5 data_bot = np.random.random((3,20,20)) * 10  fig  = plt.figure()  grid_top = imagegrid(fig, 211, nrows_ncols = (1, 3),                      cbar_location = "right",                                           cbar_mode="single",                      cbar_pad=.2)  grid_bot = imagegrid(fig, 212, nrows_ncols = (1, 3),                      cbar_location = "right",                                           cbar_mode="single",                      cbar_pad=.2)   n in xrange(3):     im1 = grid_top[n].imshow(data_top[n],                              interpolation='nearest', vmin=0, vmax=5)      im2 = grid_bot[n].imshow(data_bot[n], cmap=plt.get_cmap('bone'),                               interpolation='nearest', vmin=0, vmax=10)   grid_top.cbar_axes[0].colorbar(im1) grid_bot.cbar_axes[0].colorbar(im2)  plt.show()
