plot - python: how to set the same colormap for 3 subplots -


i using python draw figure 3 subplots. want set colormap hot each subplot , code like:

fig, axes = plt.subplots(nrows=3, ncols=1, figsize=(20,15)) count = 0 ax in axes.flat:     count += 1     if count == 1:         im = ax.imshow(data_in_array, interpolation='nearest',vmin=0, vmax=150)         ax.set_xticks(range(24))         ax.set_xticklabels(('6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','0','1','2','3','4','5'),fontsize=15)         ax.set_yticks(range(8))         ax.set_yticklabels(('belltown', 'downtown', 'industrial district', 'wallingford', 'university district', 'capitol hill', 'lakecity','ballard'),fontsize=15)         ax.set_title('arriving hours of travel survey',fontsize=15)         plt.hot()      if count == 2:         im = ax.imshow(data_out_array, interpolation='nearest',vmin=0, vmax=150)         ax.set_xticks(range(24))         ax.set_xticklabels(('6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','0','1','2','3','4','5'),fontsize=15)         ax.set_yticks(range(8))         ax.set_yticklabels(('belltown', 'downtown', 'industrial district', 'wallingford', 'university district', 'capitol hill', 'lakecity','ballard'),fontsize=15)         ax.set_title('leaving hours of travel survey',fontsize=15)         plt.hot()      if count == 3:         im = ax.imshow(data_stay_array, interpolation='nearest',vmin=0, vmax=150)         ax.set_xticks(range(24))         ax.set_xticklabels(('6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','0','1','2','3','4','5'),fontsize=15)         ax.set_yticks(range(8))         ax.set_yticklabels(('belltown', 'downtown', 'industrial district', 'wallingford', 'university district', 'capitol hill', 'lakecity','ballard'),fontsize=15)         ax.set_title('stay hours of travel survey',fontsize=15)         plt.hot()      fig.subplots_adjust(right=0.8) cbar_ax = fig.add_axes([0.75, 0.1, 0.03, 0.8]) fig.colorbar(im, cax=cbar_ax) plt.show() 

however, plot like: enter image description here

the first 1 not hot colormap, idea fix that?

when plotting on axes, need set global colorbar before plotting. hence, need have plt.hot() call before first ax.imshow().
