I need your help! I have a plotting code which is the following:
fig = plt.figure() ax1 = fig.add_subplot(111) imax1 = ax1.imshow(data,interpolation = 'nearest', origin = 'lower',cmap=cm.jet)#plot cbar = plt.colorbar(imax1, extend='neither', spacing='proportional', orientation='vertical', shrink=0.7, format="%.0f") cbar.set_label(r"ET [mm/month]", size=10) titlestr = "Evapotranspiration in mm/month" plt.title(titlestr) #plt.xlabel("Longitude") #plt.ylabel("Latitude") imax1.set_clim(0,60) labels = [item.get_text() for item in ax1.get_xticklabels()] for ii in range(np.shape(labels)[0]): labels[ii] = str(grid_lon[75*ii/np.shape(labels)[0]]) ax1.set_xticklabels(labels, rotation = 45, ha='right', size = 10) labels = [item.get_text() for item in ax1.get_yticklabels()] for ii in range(np.shape(labels)[0]): labels[ii] = str(grid_lat[75*ii/np.shape(labels)[0]]) ax1.set_yticklabels(labels, size = 10) pngname = "./out/2d_"+variable+"_"+mm+".png" print "save ", pngname plt.savefig(pngname, dpi=None, facecolor='w', edgecolor='w', orientation='portrait', papertype=None, format=None, transparent=False, bbox_inches=None, pad_inches=0.1) print "plot finished"
I would like to set the label size of the colorbar labels (e.g. 0,10,20,...60) to size of 10 or smaller. This will probably go into the line "imax1.set_clim(0,60). Any ideas? I'd be also interested to print information of the imax1 object to command line. How could I do that? E.g. available attributes and functions of imax1.
I deeply appreciate your help!
Use the matpltolib. pyplot. clim() Function to Set the Range of Colorbar in Matplotlib. The clim() function can be used to control the range of the colorbar by setting the color limits of the plot, which are used for scaling.
Aha! Found the answer here:
cbar.ax.tick_params(labelsize=10)
P.S. Upvote that answer and give Paul some love!
If you are here because you're trying to increase font size, but some numbers disappear because of big size with the above answer, you can do
cbar = plt.colorbar() for t in cbar.ax.get_yticklabels(): t.set_fontsize(20)
