Python matplotlib decrease size of colorbar labels

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!

Partial answer: print dir(imax1) will give you information regarding available attributes and functions of imax1.

Aha! Found the answer here:

cbar.ax.tick_params(labelsize=10)

P.S. Upvote that answer and give Paul some love!
