colorbar tick label fontproperties

Community matplotlib-users

Could someone please explain how to change the font properties for a colorbar
tick label, the following causes no error, but it does NOT work:

    ## CREATE COLORBAR
    ## make a copy of the image object
    im2 = copy.copy(im)
    im2.set_cmap(colmap)
    ## create new axis for colorbar.
    cax = plt.axes([l+w+0.03, b, 0.025, h-0.035])
    cb = plt.colorbar(im2, cax)#, format='%3.2g') # draw colorbar
    ## set colorbar label and ticks
    p_cax = mpl.font_manager.FontProperties(size='6')
    clabels = clevs[::10] ##clevs, by 10 steps
    clabels.append(clevs[-1]) ## add the last label
    cb.ax.set_yticks(np.linspace(0,1,len(clabels)))
    cb.ax.set_yticklabels(['%3.2g' % cl for cl in clabels],
                        fontproperties=p_cax)
    cax.set_title('sensitivity\n(%s)' % units,
                      fontproperties=p_cax)

NOTE: It does set the title properties correctly.

John,

The following code works for me (Python 2.5.4, Matplotlib 0.99):

# create and format the colorbar
cbar = pl.colorbar(G, ticks=range(g1,g2+1))
cbar.ax.set_ylabel('Gradient (%)', fontsize=10)
cl = pl.getp(cbar.ax, 'ymajorticklabels')
pl.setp(cl, fontsize=10)
