How do I change the font size of ticks of matplotlib.pyplot.colorbar.ColorbarBase?
Question: I would like to know how to change the font size of ticks of `ColorbarBase` of
`matplotlib`. The following lines are a relevant part in my analysis script,
in which `ColorbarBase` is used.

    
    
    import matplotlib.pyplot as plt
    from matplotlib.colors import LogNorm
    import matplotlib as mpl
    
    axcb = fig.add_axes([0.9, 0.135, 0.02, 0.73])
    
    cb = mpl.colorbar.ColorbarBase(axcb, norm=LogNorm(vmin=7e-5, vmax=1), cmap=plt.cm.CMRmap)
    cb.set_label("Relative Photon Intensity", labelpad=-1, size=14)
    

I am using `matplotlib` ver 1.4.3 with Python 2.7 on OS X.


Answer: You can change the tick size using:

    
    
    font_size = 14 # Adjust as appropriate.
    cb.ax.tick_params(labelsize=font_size)
    

See the
[docs](http://matplotlib.org/api/axes_api.html#matplotlib.axes.Axes.tick_params)
for `ax.tick_params` here for more parameters that can be modified.
