title: How do I change the font size of ticks of matplotlib.pyplot.colorbar.ColorbarBase?
body: <p>I would like to know how to change the font size of ticks of <code>ColorbarBase</code> of <code>matplotlib</code>. The following lines are a relevant part in my analysis script, in which <code>ColorbarBase</code> is used.</p>
  
  <pre><code>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)
  </code></pre>
  
  <p>I am using <code>matplotlib</code> ver 1.4.3 with Python 2.7 on OS X.</p>
