colorbar and secondary axis label

I would like to have my colorbar range from 0 to 1 and add a label
(Leaf A) exactly like the Leaf B label on the other side of the
y-axis.

I have attached my .png

--------------------------------------------------------------
from pylab import *

#pcolor(n, shading='flat', cmap=cm.gray_r)
contourf(n, cmap=cm.gray_r)

title('Intensity Pattern', size=28)
xlabel('Distance (0.01 cm)', size=18)
ylabel('Leaf B', size=18)
axvline(x=ax/2, color='k', linestyle='--')
colorbar()
savefig('eIntensity')
--------------------------------------------------------------

Thank you,
Bryan
