Bug report

Bug summary

• Using pcolormesh with logarithmic color scale and minor ticks enabled results in a cluttered-looking set of minor ticks, apparently because the linear ticks are not removed, just overplotted with the log scale ones.

Code for reproduction

import numpy
from matplotlib.colors import LogNorm
from matplotlib.pyplot import pcolormesh, colorbar, rcParams
rcParams['xtick.minor.visible']=True
rcParams['ytick.minor.visible']=True
data=numpy.random.random((10,12))*100.0+0.1 
pcolormesh(data,norm=LogNorm())
colorbar()

Actual outcome

Expected outcome

• Expect that the colobar minor ticks would appear logarithmically.
