[Matplotlib-users] tick locations in new matshow()

[Suresh P. <sto...@ya...>]

The new matshow() seems to like ticks every 4 units (or multiples of 4 
for larger scales) rather than the normal, more desirable every 5 units.

Compare:

import pylab
matrix = pylab.rand(30,30)
pylab.matshow(matrix)
pylab.show()

with

import pylab
matrix = pylab.rand(30,30)
pylab.imshow(matrix)
pylab.show()

Looking at the code right now, but since matshow() calls imshow(), it is 
not obvious to me.  I presume it has something to do with the line

ax  = fig.add_axes([0.15, 0.09, 0.775, 0.775])

in matshow().  Still learning the internals of mpl ...

Also, as mentioned in a previous thread, the new matshow() is missing tick 
marks on the lower x-axis.

Cheers,
Suresh
