Such as arbitrary ticks, color... Here are some hints for this from

Here's one way to do it, just by changing the tick labels. There are
other more flexible ways too:
sage: import pylab
sage: pylab.clf()
sage: p = pylab.pcolor(pylab.rand(2,2))
sage: p.axes.get_xticks() # see what ticks are in the plot
array([ 0. , 0.5, 1. , 1.5, 2. ])
sage: _=p.axes.set_xticklabels(['0','1000','2000','3000','4000'])
sage: pylab.savefig('foo.png',dpi=96)
Or if you just want to multiply each tick label by a certain amount:
sage: _=p.axes.set_xticklabels([str(i) for i in 1000*p.axes.get_xticks()])
sage: pylab.savefig('foo.png',dpi=96)
Thanks,
Jason

Yes, I think it would be pretty easy. Note that matplotlib just added
some nice convenience functions for dealing with changing the styles of
ticks too, so we could easy change the colors or weights or whatever as
well.
