Hello list -
I am trying to change the yticks on my colorbar (in combination with contourf)
and cannot figure
out how to do it.
Short example:
x,y = meshgrid(linspace(0,10),linspace(0,10))
a = contourf(x,y,x,linspace(0,10,6))
b = colorbar(a)
This gives a nice colorbar, with ticks at 0,2,4,6,8,10
But I want labels only at 0,5,10. So I thought I can change that as:
b.ax.set_yticks([0,5,10])
draw()
But this gives really wacky results (totally messes up the colorbar), so that
doesn't seem to be
the way to do it.
Can anybody tell me the correct way to do it?
Thanks, Mark
Try
b = colorbar(a, ticks=linspace(0, 10, 3))
