Re: [Matplotlib-users] how to put colorbar label beside the handle?

[Sterling S. <sm...@fu...>]

Chao,

The secret is positioning your ticks.  I list here an untested attempt at putting the labels at the average of the current and next levels:

cbar.set_ticks((cbarlevel[1:]+cbarlevel[:-1])/2.)

Because you have less ticks, then you will want to remove the line

cbar_level.append('')

Hope that helps,
Sterling
