# [Matplotlib-users] Understanding axes position

```Hi all,

what I’m trying to do here is having third plot with its base aligned with the others and with reduced height (the final aim is custom positioning a colorbar).
As you can see I’m getting the wrong position. What am I missing?

Thanks for any help
