Hi all,
I plotted an imnage with a custom color map and a discrete color bar with the following code (see code and figure below). However, the tick labels at the discrete colorbar are placed in the middle of the discrete sections. I would like these shifted to the upper part of the discrete bin edges, e.g. 2 at the white/light blue border, 4 at the light blue/darker blue border, etc. How can I do this?
Thanks!DLS_ex.png

Hey,
It is my understanding that you want to change the location of the tick labels in your image.
You can do this by changing the 'Ticks' property of the colorbar object ('h' in your case). For your code, you can try adding a positive constant to the default 'Ticks' array.
