Convert 2D heatmap to 3D bar plot

Hi All!

I have a heatmap (attached below, made using imagesc) which represents the average result of 10 simulations. I would like to include the standard deviation for each parameter combination as well. What I would like to make is a 3D bar plot where the height of the bars corresponds to the standard deviation of a specific parameter combination and the color of the bars is the same as in the 2D heatmap. How could I achieve this?

Thank you for your help in advance!

There are two approaches I can think of, but they requrie some manual formatting. Both use bar3.

1. Color 3D bars by height.

2. Assign a solid color to each bar based on height.
