Hi all

I regress y on X1 and X2 per each industry and year group. My coefficient of interest is the coefficient on X2. I get a coefficient for each industry and year group.

I want to create a 3D graph that shows the coefficient of interest for each industry every year (each industry's coefficient can be presented as a bar every year or alternatively use a 3D surface graph).

How can I do these in Stata?

Thanks
