Show Bar Graph with logic

Good morning Team,

I hope you can help me, I'm trying to make some measures.

It's that I want to show a result.

Next:

Create a test table

I'm not getting

It's that I want you to show me the difference but when there is no such difference do not show me anything

That is, show the contrast between the Real Income vs Estimated Income in a single column.

But don't add up, but when the estimated income is 0, it adds it to real income.

Nose if you understand well, I hope if !

Thanks a lot!
