Subtraction problem

[rafamorim87]

Goodnight

I need to create a graph that shows the difference between 2 previously calculated values.

It's a simple calculation, but the result is wrong.

In the image I built 3 graphs. The first two are correct. The third party should present the value of the difference between the value of the first and the second.

Any idea how I can solve it?

Thank you in advance

@rafamorim87 , if the first graphs are using any visual level, then that will not work.

But looking at the value, seems like the axis(Table) used is not joined with tables you have those measures
