Line Chart Widget with multiple metadata vars

Line Chart Widget with multiple metadata vars

Hi guys!

I am trying to use a line chart widget with multiple lines. The data come from only one var with multiple metadata properties, but, I dont know if is because is the same var, the line chart remove all the var, leaving just one.
Let me put some images:

two vars with the respective metadata formula to get the correct information.


After save, just one var.

Is not possible to do what I am trying?
