Correlation Plot visual - issue

Hi team,

I’m trying to visualize in a Correlation plot visual, the correlation between the Values of two different tasks. Here is my data:

I have installed R and the ‘corrplot’ package, but when I try to put “Task” field and Value, no data populates in the visual. The only way to see data in the visual is to put two value fields, but no task (text).

The end result I’m looking for is this:

*The first left bubble should be the correlation between sum of the values of AA1 and sum of the values of AA1. The second bubble, row one, is the correlation between sum of the values of of BB2 and sum of the values of AA1.

Do you have an idea is it possible to present my data in this look with a correlation plot visual or what transformation should I make?

Thank you.
