How to Create a Chart from a Subtotal Column in a Matrix Visual
As shown below, I have a table (Table 1) in long format with three columns: Period (from 1 to 3), FS_Item (Revenue, COGS, OPEX, Assets), and Amount (numerical). From that table, I can create a Matrix visual (similar to second image below) that filters out one value from FS_Item (Asset) and sums up the remaining three values to come up with a Total column (Revenue - COGS - OPEX).
I would like to create a Chart that plots Period and Total (the yellow highlighted columns). I assume that I would first need to create a table that is identical to my Matrix visual.
