How to Create a Chart from a Subtotal Column in a Matrix Visual

[saddas]

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. 

Any help would be greatly appreciated. Thanks.

Great, thanks very much. I had figured out a longer formula (see below), but yours is much more efficient.

Long version of formula:

Amount New = CALCULATE(SUM(Sheet1[Amount]),Sheet1[FS_Item]="Revenue") + CALCULATE(SUM(Sheet1[Amount]),Sheet1[FS_Item]="COGS") + CALCULATE(SUM(Sheet1[Amount]),Sheet1[FS_Item]="OPEX")

Simply create a new measure with the following formula:

Amount New = CALCULATE(SUM(Sheet1[Amount]), FILTER(Sheet1, Sheet1[FS_Item] IN {"Revenue", "COGS", "OPEX"}))

And then create the table orgraph based on Period and Amount New fields
