Stacked Line Chart to isolate values instead of summing them

[tmauney (Taylor Mauney)]

I want to create a stacked line chart that will show how each item is performing over time: the first item shows the true numerical value month to month, but the rest of the items then add up the values even when “cumulative data” is unchecked. When I hover over the plot point, it lists the true value, but visually I’m not able to see how the items are performing in comparison to each other over time because it calculates the sum of all items’ numbers.
