I have a Line and Stacked Column chart to which I want to add a "Grand Total" label at the top as the sum of the components in the stack.
I'd like to create a measure that sums the values in the Total column (in the data shown at the bottom of the screenshot) as "Grand Total" so that it can be applied to the chart. I've had no luck using the SUM and SUMMARIZE functions so far.
Suggestions to achieve this are much appreciated. Thanks in advance.
