Hi,
I have Line Graph with colulmn called: Savings [%].
It is calculated as follows: (Savings [EUR] * 100.0) / Amount [EUR]
And graphs looks like:

Three colors it's a three different organization (for example A,B,C)
And now I want create a grand total on graph, for all organizations but BY MONTH. For each month calculated grand total.
The grand total for this should be calculated as follows: (SUM(Savings [EUR]) * 100.0) / SUM(Amount [EUR]). In pivot table it's working fine, when I have on savings [%] column, aggregate rule is Default and it's ok.
But how can I add this on graph? With ma custom formule and not divide by organization?

The above graph has this calculating because I not use Vary Color By Organization.
I think that I want to merge above two graphs. Can I?
