Passing More than 1 value to the same Line chart

[triekong]

i have a line chart on my dashboard. it gets its value from being passed a variable expression from the previous tab.

i have a button "PLAN".

The Goal here is that when "PLAN" is selected, instead of the expression which was passed, it should switch the line's expression to   "=sum(Plan)"

this would normally be easy with a regular line chart with regular expressions entered.

But the problem i'm having is the line chart already contains a trigger variable and an expression.

so i want to add another trigger from my "PLAN" button.

how do i make the chart switch between the passed variable expression (=$(=(v_VariableTransfer)) and the button selection variable (=sum(Plan))?

i have attached the QV file !

Let me know if it makes sense. thanks!
