I guess this would be a tool limitation. But one Question from my side if you want to display the latest month data on chart why can't you filter.
As Krishna said it's not doable ... the setting is "always" or "never" (ok, on mouse over).
Basically there is pivot table data with say last six months data and I am converting the pivot table data view to chart view so having last six months data displayed on line chart. of which customer wants to display the data labels only for last month.
Yes, so his first answer (not possible) still apply.
He was asking because maybe you wanted in the chart only the last month and not the previous ones.
But you want the 6 months and showing the value of last month numbers next to where your lines end (and that the not available option)....
Create two seperate analysis one for pivot and another for chart and keep it in same dashboard page
