Create another pivot and link it to the slicer you use to manipulate your chart and pick the title from this newly created pivot by giving cell reference.
This is a great solution but when I add another pivot table and chart on the same worksheet it doesn't work. I would like a solution where I can use the same slicer for all pivot charts or have a different slicer for each chart. Error: run time error 5, Invalid procedure call or argument. Any suggestions please?
