Choose diagram with parmeter in ssrs report

Hi!

I have multiple diagrams in the same area of an SSRS report and i would like to choose which report to display with a Parameter. But i dont know how to fix that.

As an example i have four diagrams that i would like to choose from with a parameter i would like to do something like below but that is not working. Any Ideas how to solve this issue?

Best regards Arne Olsson

switch (Parameters!DiagramNamn.Value = "Diagram1", Diagram1,
		Parameters!DiagramNamn.Value = "Diagram2", Diagram2,
		Parameters!DiagramNamn.Value = "Diagram2", Diagram3,
		Parameters!DiagramNamn.Value = "Diagram2", Diagram4)
