You can use this simple way to Open or Hide graphs based on your selection. I have attached the sample apps.
There are basically 4 charts. From the list box, Based on your selections, that particular chart will open and other will hide.
Hope it was helpful.

The example with the selections works fine - and is a good approach as it is data aware. If you want to use a button there is an approach that I posted in a different thread:
This uses the Show Condition as with the other example, but the condition is based on a variable set by the button.
