Using a Control multiple times on a page with different chart and data

I'm trying to use a control (tried drop down, fixed size, input box) on a page. I have the same control with different charts. I want to select a different input for each chart and have it display data for only that input in that chart. Is this possible?

I've grouped the control and charts - doesn't work.
I can select (drop down) or input (input box) the value I want but it applies it to every chart on the page and then won't let me change it and select something else. 

EXAMPLE: 
Month: Jan, Feb, Mar
Some records with Jan, different records with Feb, others with Mar.
I want to show one chart with just the Jan records, one chart with just the Feb records, etc.

With a drop down control, I can select Jan and then I never see Feb or Mar in any of the other control boxes - including the original. 

With an input box I can input Jan, get records. Next box type Feb and get No Data when there is actually data. 

Not sure what I'm doing wrong, but I think this should work.
