Chart back" snippet"

I have a queue on the left hand side of my page which when clicked sets conditions on a model to control a chart on the right hand side.

The chart has a drilldown option to slice my data a different way, but if the user then selects a different entry in the queue without clicking Back on the chart, the chart stays on Chart 2 and presents a confusing view to the user.

Does anyone have a snippet that I could add to my queue actions to back the chart up to Chart 1?

Thanks!
Linus
