Show values when chart is clicked

[snowy]

Can Active Reports show values when charts are selected? I want it to behave like the mouseover event on a standard Cognos chart.

This guy (http://www.performance-ideas.com/2011/10/05/ibm-cognos-ipad/) has an example where it works, but I can't get my Active Reports to do anything when they're clicked. I've had a play with the chart Interactive Behaviour properties but to no avail.

I don't really want to start messing around with exploding pie charts etc, if only because the report's file size is already too large. Another data deck in there would blow it up!

Any thoughts?

I should probably clarify: I'm talking about an iPad report so I mean "touched" rather than "clicked" :)
