Use custom animations on the graphics for your data points.  You can add
animations that make the iriginal graphics disappear and others appear,
simulating the change.  Or you could even draw custom paths and make the
points move from their original position to a new one.

Hi

You could use something like Crystal Excelsius - if you have the budget for
it :-)

I would add an object animation to the chart. Here's how.

Right-click the chart, choose Custom Animation.

Add Effect | Object Actions | Open. (I think Edit will actually work the
same in this case.)

When you click the mouse, the chart will open in MSGraph.

If you want the chart to open when you click it, then make this a trigger
animation instead of a regular "on mouse click" animation. Here's info on
triggers to get you started: http://www.echosvoice.com/triggers.htm
