Setting a chart reference in Numbers

Is this possible with AppleScript? I didn’t see any chart info in the Numbers dictionary. I can reference a chart like so:

set thisChart to chart 1 of sheet 1

But the only properties returned of the chart are:

{position:{197, 138}, height:163, width:163, class:chart, parent:sheet 1 of document id “EF9F7C76-E417-4EE4-BDA8-F20A2410C206” of application “Numbers”, locked:false}

What I want to do is create a small app that I can pop open from the Dock, add a row to a table, set the data and formula for the cells of that row and then set those cells as the data reference for an existing chart.

Thanks in advance
