pie chart data store

[spbroom]

Hi, I have a pretty simple pie chart with a JsonStore as its data source. I dont want use the actual value in the dataField but rather that value after a function has been applied to it. So instead of dataField:'cost' I'd like to use something that would allwo me to return cost*someotherValue.

A bit like how a renderer can be used for a grid.

Anyone know of how to achieve this with a chart.

I recommend using the CalcRecord user extension to create an extra field that holds that value.

The only other solution would be to override the Ext.Chart.refresh method.

I don't think you can do that in a single chart. You'll need 3 charts for that.
