Hi,
I am creating a pie chart. The interesting thing is that the data contains
color codes for status such as red, green, amber. I would like the pie chart
colors to match my data colors.
It doesn't look like you can control slice colors using the data set
directly - which would be really nice feature.
So what is the recommended way to make this happen, fiddle the sql, add
some javascript hooks?
Any thoughts appreciated,
Cheers,
Conor.

Hi,
Indeed you cannot control the slice colors directly from the dataset, but I
think you should be able to achieve the effect you want by scripting.
Implement this script function
function beforeDrawDataPoint( dph, fill, context ){}
dph is the DataPointHints instance and can give you access to the data
value, then you can change the fill to use the color of the data. Look at
the org.eclipse.birt.chart.examples plugin for script examples.
Thanks,
David
