Hi,
 
In the commercial release of BIRT, which you seem to be using, the default chart format is HTML5 and the charts are generated using the Highcharts library. In Open Source BIRT, charts are generated using a different API. For that reason, scripting is done differently. In Open Source BIRT, scripting is done using the onRender method of the chart and you have access to different function stubs, including beforeDrawLegendItem, to interact with the chart engine API. In commercial BIRT, scripting is done in the scripting tab of the chart wizard (as shown in your screenshot) and you interact with the Highcharts API. This API is documented at api.highcharts.com. 
 
if you need help modifying the legend using the Highcharts API, you can search this forum or post a more detailed question.
 
Hope this helps,
 
P.
