Hi,
I wanted to try the following script on a chart:
Chart c = ChartWithAxesImpl.create();
c.setDimension(ChartDimension.TWO_DIMENSIONAL_WITH_DEPTH_LIT ERAL);
String script = "function beforeDrawDataPoint(dataPointHints, fill)
{" +
"val = dataPointHints.getOrthogonalValue();" +
"if(val < 0) {" +
"fill.set(255, 0, 0);}" +
"else {" +
"fill.set(0, 0, 255);}" +
"}";
c.setScript(script);
[...]
public final void paintControl(PaintEvent pe) {
try {
idr = ps.getDevice("dv.SWT");
} catch (ChartException ex) {
ex.printStackTrace();
}
idr.setProperty(IDeviceRenderer.GRAPHICS_CONTEXT, pe.gc);
Composite co = (Composite) pe.getSource();
Rectangle re = co.getClientArea();
Bounds bo = BoundsImpl.create(re.x, re.y, re.width, re.height);
bo.scale(72d / idr.getDisplayServer().getDpiResolution());
Generator generator = Generator.instance();
try {
IDisplayServer server = idr.getDisplayServer();
GeneratedChartState state = generator.build(server, c, new
ScriptHandler(), bo, null);
generator.render(idr, state);
} catch (Exception e) {
e.printStackTrace();
}
}
};
But when I execute this, I get the following stack trace:
org.mozilla.javascript.EvaluatorException: Constructor for "Object" not
found.

Stefan,
It should be beforeDrawElement. beforeDrawDataPoint has a Label as
parameter, not a Fill object.
Thanks,
