How to set marker color different from line color in chart?

entimo

Hallo,

I want to set different colors for the line series marker and the line color. I would like to have a series with a black line and empty (white) markers. I think to have set the colors but the effect is, that when I take color white, the marker is ok (filled white) but the line in invisible (white?). It is possible to have different colors for marker and line? It is possible to have different line styles for the line and the marker border, too? I had the problem that the border was dashed when the line was set to be dashed. I am using birt 2.5.2.

my code:

//
// create line series
//
final LineSeries lineSeries = (LineSeries) LineSeriesImpl.create();
lineSeries.setSeriesIdentifier(ident);
lineSeries.setCurve(false);
lineSeries.getLabel().getCaption().setValue(ident);

//
// set line attributes
//
final LineAttributes lineAttributes = lineSeries.getLineAttributes();
lineAttributes.setColor(lineColor);
lineAttributes.setStyle(lineStyle);
lineSeries.setPaletteLineColor(true);

//
// set marker attributes
//
final EList<Marker> markers = lineSeries.getMarkers();
final Marker marker = markers.get(0);
marker.getOutline().setStyle(LineStyle.SOLID_LITERAL); // funzt leider nicht!?
marker.setType(markerType);
marker.setFill(markerColor);
marker.setSize(fSizeMarker);

final Query lineQuery = createQueryDef(dataName);
lineSeries.getDataDefinition().add(lineQuery);

//
// series definition and palette
//
final SeriesDefinition lineSeriesDef = SeriesDefinitionImpl.create();
// final Palette seriesPalette = PaletteImpl.create(lineColor);
// seriesPalette.getEntries().add(markerColor);
// lineSeriesDef.setSeriesPalette(seriesPalette);
// lineSeriesDef.getSeriesPalette().shift(-fPrimAxisY.getSeriesDefinitions().size());
lineSeriesDef.getSeriesPalette().update(markerColor);
lineSeriesDef.getSeries().add(lineSeries);
lineSeriesDef.getQuery().setDefinition(BasicTool.dquote(ident));
fPrimAxisY.getSeriesDefinitions().add(lineSeriesDef);

Thanks in advance,
Bertram

Hi Bertram,

As far as I know, the line color is set by the series palette and if you change the fill color of the marker in the chart script, the line color doesn't change. So, if you set the first color in your chart palette to black and then in your chart script do:

beforeDrawDataPoint{
fill.set(255,255,255);
}
