I recompiled JFreeChart and JCommon with an namespace-extension - we have some old sources with JFreeChart 0.9x. I used in a Servlet (all imports are "import temp.org.jfree...") : JFreeChart chart = ChartFactory.createXYLineChart( "XY Series Demo", "X", "Y", this.getDataSet(), PlotOrientation.VERTIC...

Found something else :shock: I can dash or dot my lines - wonderful. But if i add a second axis, and to that second axis a dataset with some series - the stroke-style, line-colour, line-thickness are always the same like the corresponding index of the first dataset. As example 2 axis, 2 datasets, 2 ...

The mistake was that I used the XYItemRenderer :) Now everything is fine.

The only thing you can get is a point. For a line you need minimal an vector := 2 points.

Wonderful, thanks a lot for the quick help. Just a little question, if i use setVerticalTickLabels(boolean) the labels are rotated by 270 degree (if it is counterclockwise), but a rotation by 90 degrees clockwise, would be correct for left-to-right-readers. Is it possible to print it in the other ve...

Marking Points on TimeSeriesChart

Hi all, iam a little confused how to set marking Points on lines. My Problem is that i have special values at my TimeSeries, as example y:=3 x:=03.07.2006 is a special point and should be marked, with a point or something else. the next point y:=2 x:=04.07.2006 is not a special-point - so it shouldn...
