I have stock graphs and would like to draw lines over the graphs. Like a straigh line to see where it cuts the graph or draw fibonacci lines or other studies.
I that supported by jFreeChart?
thanks in advance,

Hi,
Drawing trend lines, is not supported by JFreeChart, but you can do it implementing MouseListener on a chartPanel.
Also you can use ShapeAnnotations to draw your lines or other Items

You can do that. Just calculate the trendline as a new series from the same data and use a CombinedPlot to merge the original plot and the one generated from that calculated series.
