lines are easy ... create two entries in a dataset and add to an XYSeries...

how to add a text in a chart ??

like a java.awt.Graphics ..

g.drawLine(int x1, int y1, int x2, int y2)
or
g.drawRect(int x, int y, int width, int height)
or
g.drawString(String str, int x, int y)

I create very well my chart ( thanks to jfreechart ) ,
and I want add some information in the chart ..

for example ... a horizontal line starting a 0.

I have a CandlestickChart .. and a TimeSeriesCollection in the SecondaryDataset.. ( from - 50 to 50 )
