Combine Candlestick and Line Charts

Post by Sianis » Tue Aug 11, 2009 11:43 am

Hi!

Is it possible to combine Candlestick and Line Charts in same chart? I saw that Candlestick is type XY as Line too, but they have different renderer.

Thank you for your help!

Okey, I solved it.

Key is:
XYPlot.setDataset
XYPlot.setRenderer

Re: Combine Candlestick and Line Charts

Post by itsmaddy » Mon Apr 25, 2011 7:00 am

The exception that usually comes is "timeseries cannot be converted to ohlcseries".
to overcome this you have to set renderer for that series as XYLineAndShapeRenderer.
XYDataset collec = createMADataset();
xyplot.setDataset(2, collec);
xyplot.setRenderer(2, new XYLineAndShapeRenderer());
The above program shows how to add a timeseries on candlestick chart.
Try running the above program .It has the code that you require.
