After posted my same question yesterday, I found a solution for this problem. It is to set one dataset with three TimeSeries:

TimeSeries sell_series = new TimeSeries("Sell", Month.class);
TimeSeries hold_series = new TimeSeries("Hold", Month.class);
TimeSeries buy_series = new TimeSeries("Buy", Month.class);

TimeSeriesCollection dataset = new TimeSeriesCollection();
dataset.addSeries(sell_series);
dataset.addSeries(hold_series);
dataset.addSeries(buy_series);

then define color for each dataset:
XYBarRenderer renderer = new XYBarRenderer(0.01);
renderer3.setSeriesPaint(0, Color.red); //sell
renderer3.setSeriesPaint(1, Color.green); //hold
renderer3.setSeriesPaint(2, Color.blue); //buy

and remove tick in y-axis:
Axis.setTickLabelsVisible(false);

The key point for this solution is to assign either 0 or 1 for all TimeSeries. For example, if it should be sell in Mar 2005, then
sell_series.add(new Month(3, 2005), 1);
hold_series.add(new Month(3, 2005), 0);
buy_series.add(new Month(3, 2005), 0);

Try it and good luck.

Hey thanx !!
I also wanted to know whether this is possible using Netcharts Pro. This time we can have either this bar or even an Image .
I actually want a mulitcolored side bar ( in place of y axis) in a XY graph.What I am hoping to get is some api in Netcharts pro to set this image at Y axis of the graph.

Any solutions are most welcome and greatly appreciated.
