StackedBarChart+line (Overlaid)

[guest]

Hii,

I am trying to put the stacked bar chart and line chart together...overlaid charts...but, the stacked bar chart is just taking the data for one bar...the line chart is coming fine.Following ís the code..

Code: Select all

		JFreeChart chart = null;
		CategoryItemRenderer renderer2 = new LineAndShapeRenderer();

		CategoryPlot plot = new CategoryPlot();
		LineAndShapeRenderer linerenderer = null;
		CategoryItemRenderer barrenderer = new StackedBarRenderer();
....
....
...

				if ("BAR".equals(key) || ("STACKEDBAR".equals(key))) {
					plot.setDataset(
						(CategoryDataset) provideDataset((ArrayList) value));
					plot.setRenderer(barrenderer);
				} else if ("LINE".equals(key)) {
					plot.setSecondaryDataset(
						counter,
						(CategoryDataset) provideDataset((ArrayList) value));
						maxRangeValue = DatasetUtilities.getMaximumRangeValue((CategoryDataset) provideDataset((ArrayList) value));
						if(counter==0){
							plot.setSecondaryRenderer(0, renderer2);
						}else{
							plot.setSecondaryRenderer(counter,new LineAndShapeRenderer());
						}
						
						linerenderer= (LineAndShapeRenderer) plot.getSecondaryRenderer(counter);
						linerenderer.setDrawShapes(false);
						counter++;
				}

I believe the renderer i m using for stacked bar is not correct...can anyone give me idea??

It's not clear to me. If you can, post a small sample application that I can cut and paste then run.

Hii David,

Thanks for your reply. Actually i was doing mistake with my dataset. Just now, i found it and was about to post a message. Well, but i m having another problem now.

The thing is, i set the autorange true....it works fine. But, now the chart has a gap between the 0 level and the x axis.

How can i fix this??

There is a setAutoRangeIncludesZero(boolean) method in the ValueAxis or NumberAxis class.
