JFreeChart: CombinedDomainXYPlot

I have a CombinedDomainXYPlot with 3 subplots (XYPlot).

I am trying to make the base shape visible and fill it with this code, but it does not seem to work. If possible, please let me know what I am missing. Thanks!
XYItemRenderer r = plot.getRenderer();
        if (renderer instanceof XYLineAndShapeRenderer) {
        	XYLineAndShapeRenderer lineAndShapeRenderer = (XYLineAndShapeRenderer) r;
        	lineAndShapeRenderer.setBaseShapesVisible(true);
        	lineAndShapeRenderer.setBaseShapesFilled(true);
        }

Strange that it does not work.
Maybe you could try to use ...ShapesVisible(..) and ...ShapesFilled(...)  methods specific to series ?

Can you tell me how I can do that?

Even this code does not seem to work:
final XYItemRenderer renderer = plot.getRenderer();
		
		if (renderer instanceof StandardXYItemRenderer) {
			final StandardXYItemRenderer itemRenderer = (StandardXYItemRenderer) renderer;
			itemRenderer.setSeriesStroke(0, new BasicStroke(2.0f));
			itemRenderer.setSeriesStroke(1, new BasicStroke(2.0f));
		}
		
        if (renderer instanceof XYLineAndShapeRenderer) {
        	XYLineAndShapeRenderer lineAndShapeRenderer = (XYLineAndShapeRenderer) renderer;
        	//lineAndShapeRenderer.setBaseShapesVisible(true);
        	//lineAndShapeRenderer.setBaseShapesFilled(true);
        	lineAndShapeRenderer.setSeriesShapesVisible(0, true);
        	lineAndShapeRenderer.setSeriesShapesFilled(0, true);
        }

Maybe you can post your code - I could then try to play with it

For me to play I need aself-sufficient code
- this is just part which I cannot compile.

Put System.out.println(something)
within the  if (renderer instanceof XYLineAndShapeRenderer){...  }
to check if it goes there

I left out the block of code that adds values because I am not allowed to share that code. Moreover, it is dependent on other packages in my project.

Would it be possible for you to add dummy values to the charts. Sorry if I am asking too much!

There is no header part either - class, main() etc.

Just invent some simple data.

First place printout.

And the forst  "if" is working ?

I was looking at the class hierarchy and i don't think
it can be instance of both - maybe i'm not right

No, I think if you put three points in each and add the class and main, etc  - that would be good - you should have beetter idea what kind of
numberss should be there
