trying to export a RingChart as png, I don't use title or legend, just the chart, still I have white space on the top and bottom:

creating via factory:

    JFreeChart chart = ChartFactory.createRingChart(
            null, 
            dataset, 
            false,
            false,
            false
    );

the following didn't help:

chart.setPadding(new RectangleInsets(0, 0, 0, 0));

RingPlot plot = (RingPlot) chart.getPlot();

plot.setInsets(new RectangleInsets(0, 0, 0, 0.0));

I need the chart to be without any margins for the exported image, any idea? Thanks

Java2D or Swing? You might be able to optimize the chart's aspect ratio using one of the approaches shown [here](https://stackoverflow.com/a/10277372/230513). – trashgod Jan 01 '21 at 18:22
thanks @trashgod, Java2D (just need the chart image file), I will look into it – Doron Levi Jan 07 '21 at 13:07
As I recall, the ring resizes to fill the narrowest dimension. – trashgod Jan 07 '21 at 13:22
