ThreadCheckingRepaintManager can be very helpful, but it may not be dispositive. Other problems may exist. It's hard to say without a complete example and relevant version details. This example may provide a useful reference point from which to start trying to reproduce the effect you're seeing.

Also look at DatasetUtils methods that iterate over the items in an XYDataset to find the bounds.

Given a CategoryAxis, try setTickLabelsVisible or setCategoryLabelPositions with the desired position; alternatively, consider a SlidingCategoryDataset.

It looks like you're working from the examples examined here . Your listener can use the series index or item number to index your label array: if (e.getEntity() instanceof XYItemEntity) { XYItemEntity i = (XYItemEntity) e.getEntity(); System.out.println(i.getSeriesIndex() + ":" + i.getItem()); } Al...

For reference: Filling area under normal distribution curve…

I don't see way to update the list of symbols used by an existing SymbolAxis, but you can creates a new one and apply it to your plot; listeners should see a new PlotChangeEvent.

XYLineAndShapeRenderer renders lines and shapes in separate passes. You might look at other implementations of XYItemRenderer, such as StandardXYItemRenderer.

It looks like the LogarithmicAxis implementation of refreshTicksHorizontal and refreshTicksVertical creates new instances of NumberTick that default to TickType.MAJOR . Because no tick is TickType.MINOR , setMinorTickMarksVisible(false) has no apparent effect. Your implementation would have to speci...

You can use a custom DrawingSupplier, like this.

Several examples are examined here.

To learn what ChartEntity was clicked, add a ChartMouseListener to your ChartPanel, for example; dragging a point is examined here.

For crowded bar charts, I use SlidingCategoryDataset. Alternatively, consider switching to XYDataset and use SymbolAxis.

The API suggests that you override getItemShape().
