Reading through the documentation and code explains the zoom selection rendering differences. It would be nice still to be able to turn on buffering on systems that use scaling with HiDPI monitors.

This is a feature where the ChartPanel keeps an offscreen image as a buffer for the charts it draws. Unfortunately it doesn't work well with retina displays, so for better output quality you should disable the buffering via the constructor. This also appears to be an issue with Windows 10 display s...

1. Have you tried setting the dismiss delay, ChartPanel.setDismissDelay()? 2. If you search the board, you'll find some suggestions on finding the nearest point. Here is one version: private ChartEntity findNearestEntity( ChartMouseEvent event ) { ChartEntity entity = event.getEntity(); if( ( Object...

I'm looking into moving from Java 8 to Java 11. I'm running Windows 10 with a monitor that has scaling turned on at 125%. Under Java 8, charts render nicely, but under Java 11, it appears all the elements in the chart are scaled by the 1.25 making them look terrible. Turning windows scaling off fixe...

John,

Yup, the StandardXYItemRenderer does respect the rendering order for both the shapes and the lines. Thank you!

Example: There are two series in the XYSeriesCollection. Both represent the same line, but one has more point defined between the endpoints. The series with more points is added to the collection after the one with fewer points. The one with fewer points is rendered with a stroke. I would expect the...

When extending JFreeChart objects like ValueAxis and XYLineAndShapeRenderer, how important is it ensure that any added fields are serializable and that equals()/hashcode() take them into consideration? I recently ran some JFreeChart code through findbugs and was surprised at how many warnings were g...

Thanks, that all makes sense.

Any idea why DefaultCategoryDataset doesn't have a method that allows you to add values without calling fireDatasetChanged()?

I'm seeing some puzzling behavior. I have a chart with one TimeTableXYDataset with 10 series in it. I update the chart clearing the dataset then iterating over an internal datastructure and adding points back into the dataset. Chart updating seemed a little slow so I wrapped the dataset modification...

Wow, that was quick. Thank you.

David,

It appears XYBarRenderer ignores that flag. It overrides findRageBounds(). Is this an oversight or intentional? Thanks,

bump.

I'm surprised, has no one tried to do this, or am I missing some obvious basic support in JFreeChart that does this?

I'd like to change the shape of a point when the mouse is hovering over it. Any suggestions on how to do this?
