Re: Copy to Clipboard IOException (ARGB channel no longer supported for JPEGs)

Hi @lynnskii - have you thought about creating a Pull Request to provide your fix?

It seems a straightforward fix, you can create a PR here:
https://github.com/jfree/jfreechart/pulls

I'm also _suffering_ from the issue, so if you don't I'm quite happy to.

Re: getEntity() not working with altered PlotOrientation

After some support from am algorithmically gifted colleague of mine I'm now aware of the solution to this problem. The addEntity method is responsible for creating the 'hotspot' it reacts to, using its x and y coordinates. When the addEntity method is generating the hotspot ellipse shape it switches...

getEntity() not working with altered PlotOrientation

Hi all, I'm trapping the chartMouseClicked event to let the user select a data-series in my TimeSeries plot. All is working fine, until I switch the PlotOrientation from Vertical to Horizontal - then the getEntity() method on the ChartMouseEvent just returns the background plot - it fails to recogni...

Ability to drag data points?

Hi all, I've a use-case where I'd like users to be able to drag data-points in a scatter diagram - so changing the data value in the underlying dataset. This doesn't appear possible from the demonstrator or the forum contents? Am I missing something? If the capability isn't in JFreeChart I'm willing...

thanks for coming back to me David, Unfortunately I omitted to indicate that I wish to show my 'range' data (distance in this instance) along the horizontal axis. Extending from your example, I would replace the domain axis with a NumberAxis. At this point, would it have just been better to start wi...

Vertical date axis on TimeSeriesChart

Hi all,
I'd like to produce a scatter plot with date data on the vertical axis. TimeSeriesChart appears to only support date on the horizontal axis. Can this be overridden? Or should I just work from an XYChart?

thanks in advance,
Ian

Good advice

Thanks for that, "silent". At first your recommendation didn't seem an option - since the target application is an open-source app for which no licensing costs are required. On reflection though, the "unlimited distribution" cost is less than I'd expect SWT-JFreeChart to cost, and it may be an optio...

Home for SWT JFreeChart?

Hi all, I'm updating a Swing application (www.debrief.info) to Eclipse. The application makes a lot of usage of interactive Time-Variable plots via JFreeChart. I'm aware of the SWT_AWT wrapper available but I don't expect it to support the interactive (zoom/pan) features of JFreeChart as well as I'd...
