Re: XYStepRenderer Center Item Label on the Step
Hi! It is only possible to adopt where the step should be made via setStepPoint() . The position of the label itself is currently fixed. This would be a useful extension to the XYStepRenderer. Please file a feature request here and provide a patch if possible. If you want to have a go, start with ov...

Re: Horizontal Bar Chart: Display values at end of bar
Hi!
Use an XYTextAnnotation or CategoryTextAnnotation to display arbitrary text wherever you like. To find out the max-value of all bars, just iterate through your dataset.

Re: Hi-lo value between two line graph
I don't think so, but I never used this renderer myself.
You could either try to extend the renderer or, you could use XYTextAnnotations to output the required values.

Re: dataset with two timeseries, one empty
This is probably due to bug #3445507, which is already fixed in SVN. You could either use an older version of JFreeChart or a 1.0.15-SNAPSHOT version from here.

Re: Polar Chart : rotate axis line
Hi! You don't mention the used version of JFreeChart but JFreeChart 1.0.14 got some improvements for polarcharts. You can set an angle-offset via PolarPlot.setAngleOffset() which allows to start with 12am at whatever position you like. However, the axes themselves cannot be at arbitrary angles but o...

Re: Bug - AutoRange in TimeSeriesChart
Hi!
You have three possibilities:

You have three possibilities:
- either you checkout JFreeChart from it's source repository (which is described on this wiki page).
- or use a 1.0.15-SNAPSHOT from this maven repository.
- or wait for the 1.0.15 release to happen. But please don't ask when it is expected

Re: Jfree chart and OpenSDK Issue
Sound's like an anti-aliasing issue. Try turning anti-aliasing off via the RenderingKeys as mentioned here.
Example:

Example:
Code: Select all
chart.getRenderingHints().add(new RenderingHints(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_OFF));

Re: Spam in 2013
Hi David! I also realized the increased spam messages and am (more or less) regularly deleting spam posts. However, I don't think we will benefit much from the new account activation procedure. An admin cannot tell in advance if a new user is malicious or not. So he would have to grant permission to...

Re: Is JFree charts provide geographical Charts ?
Hi!
See this thread for more information about geographical charts. This is however not included in 1.0.14 and probably won't be in 1.0.15. I still hope we can integrate it sooner or later with the official release.

Re: Help needed getting setItemMargin(0.0) to work ........
What exactly is your problem? "Stopped working" is not very helpful.
Regarding the IntervalMarker: run the demo and have a look at the examples in Miscellaneous/Markers.

Re: ValueAxis inside data area.
Yes, that's what I mean. And you can use drawZeroDomainBaseline() and drawZeroRangeBaseline() and related methods for setting the paint.

Re: ValueAxis inside data area.
Hi! To my knowledge there is currently no support for drawing axis inside the XYPlot (PolarPlot has it, but that's probably not what you want). But you have the possibility to draw the axis on the plot's edges and add zero baselines. What you do not get this way is moving the labels and ticks inside...

Re: Looking for ways to update JFreePieCharts on the fly
Hi!
If you use the default dataset implementations, that happens automatically.
If you implemented your own dataset you have to notify the listeners. Have a look at the AbstractDataset.fireDatasetChanged() method for details.
