DeviationRenderer and null values

Hello,
Is there a way to change the behavior of a DeviationRenderer at null values? The standard way is to disconnect the line but continue the drawing of the interval (the shading). I would like to have the interval also being disconnected at null values.

Thanks,
Julia

Rendering Middle Millisecond instead of first Millisecond

Hello, I have a chart with XYLineAndShapeRenderer and a TimeSeries with RegularTimePeriods Day. The shapes are rendered at the first millisecond of each day. But I would like to have them rendered at the middle millisecond (at noon). Is that a setting in the renderer? I can make a workaround by usin...

Re: Null values in TimeSeries

You were right, null values were not added to the timeseries (sorry for not checking this before). This code is about 10 years old and I read about some bugs with null values those days. Maybe that's why.
Anyway, now it works fine, Thanks!

Null values in TimeSeries

Hello, How can I set the behaviour of null values in a Timeseries? In the examples I found (e.g. here http://www.java2s.com/Code/Java/Chart/JFreeChartTimeSeriesDemo4usinghourlydataandincludinganullvalue.htm) the method org.jfree.chart.ChartFactory.createTimeSeriesChart(String, String, String, XYData...

Re: Bug - AutoRange in TimeSeriesChart

Great! I also noticed this problem and I'm happy that it is solved (already on 2011-12-03 as I saw in the commit). But there comes a stupid question to me: How can I get the updated jar files? Downloading the jfreechart-1.0.14.zip from sourceforge gives me still the version from 2011-11-20. Do I nee...

Re: labels of rangeAxis,domian and legen are NOT visible

Hi, Is there any news about this topic? So far I used SWT_AWT to include JFreeCharts into Eclipse. But since the experimental swt.ChartComposite is supposed to be faster, I wanted to try this. I found two examples in the internet: 1) http://www.devdaily.com/java/jwarehouse/jfreechart/swt/org/jfree/e...

Re: findSubplot(): strange behaviour

Thank you, Dave, for your very helpful answer! Indeed, case (1) was true. I didn't know that the maximum draw size is limited (768 x 1024 pixel) and one has to change it. The following lines of code now solved the problem: // get the monitor size (under Eclipse), in my case 1050 x 1680 pixel Rectang...

findSubplot(): strange behaviour

Dear all, I found a strange behaviour of the method findSubplot(info, point), or maybe more precise in the Method info.getPlotArea(). It seems like the maximum (internal) height of the plot area is 735.5390625. Although in fact it is larger. This leads to the fact that findSubplot(info, point) does ...

Re: How to fix the X axis As Integer ?

Your Integer problem can be solved like this:

NumberAxis axis = new NumberAxis();
axis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());

To label the ticks in a special way you can use the classes TickUnits, DateTickUnit and NumberTickUnit.
See the Javadoc for more information!

StandardCrosshairLabelGenerator

Hi,

Where can I find an example on how to use the new StandardCrosshairLabelGenerator?
XYPlot has a crosshair already. Is the new class Crosshair conflicting with that?

Best regards,
