Using DateAxis and XYBarRenderer with double values
Hi, I'm often using a DateAxis with a DefaultXYDataset. I store the long values representing the timestamps in the double array that is passed to DefaultXYDataset.addSeries(). With XYLineAndShapeRenderer this works really fine and I appreciate that DateAxis "understands" the doubles as dates. The pr...

Saving chart information to xml
Hi, I am looking for a way to save chart information, eg. title, chart type, formats, axis mapping, in short all properties necessary to rebuild a chart but the data. I'm thinking about an xml file, because serialization will probably be to fragile. I did not find anything similar in the JFreeChart ...

My fault
Think I've found the error. I was forgetting changing seconds to minutes and actually created the huge data load. But check the running demo prvided in my previous post anyway, just to see that there really is no problem with the remove code. I've thought for a long time that there should be some ki...

running code
Here is a running code sketch of what I'm doing. Just check it out for the remove thing. In the original libraries add and remove are class methods of the plot and have some more sophisticated code, but this is the essence. And this is why I think there can't be a problem with the removing. For the ...

this should not be the problem
I thank all of you for your prompt relies, because I already passed quite some time on this problem. But there is no problem with the loop. - The plot is created with an empty dataset (it needs one in the constructor) at first that I will never touch again. This makes for the 1 in the loop. - No ind...

XYPlot not releasing resources when setting dataset to null
I have a memory problem in my JFreeChart Application (a data viewer with variable data sources). I wrote a custom XYPlot that has an addDataset() and removeDataset() method, among others. removeDataset() sets the dataset in question to null. Now the app does two things: You can add and remove datase...

Code for multiline Axis label / text
Hi, to generate multiline axis labels I changed the following two methods (getTextBounds, drawRotatedString) in org.jfree.text.TextUtilities as it seemed more comfortable to me than trying to change the axis class to use textblocks (although this was a lot of work, too, despite the small result). "\...

Bug in XYDifferenceRenderer with inversed domain values
Hi, I created the following demo to demonstrate what I think is a bug in XYDifferenceRenderer. Every thing is ok, if at line 35 the code "inverse(time)" is inactive . If however, as in the demo, I inverse the x-axis values (before creating the dataset), the Renderer draws only lines. P.S. I added th...

different renderers for different plots
Every subplot needs its own renderer. The error was to set the renderer only once for CombinedDomainXYPlot and not for every subplot. At this time, I don't really see why CombindexDomainXYPlot should extend the plot class hierarchy at all, as every subplot is a complete and functionally independant ...

Equal legend items in CombinedRangeXYPlot (with running demo
In my CombinedRangeXYPlot all legend items are equal (to the series name of the last series added). I created the very simple demo below to reproduce what I mean. Either I have a really stupid error in my code that I can't see or it's a bug. Just try the demo. package bugfinder; import java.awt.Bord...

A little help for multiline axis labels
Hello, I'm changeing the TextUtilities Class to allow multiline Axis Labels with the \n line break character. I get the String to be drawn in multiple lines, the remaining problem is that the dataArea and plotArea size do not change, so the axis label is being drawn out of sight due to the shifting ...
