I would like to make one small change to my code before I head off into the great white north. The spacing of the category labels is dead on.. But it would be better if there was a gap between them.. This code change will provide such a gap.. I really should have written a setter method for CATEGORY...

Simply go to the Patch section of the JFreeChart page. The id for this post is 1532660 the title is CategoryAxis Skip Labels and Tick Marks. Posted today, August 01, 2006..

the code is documented and has been tested. It seems to work pretty well.

:D Well it was hard.. I really wanted to do some fly fishing but instead I decided to stay home and work like crazy on a good solution to this problem.. I am happy to say, not as happy as I would have been with a 15 inch brook trout standing in the deep woods of Maine on the Canadian border :wink: b...

:roll: Yeah.. I noticed this.. I am very, very, new to JfreeChart so take these statements with a grain of salt.. I think that Jfree chart is doing what it should at least on my charts.. But I have not had much time to play with it. I am already off on the next task at work.. :? It looks like there ...

when we integrated my changes into our build we found something. if (plotState != null) { EntityCollection entities = plotState.getOwner().getEntityCollection(); was from the old CatAxis.. Sometime, I do not know why, the plotState owner will be null and in that case this will generate a null pointe...

may final solution, unless I have some time to make it better, has been posted to the jsaiz message. hope it helps..

After spending some time thinking about how to calculate N it came to me that this is futile and not the right solution. I tried various methods of adding up all the labels widths, or lengths, and comparing that to the axis length. Replacing the labels so they are centered. Several approaches. Non w...

I am continuing work on this in a different thread first started by Jsaiz titled “Skip Category Labels”. If, and when, I get this working I will post my solution there. And perhaps in this thread.
thanks ray

Okay.. I have it working.. All you have to do is call public CategoryAxisSkipLabels(String label, int interval) and pass in the interval.. The problem becomes knowing when to set this interval (at what point the labels start to overlap) and what to set it to (how many labels do I have space to actua...

Thanks I just found it a little while ago.. Not all the classes are in the API doc so that threw me off. I eventually went into the source and there it was.. for the record and to save someone else the effort.. Here are the import statements. import org.jfree.chart.axis.CategoryAxis; import org.jfre...

I need to skip labels in a category chart. There have been several request but no solutions. Does anyone have a solution? My categories are dates which can be in any arbitrary language or format. I can not use a time series chart because it does not support all the different chart types. I have no w...

I would like to try out this solution.. So I copied it down and included it into one of my projects and I can not seem to find RectangleEdge. Can you help me out with that.. I am running JFreeChart 1.0.1 Here are the imports I included into the Code package chartingTest; import org.jfree.chart.axis....
