3. Inverted CategoryAxis? jfree.orgHi all, I am working on Right-to-Left support for languages like hebrew/arabic etc. Inverting a ValueAxis seems an easy one-liner but there seems no way to invert the categoryAxis. I've searched the forum and found a similar post around 2004. http://www.jfree.org/forum/viewtopic.php?f=3&t=10814&p=31488&hilit=inverted#p31488 Answer from David back then was that it'd be implemented eventually. And he suggested to modify CategoryAxis source code. But ... |

7. Hiding some Tick lables in CategoryAxis jfree.orgHello All, Firstly, let me shower some appreciative comments on JFreeChart application as a whole. Its truely fantastic, esspecially the plethora of variety of graphs it allows to render is awesome!!. Meanwhile the difficulty I am facing is I have a set of dates which do not have specific interval in between (Ex: 09/12/04, 10/01/05, 12/01/05 etc). Since no Date related ... |
8. Adjusting Ticks on a CategoryAxis jfree.orgI'm displaying a 3DBarChart with a single category and many (100+) values. It appears that the the chart attempts to draw a tick label for every value and does so by drawing them very small. I haven't been able to figure out how to draw only a select few of those labels. Can anyone help? |

11. CategoryAxis.setInverted ?!? jfree.orgHi, I am working on a watefall-chart and to fully support the desired charts formating, I need to invert the category-axis. So the "big-bar" is not on the right-hand-side but on the left. Unfortunately the current JFreeChart version does not seem to support this. Is there a way I can do this without manually patching the current version? Chris |

14. CategoryAxis.setAxisLineVisible problem jfree.orgby florinmarcus Wed Jul 26, 2006 12:56 pm I have found the problem. That strange border is in fact a rangeMarker.

20. CategoryAxis tick labels. jfree.orgI'm having the problem where I have many categories plotted, and I need some way of filtering the tick labels that are shown. Right now, with 50 or more categories, the labels turn to ellipses since there is not enough room for them. Is it possible to only show selective tick labels on a CategoryAxis? |
21. new CategoryAxis call locks thread. jfree.orgI'm creating a new axis: CategoryAxis categoryAxis = new CategoryAxis("blah"); ...and the call to this simply locks up the thread.

22. categoryAxis skip tickUnits jfree.orgThere's a patch in SourceForge somewhere to make the CategoryAxis skip some labels. I've never put it into JFreeChart, because I think it is a misuse to have the CategoryAxis hide some labels (if you can guess the labels in between, then you have a value scale and should be using XYPlot and a NumberAxis). But you can use the patch ... |
23. CategoryAxis labels overlapping jfree.orgI have a BarChart with a DefaultCategoryDataset and a CategoryAxis for domain axis. The dataset contains several thousand values so the labels on the category axis are overlapping. Is there a way to display only part of the labels so they can be read? I think what is needed is similar to TimeSeries chart where the axis labels are self adjusting. ... |

25. CategoryAxis Bug v1.0.11 jfree.orgCategoryAxis Bug v1.0.11 by svicheck Fri Oct 24, 2008 4:01 pm I discovered this in CategoryAxis from the HEAD branch of SVN but it most likely has been around for a while. When CategoryAxis reserves space for the axis labels it calls refreshTicks() passing a graphics context with its font specifically set to getTickLabelFont(). This calculates the the label sizes ... |
26. Multiple CategoryAxis in a CombinedDomainCategoryPlot jfree.orgHi, Firstly, is it possible to have multiple CategoryAxis objects set to a CombinedDomainCategoryPlot object?

Code: Select all CombinedDomainCategoryPlot plot = new ... |
27. Mark ticks in CategoryAxis jfree.orgTick mark rendering on the CategoryAxis has never been implemented. It would be easy enough to write the code to put tick marks in the middle of each category (in fact I did that just now and committed it to Subversion for inclusion in the upcoming 1.0.13 release). It is a little trickier to provide the option of putting tick marks ... |
