Start up the demo and open "TimeSeries Charts". There are a few demos of the PeriodAxis.
I don't have code at hand right now, but search the forum and use the JavaDoc. It's quite easy.

Re: DateAxis tick labels for regular intervals
To my knowledge, this can't be done with a DateAxis. But did you have a look at the PeriodAxis?

Re: ValueAxis FixedDimension bug
Hi!
I've created an entry in the bug-tracker: #3555275.
Could you be so kind and give some more details about the actual problem. What is the expected and the actual behaviour?
A demo program or a unit-test would be very helpful!
Thanks for reporting,

Re: Annotations using LogAxis
Hi! If you just want to show the same data on a logarithmic plot, you don't have to recalculate anything. Just exchange the axis, that's it. I would assume that all annotations work as expected, regardless which axis you use. If one doesn't, it's either a bug, or your expectations are wrong :) Pleas...

Re: Change BoxedLegend font, size, and/or color?
What is BoxedLegend? It's not a class that is part of JFreeChart.
JFreeChart provides a TextTitle or a LegendTitle for example. And those classes have various methods for changing fonts.

Re: exclude high brightness yellow series.
What I did is something like this: final Paint[] paintArray; // create default colors but modify some colors that are hard to see paintArray = ChartColor.createDefaultPaintArray(); paintArray[2] = new Color(0x00, 0xBB, 0x00); paintArray[3] = new Color(0xEE, 0xAA, 0x00); plot.setDrawingSupplier(new D...

Re: Dynamically add text to tooltip from another database co
You can easily create your own tooltips using a custom TooltipGenerator. What kind of text you output is up to you. You can read the text from a database, from a properties file, or use whatever you want. Generating that text, however, is not JFreeChart's job but yours.

Re: Problem Label Axis X: drawed out of graph
Hi!
The easiest solution/work-around to your problem is probably just setting some additional margin. You can use axis.setLowerMargin() resp. axis.setUpperMargin().
You could also try plot.setInsets().

Re: Alignment problem in vertical bars and category labels
A CategorySet is able to represent data in two-dimensions (like a table with rows and columns): +-+-+-+ |a|b|c| +-+-+-+ |d|e|f| +-+-+-+ |g|h|i| +-+-+-+ Your data just has a single row (or column): +-+-+-+ |a|b|c| +-+-+-+ | | | | +-+-+-+ | | | | +-+-+-+ But you are setting row and column keys in a wa...

Re: Alignment problem in vertical bars and category labels
Hi again! I know JasperReports but I've got close to no experience when it comes to using charts in it. Anyway, it's none of the visual properties of the chart that make it look like it does. It's your data that isn't used as supposed. Could you eventually try to change to code you just posted and s...

Re: Alignment problem in vertical bars and category labels
Hi! JFreeChart has nothing such as "Customizers". This seems to come from JasperReport and has nothing to do with your concrete problem. Your problem is, you are using the CategoryDataset in a wrong way. You use different series with a single item in each series, when you want to use a single series...

Re: mouse clicks in jfreechart !
Hi! There is so direct support for this in JFreeChart, as your chart is just an image in a browser which doesn't know anything about JFreeChart. So you have to find a solution on the client-side. You could use image maps to divide your chart into regions (I thinks JFreeChart has some basic support f...
