On first inspection it looks like CategoryTextAnnotation can only be used to add text into a plot? I guess I could use that to place the text directly on the line but more ideal would be to have a proper legend at the side, but inside the graph.

Any demo code for StandardCategorySeriesLabelGenerator?

This is the sort of thing I need:

If there is no way to add in the legend in like that on a CategoryPlot (I can get it to appear outside of the chart, but need it inside really), is there any way to recreate that chart using an XYPlot?

XYTitleAnnotation

I need to add a legend inside my CategoryPlot chart. On searching the forum this experimental class was the only thing I could find for doing this sort of thing but is there any way to use it with a CategoryPlot?

Ah! Sorry, I see what I was doing. I thought I was meant to draw the second line as vertical, rather than horizontal. That makes sense now.

Thanks very much for your help!

The second series was meant to be vertical. The graph I am trying to achieve is something like this: http://i7.photobucket.com/albums/y260/-alsvartr-/fpdftb.gif My understanding from the earlier posts in this thread was that you were suggesting drawing the curve as the first series, and drawing the ...

Richard, I am trying to use the method you suggested here. I have had success drawing the line underneath the curve, but I cannot get it to fill in area between the two datasets. I have used XYDifferenceRenderer as suggested but it does not work! Here is some code giving a basic example: package mai...

Just to say, I managed to solve this (I think!) by initially, when all values in my dataset are zero, setting the NumberAxis with setAutoRange(false). Only once I edit the dataset to add in values do I use setAutoRange(true).

Category plot with error bars

I need a category plot displaying only a few data items which must be updatable, looking like this: http://i7.photobucket.com/albums/y260/-alsvartr-/errorbars.jpg I created the above chart using DefaultStatisticalCategoryDataset which just about works perfectly. However, I cannot figure out a suitab...

Aha, figured this out, by using a ValueMarker. Seems to be the best way!

Re: Plotting more than one distribution

If you want to learn Ant, you can find tutorials online. However, almost every open source project has their API documentation online. JFreeChart is no exception with its JavaDocs . So the on-line API doc and what you get from Ant is the same thing? I've been using the on-line API so far. I was jus...

Re: Plotting more than one distribution

Try to post all related questions in the same thread. Create the two datasets and then add the series from one of the datasets to the other. Not exactly fancy but quick. The other option would be to sample the distribution functions manually en masse and populate a single dataset. Really sorry abou...

Re: Plotting more than one distribution

Thanks very much for your replies! If you want to draw integrals as you did in JFreeChart and Statistics , you will want to keep each distribution in separate datasets. By using the first method you mentioned ("Create the two datasets and then add the series from one of the datasets to the other")? ...
