THere is a minor problem with rotated text which I will look into today and do some more testing. It depends on me getting the problems fixed and the release schedule of JFreeChart.

Create a defaultCategoryDataset... DefaultCategoryDataset defaultCategoryDataset = new DefaultCategoryDataset(); Then add your data to it defaultCategoryDataset.addValue(1.0, "rowKey", "colKey"); Create the chart... JFreeChart jFreeChart = ChartFactory.createLineChart("This is the title", "category ...

There is a problem with drawing strings with a new line character in them. One workaraund at the moment is to add subtitles for each line you wish to display.

There are a few feature requests for line breaks on the sourceforge tracker. I have supplied a patch for multi-line Axis titles and will hopefully have a patch for the tick labels soon.

Which may have some more information for you. Have a look at the axis.setRange() method(s).

This document is a little bit old - the best thing to do is to buy the latest developer's guide.

Alternatively, the guide should work with the now older JFreeChart 0.9.15 libraries.

If you are looking for a quick way to create charts have a look at the static methods

Using Swing - I need to query an Oracle database to get a recordset. The bar graph will be based on the recordset. Very simple graph. Does JFreeChart read the data from a file or can JFreeChart use the recordset directly? JFreeChart can read the data from the jdbc connection - have a look at org.jf...

the stack trace doesn't mention jfree chart - When you say you are using JFreeChart with portlets, how exactly are you using it?

E.g. which portlet are you using that includes jfreechart?

Does the system come up without 'using jfreechart'?
