Pentaho Charting Extensions
Description
JFreeReport and JFreeChart aren't tightly integrated - that is, neither project "knows" that the other project exists. Pentaho has provided some objects that can be used within the Pentaho platform for integrating these two projects at a fairly high level. However, to make them work together, you need to have two cooperative pieces - A Data Collector Function, and a Chart Expression. The data collector function is responsible for creating a JFreeChart dataset type that JFreeChart understands and can use as input data to plot the chart. The Chart Expression is used to actually draw the chart based on the collected data.
Pentaho currently provides the following collectors:
