I’ve worked on several customer dashboards and found the charting in Pentaho to be pretty good in a lot of circumstances, but lacking for a lot of circumstances. In particular, certain shading, animations, etc aren’t supported in Pentaho charts (based on JFreeChart).
There are a bunch of Flash charting libraries, and I recently worked with a customer that was using “Open Flash Charts.” I helped them get Mondrian data streaming through to this flash charting engine. I was surprised to find that the library is open source, and is moving to LGPL (away from GPL) to ensure that people feel comfortable embedding it in their applications.
The first one I built was a little pie chart, that has a nice animation (copied and pasted here without the dynamic .xaction stuff)
The second one I built was this beautiful bar chart, comparing actuals and budgets.
In all cases, if you’re needing some “more” from Pentaho in terms of data visualization, don’t hesitate to be in touch. This flash chart is the latest in a series of dashboards that Bayon has been building for customers.
UPDATE: I built another one for a new customer, and changed the data labels for presentation here. Having a grand time with open flash chart. This chart below is the output of an MDX query to Mondrian. The one is the metric ( a base measure ) the other is a running total.
