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).<\/p>\n

There are a bunch of Flash charting libraries, and I recently worked with a customer that was using “Open Flash Charts.<\/a>” 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.<\/p>\n

I started integrating these charting capabilities with Pentaho to see how the charts look. I was seeing some really great results. The integration was done via a fair amount of fancy Javascript\/Xaction sequence stuff but this integration did not require any custom Java application work. Just Pentaho .xactions and the basic open-flash-chart.swf. I might start looking at building a small little JSP library to help with some of this.<\/p>\n

The first one I built was a little pie chart, that has a nice animation (copied and pasted here without the dynamic .xaction stuff)<\/p>\n

The second one I built was this beautiful bar chart, comparing actuals and budgets.<\/p>\n

<\/object><\/p>\n

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.<\/p>\n

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.
