I've been looking at all the examples and it seems the chart data source is always created by the Java code. I was hoping to some how come up with an expression that would give me a source appropriate for a Pie chart to hand to a drawable fieldd expression. I have some counts of groups I would like to show in the Header as a pie chart showing the distribution of items in the various groups.
I found some references to PieChartCollectorFunction in the pdf but I have not been able to find these class files in a jar, supporting jars, ext jars.
Anyone else done this? Did you write your own Collector function? Does everyone pretty much define the chart in the java? I would really much rather describe what data to collect and how to draw the chart in the report definition.
Feel free to let me know I'm a nut or an idiot. I'm ok with that.
How to generate chart data source on the fly?
