Good morning JJ,
I can help you find the JFreeChart, but I think you are going to be disappointed: the chart doesn’t contain normal datasets. The EasyChart munges large datasets before loading them, so the data you’ll be able to obtain may not be complete. With that caveat, here’s how I find the JFreeChart when I need it:
def findJFChart(src):
	"""IA's EasyChart and XYPlot components have their JFreeChart objects
	at different positions in the Container/Component hierarchy.  This
	helper function scans the hierarchy, given a container or component as
	a starting point, and returns a tuple containing the parent JFreeChartPanel
	and the targeted JFreeChart.
	Note:  The hierarchy is searched depth-first!
	"""
	from app.scriptmodule import findJFChart
	try:
		return (src, src.chart)
	except:
		pass
	try:
		for x in range(src.componentCount):
			try:
				return findJFChart(src.getComponent(x))
			except:
				pass
	except:
		pass
	raise ValueError, "Unable to Find a JFreeChart Instance"
The code makes one major assumption:  that the first property named “chart” that it encounters is the desired JFreeChart.  If that isn’t sufficient, you would need to add type-checking of that property.
Hope this helps!
Phil
