Display X Value as Label on Easy Chart

Should the label creating code not live in configureChart routine?

It absolutely should, and I think you're making it far more complicated than it needs to be.

See:

Formatting chart labels in reporting V7.9?

Yeah, So I was only providing an example, to show a simple solution for what it would look like. Probably should have just not been lazy and actually included a detailed explanation as well. So for this generator, the MessageFormat ArgumentIndex values correspond to the following: 0 = series name 1 = domain or X-Axis Value 2 = range or Y-Axis Value The number between the ‘{}’ tells the generator which value/s to use in the label output. You can include text that will be t…

I understand that post is from quite a while ago, and different version of the software, but it should still apply.

Try this code:

def configureChart(self, chart):
	from org.jfree.chart.labels import StandardXYItemLabelGenerator
	from java.text import DateFormat
	from java.text import NumberFormat
	
	renderer = chart.plot.renderer
	xFormat = DateFormat.getDateTimeInstance()
	yFormat = NumberFormat.getNumberInstance()
	renderer.setItemLabelGenerator(StandardXYItemLabelGenerator('{1}',xFormat,yFormat))
	renderer.setBaseItemLabelsVisible(True)

Note, it won't take many data points for this to become unreadable. You can of course provide a more granular format for the date format.
