Bar chart (report) static line

Ignition

Are you sure there's no errors in the console window?
configureChart was silently failing with your exact script because I didn't have a data key named average. Once I changed those lines, it worked:

def configureChart(data, chart):
	from org.jfree.chart.plot import ValueMarker
	marker = ValueMarker(4) #point on range axis to label
	label  = 'Avg:'
	marker.setLabel(label)
	chart.getPlot().addRangeMarker(marker)
	
	marker1 = ValueMarker(8) #point on range axis to label
	label  = 'Avg:'
	marker1.setLabel(label)
	chart.getPlot().addRangeMarker(marker1)
