I have been attempting to created a stacked line chart using the ‘Chart’ component, using the ‘configureChart’ extension function. But I am unable to get it to work. The extension function code is as follows:
from org.jfree.chart.renderer.xy import StackedXYAreaRenderer
plot = chart.getPlot()
renderer = plot.getRenderer()
plot.setRenderer(StackedXYAreaRenderer())
Which then throws the following ClassCastException error which I am unable to fix:
15:57:20.892 [AWT-EventQueue-2] ERROR Vision.ClassicChart - Error invoking extension method.
org.python.core.PyException: Traceback (most recent call last):
