I have a chart component that I’ve configured a category chart on. The renderer is set to stacked bar. By default the bars have a gradient on them. I’d like to remove the gradient and just have flat colors. From what I’ve found searching for removing the gradient from a jfreechart categoryplot it looks like I need to set the barPainter to the StandardBarPainter style but I’m not entirely sure how to do that. Has anyone done this before?

Put this in the configureChart extension function.

```auto
	from org.jfree.chart.renderer.category import StandardBarPainter

	plot = chart.getPlot()
	plot.getRenderer().setBarPainter(StandardBarPainter())

```

Thank you! Just in case anyone else needs it, I added one more line to remove the shadow.

```auto
	from org.jfree.chart.renderer.category import StandardBarPainter

	plot = chart.getPlot()
	renderer = plot.getRenderer()
	renderer.setBarPainter(StandardBarPainter())
	renderer.setShadowVisible(0)

```
