Well, that ended up being _way_ more involved than I figured it would be. But because I enjoyed myself:  
(Preemptive disclaimer: Don’t even think of trying to call in to support if this doesn’t work for you)

```auto
	from org.jfree.chart.renderer.xy import XYLineAndShapeRenderer
	from org.jfree.chart import LegendItem
	legend = chart.getLegend()
	plot = chart.getPlot()
	renderer = plot.getRenderer()
	
	class CustomRenderer(XYLineAndShapeRenderer):
		def getLegendItem(self, dataset, series):
			original = renderer.getLegendItem(dataset, series)
			new = LegendItem(
				original.getLabel(),
				original.getDescription(),
				original.getToolTipText(),
				"", #urlText
				original.getShape(),
				original.getLinePaint(), #set fill paint to line paint
				original.getOutlineStroke(),
				original.getOutlinePaint()
			)
			new.setSeriesIndex(series)
			new.setDatasetIndex(dataset)
			return new
		
		def getLegendItems(self):
			collection = XYLineAndShapeRenderer.getLegendItems(self)
			for ds in range(plot.getDatasetCount()):
				for series in range(plot.getSeriesCount()):
					legend = self.getLegendItem(ds, series)
					collection.add(legend)
			return collection
			
	newRenderer = CustomRenderer(True, False)
	newRenderer.setBaseSeriesVisibleInLegend(True)
	legend.setSources([newRenderer])

```
