This worked for me:

```auto
lm = slicer.app.layoutManager()
pw0 = lm.plotWidget(0)
pv = pw0.plotView()
ch = pv.chart()
bb = ch.GetBackgroundBrush()
bb.SetColor(0,0,128)
ch.SetBackgroundBrush(bb)

```

I’d look along the same lines. In the chart MRML node, the plot view (subclass of ctkVTKChartView), and the VTK chart class. If there is such a function in said classes use that, if there isn’t, then it is probably not supported.
