[vtkusers] vtkChartXY - Initialize to a specific axis range

[Scott Fowler]

I'd like to create a vtkChartXY and initialize it with a specific axis range, however the axis range gets reset during the first Paint event.  Do I have to delay setting my axis ranges until after the Paint event, or is there a better way?

Code:
void createChart(vtkTable* data)
{
plot = new vtkPlotPoints;
plot->SetInput(data);
chart = new vtkChartXY;
contextView = new vtkContextView;
contextView->GetScene()->AddItem(chart);
chart->AddPlot(plot);
chart->GetAxis(0)->SetRange(200,400);
chart->GetAxis(1)->SetRange(2,7);
}

Paint gets called sometime after this method returns, causing my axis ranges to get reset.  How do I avoid this?
