[vtkusers] vtkBarChartActor - FontSize() won't work

[harshanand]

I am not sure why this happening, everything works well for vtkBarChartActor
except for FontSize(), it wont change no matter what value i give . I tried
changing color and it works, but not the fontsize. What might be the reason?

Code:

vtkSmartPointer<vtkBarChartActor> BarChartactor = 
vtkSmartPointer<vtkBarChartActor>::New();
		BarChartactor->SetInput(dataobject);
		BarChartactor->SetTitle("string");
                BarChartactor->GetTitleTextProperty()->SetColor(1,1,0);
                BarChartactor->GetTitleTextProperty()->SetFontSize(20);
