Using these settings I would expect the graph axis to have steps at 350, 405, 460, 515 570, 625.  Unfortunately this is not the case.  What do I need to do to make this happen?

chart.Axis(StandardAxis.PrimaryY).View = new NRangeAxisView(new NRange1DD(350, 625), true, true);
((NStandardScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator).MajorTickMode = MajorTickMode.CustomStep;
((NLinearScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator).CustomStep = 55;
((NLinearScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator).RoundToTickMax = false;
((NLinearScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator).RoundToTickMin = false;

This is the result.
