Hi Rich,
The following code shows how to increase the automatic tick density (by default ticks are placed at about 25pt - this code sets this property to 15pt):
NLinearScaleConfigurator yScale = nChartControl1.Charts[0].Axis(StandardAxis.PrimaryY).ScaleConfigurator as NLinearScaleConfigurator;
yScale.MajorTickMode = MajorTickMode.AutoMinDistance;
yScale.MinTickDistance = new NLength(15, NGraphicsUnit.Point);
