Hi Brian,
You can use view range inflate for this purpose - for example the following code applies a 10% margin on the right of the x axis:
NStandardScaleConfigurator scale = chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator as NStandardScaleConfigurator;
scale.ViewRangeInflateMode = ScaleViewRangeInflateMode.Absolute;
scale.InflateViewRangeEnd = true;
You can also take a look at the following example:
