Hi Hans,
You can achieve this by using the AfterSpace property of the axis anchor - for example:
NChart chart = nChartControl1.Charts[0];
NBarSeries bar = new NBarSeries();
bar.Values.Add(10);
bar.Values.Add(20);
bar.Values.Add(30);
chart.Series.Add(bar);
bar.DisplayOnAxis(StandardAxis.SecondaryY, true);
NDockAxisAnchor dockAnchor = (chart.Axis(StandardAxis.PrimaryY).Anchor as NDockAxisAnchor);
dockAnchor.AfterSpace = new NLength(15);
chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator.Title.Text = "Some Title";
chart.Axis(StandardAxis.SecondaryY).Anchor = new NDockAxisAnchor(AxisDockZone.FrontLeft);
chart.Axis(StandardAxis.SecondaryY).Visible = true;
Increases the distance between the axes to 15 points.
