Hi Thomas,
Most likely this is a problem with the axis fitting algorithm which we're currently researching. In general the algorithm will try to fit the chart and its axes inside the specified content area of the chart so that they don't go out of bounds, but probably there is a problem with the title measurement. You can turn off this feature by setting the Fit3DAxisContent property to false:
NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];
chart.Fit3DAxisContent = false;
We'll update you when we find / fix the problem.
Best Regards,
