Hi Frank,
Yes - you should switch the chart in bounds mode stretch and optionally use docking - for example:
NChart chart = nChartControl1.Charts[0];
chart.BoundsMode = BoundsMode.Stretch;
chart.Dock = DockStyle.Fill;
chart.Margins = new NMarginsL(5, 5, 5, 5);
will tell the chart to occupy the whole area of its containing panel, minus 5 points from the sides.
Hope this helps - let us know if you meet any problems.
Best Regards,
