Hi Jan,
You can emulate the same behavior (if there are no other docked panels to left, top, right or bottom) using fixed position in parent percentage units - for example:
chart.Location = new NPointL(0, 0);
chart.Size = new NSizeL(new NLength(100, NRelativeUnit.ParentPercentage), new NLength(100, NRelativeUnit.ParentPercentage));
That way the chart will occupy the whole control area (if it is under the root panel).
Hope this helps - let us know if you meet any problems or have any questions.
Best Regards,
