I'm working with version 5.03!
The implemented zoom stretches the diagram to the left and lower side and the cursor is not left on the coordinate in the diagram. Is it possible to implement a Zoom-Function that zooms on a specified coordinate in the diagram? (with all autoscroll,...)
So that the cursor is on the same coordinate all the time!?

The following Code on a Mousewheel-Event works correctly, when the area is scrollable, but not, when there are no scrollbars! Then only the standard zoom behaviour works adequate!

"Diagramview ctl_modelChart;"

Point p=ctl_modelChart.PointToClient(Cursor.Position);
if (!ctl_modelChart.Bounds.Contains(p))

return;
PointF oldcurpos = ctl_modelChart.ClientToDoc(p);

if (e.Delta < 0)
{

ctl_modelChart.ZoomOut();
}
else
{

ctl_modelChart.ZoomIn();
}


PointF newcurpos = ctl_modelChart.ClientToDoc(ctl_modelChart.PointToClient(Cursor.Position));

float diffx = (oldcurpos.X - newcurpos.X);
float diffy = (oldcurpos.Y - newcurpos.Y);

if (ctl_modelChart.HScrollBar.Visible)
   ctl_modelChart.ScrollX = ctl_modelChart.ScrollX +
     diffx < 0 ? 0 : ctl_modelChart.ScrollX + diffx;

if (ctl_modelChart.VScrollBar.Visible)
ctl_modelChart.ScrollY = ctl_modelChart.ScrollY +
      diffy < 0 ? 0 : ctl_modelChart.ScrollY + diffy;

Thanks!
