Hello Ahmed,
In order to add the AxisX scrollbar, you have to enable
the zoom. Please refer to the following sample code that shows how to set the
zoom for the three first points of 20 points:
//Set initial view from point 1 to 3
chart1.AxisX.Zoom(1, 3);
//Activate the initial zoom
chart1.UpdateSizeNow();
I hope this helps,
