The data of X-Axis will be sent from 0 again after a while. At this moment, I need clear the trend on the display, like to redraw the trend curve. I know if I close the display and open it again the trend would start from fresh, but I would lose all the trend control properties changed online. How can I clear the trend display without closing the display window? ------------------------------------------------------------------------------------------ Split from How to delete trend with one trigger bit?.
