Last Update: 5/9/2019
From Origin 2019b, by default, when Clip Data to Frame is checked on the Plot Details dialog, any plot symbol (including error bars) or associated data label that lies on the layer frame, is drawn in full. That is, any portion that lies outside the frame will not be clipped.
If you want to clip data system and associated label lying outside the frame, the old behavior in Origin 2019 and earlier versions, select menu Preferences: System Variables and set system variable @PEC to 1
