By default Clip Data to Frame is checked so data points outside layer frame are not be plotted.

But this causes issue such as symbol, error bar and data labels on the edge of layer frame will show in half, error bar show in half or not showing. 

We improved it so that if the center of the point is around the edge of layer frame, show the data point, error bar and data label in full. 

System variable @PEC=0 by default. Set it to 1 to roll back to old behavior of strict clipping.
