Display Datum Line Labels with Mouse Over
- From the modeling window or the Plot Browser > Datum Lines view, select the datum line to edit.
- 
                From the Entity Editor or the Plot Browser > Datum Lines
                    view, Label Location menu, select Mouse Over.
                HyperGraph hides datum line label except for the datum line currently selected in the panel.
- 
                Move the mouse over the datum line.
                HyperGraph displays the datum line label in a bubble help adjacent to, but under, the current mouse location. This is so the mouse cursor doesn’t obscure the text.
