Before Origin 2018, if user customized a single point in line graph, the symbol failed show in legend.

If user customized a single point in line+symbol graph, the special point legend showed as line+symbol.

In Origin 2018, both are supported. For line+symbol plot, if you want the single point legend show as line+symbol as before, set @lsl=0.
