gr_edit to add xline / vline

[patricio cuaron]

Hello. Does someone know how to add xline or vline to a graph after the fact? The recorder is not very helpful, as it generates code that doesn't run from the console.

. sysuse auto
(1978 automobile data)

. scatter price mpg

. gr_edit .plotregion1.declare_xyline .gridline_g.new 25, ordinate(x) plotregion(`.plotregion1.objkey') style(default)
option plotregion() required
r(198);

. gr_edit .plotregion1.declare_xyline .gridline_g.new 25, ordinate(x) plotregion(1) style(default)
invalid plotregion for xline or yline
r(198);

. gr_edit .plotregion1.declare_xyline .gridline_g.new 25, ordinate(x) plotregion(plotregion1) style(default)
invalid plotregion for xline or yline
r(198);

See addplot from SSC that will allow you to edit an already created graph using standard options.
