Parameters

x
in, required
float The x-location to draw the vertical line. In the current x-axis units.

Keywords

label
in, optional
string The label to associate with this vertical line.

ylabel
in, optional
float The y-location to put the optional label text. ylabel is required if label is specified.

noshow
in, optional
boolean Don't immediately show the new vline. This is useful if you are stringing several vline calls together. It keeps the plotter from updating after each call and make the whole operation run faster. Simply call "show,/reshow" when you are ready to show the final result.
