Some of my plots contain vertical lines for alignment. To make sure the lines extend from the top to the bottom of the plot frame, I typically give those lines large values for +y and -y coordinates. This has an unfortunate side effect that the directive PlotRange->All now considers my line to be a part of the plot, and rescales the plot range to display it in its entirety. Is there a way to (a) either make PlotRange->All ignore this line somehow or (b) set the +y and -y coordinates of the line to match the current plot range?.. Thanks in advance to anyone who might clarify this... --Leo
