I'm trying to put vertical dotted lines in a graph of a signal, to mark
the beginning and end of a window of the signal. Even solid light
colored lines would work fine. Is this possible? I have been completely
through the plot documentation and the graphics documentation with no
luck.

Thanks in advance for any help.

Something like that

function h = grinsvline(x)
% grinsvline(): insert vertical line in the current graph
h = line([x x], get(gca, 'YLim'), 'Color', [0 0 0]);
