I have some data that is periodic, y=f(t) and the data is plotted as
plot, t, y The problem is I'd like t to plot phase angle rather than
time, the problem being the phase angle is between 0 and 1 and repeats.
Attempting to plot the data you just get a plot between 0 and 1, what I'd
like to be able to plot is each cycle of the data with it's phase angle.
Any ideas on how to get the plot axes right?
cheers,
S

You may want to try increasing the thickness of your line via the thick
keyword - I seem to remember having this problem a long time ago.

are you using the ARROW procedure? It sounds from your post that you are
using oplot to create the arrow...
-k.

Hope you are drawing your arrow in either data or normalize
coordinates. :-)
