I understand that: set param; plot sin(t), cos(t) draws a circle, but assume
my sin and cos functions come from a 3-column data file. Can I make a
parametric plot from this data file?

Hi,
I am not quite sure what you mean by "sin and cos functions come from
a 3-column data file".
If you want to plot the cos of column 2 versus the sin of column one,
then
plot 'dat.dat' using (sin($1)):(cos($2)) with lines
should work. (You just have got to make sure that you set angle
properly.)
If this is not what you need, then I am lost. Could you, please,
clarify the question?
Best,
Zoltán
