Creating a Pie Chart with GNUPLOT

[Curtis-Van-Kampen]

I'm trying to create a pie chart using GNUPLOT based on
some infomation I received from this Newsgroup but I can't
seem to get it to work correctly. I think the problem has
to do with the way I am specifying the plot command. I'm
trying to using a data file called pie.out with the
following lines:

0 0
1.85e-04 1.0
0 0
5.55e-04 1.0
0 0
11.11e-04 1.0
0 0
18.52e-04 1.0
0 0
27.78e-04 1.0

My GNUPLOT input file looks like this:

set terminal pbm color;
set output "pie.ppm";
set title "Usage Statistics for MSPR1";

set polar
set size 0.721,1.0
set nozeroaxis
set noytics
set parametric
set data style line

plot t,1, "pie.out" 1

The plot comes out, but it doesn't have any "slices".

Any insight anyone could provide would be greatly
appreciated.

Thanks,

Curtis

Ooops. My fault! I figured it out.

I first wanted to send a mail, but whom?

First put a blank line between each pair of points you want to be
connected, like:

0 0
1.85e-04 1.0

0 0
5.55e-04 1.0

and so on.

Then use your file but modify the plot-command to

plot t,1, "pie.out" with lines

This works for me, allthough I cannot see any difference between the
two lines that build the boundaries. The angles are much to close to
each other (less than 0.5 degree).
