Re: plot saving

[John B. Thoo]

I use the following file: "/sw/share/octave/site/m/printfig.m".

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% to print to fig (xfig)
% JBT 2003/05/09


function printfig(filename)
% function printfig(filename)
% replot screen plot to a file
% inputs:
%   filename: string:
% no argument checking done - this means YOU mark!

  gset terminal fig color
  eval(sprintf("gset output '%s'", filename));
  replot
  #gset terminal x11
  closeplot
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

To print a plot to a file, I simply type

  > printfig ("filename.fig")

It works great.  And you can easily edit it to "printeps", &c.
