Suppose we have phi(:,1) = x values, phi(:,2:ncols) = (ncols-1)
function values. An example code would be
plotcmd = "";
for k = 2 : ncols
plotcmd = sprintf ("%s, phi using 1:%d title \"-%d\" with lines", ...
plotcmd, k+1, k);
endfor
eval (sprintf ("gplot phi using 1:2 title \"function-1\" with lines%s",
plotcmd));
I hope this helps.
