Re: [Help-glpk] Need help on interval planning constraint - Basic Bar and Line Graphs (GNU Plot) in GLPK/MathProg

[Nigel Galloway]

When your model is quick to execute then this would be a convinience. If your 
model takes several mins to run and you decide a different format is required 
for your graph to be clear then it could be annoying having to run the model 
again. Saving your result and pasting them into an Excel spreadsheet, then 
using its excellent graphic abilities is a good solution.

I think one of the glpk examples demonstrates generaring gnuplot commands as it 
output.
