ok i need a program like excell that will take in data from a txt file and put it in a spread sheet for graphing. BUT it also has to be able to handel things that are 1000x1000 so thats 1,000,000 points of data and be able to graph it. excell wont load one i just did thats 400x250

anyone know what will do this?


ALSO anyone know of a GOOD FREE Fortran compiler
 
g77 is the standard open-source fortran compiler. You'll need gcc as well as g77 is really a cross-compiler. (It's sometimes called f77 too)
What do you need to graph?

i need to graph the output of the program. which is an energy density diagram of the breakdown of spin resonance in non linear vibrational spin lattices

I would use something like gnuplot then. I know it can handle that amount of data. If it's just 2-d you could also try Grace. I've never put that much data into it, but I don't think it should have a problem with it.

well right now its a 1 D simulation. 2d will be going shortly and then there is 3d but that requires redoing teh fortran code alot. and i hate fortran

we are looking into getting IGOR Pro to do teh graphing but we dont have it yet

and im guessing i can just google "gnuplot" and "grace"??? im dooin this from win XP so iy has to work on that

does excel crash or something?

no it just doesnt load all teh data. says "file not loaded compleatly"

Excel only goes to colum "IV" which is only 230 across adn i need it to do 1000 across. or i will need it to

g77, gnuplot, and grace are all for *nix OS's. If you ever want to any serious scientific computing or visualization, you can't use Windows. You'll have to use a *nix variant.

damit i was afarid of that. i dont have linux installed on anything here. it can be done in wondows with "IGOR Pro" and a program called "IDL" o well just have to wait till teh school buys one of them then.

i guess i coudl set up linux on one of teh comps thats downstairs.....

I've never heard of either of those programs. All I can tell you is that 99% of real work is done on *nix OS's, and a lot of it with the programs I listed.

really? IGOR is a sweet program its used alot and really powerfull

you can check it out here http://www.wavemetrics.com/

Looks pretty cool. Although I think Grace can do most of that. I haven't run into anything yet that Grace or gnuplot couldn't do, so it seems kinda silly to buy software when GPL alternatives exist. I know a few people that use Windows software for plotting, but they will use something like IGOR. Nobody in their right mind would use Excel.
