Automated Graph Plotting

[krypto_wizard]

My python program spits lot of data. I take that data and plot graphs using OfficeOrg spredsheet. I want to automate this task as this takes so much of time. I have some questions.

1. which is the best graph plotting utility in linux. I know little about gnuplot. If you know any better tool without much learning curve please tell me.

2. I want to write a script such that my python code writes to a file, some graph utility like gnuplot takes that data from the file and I get my graph ready made. Do you think its possible ?

Any feedback regarding above is appreciated.

Thanks

Gnuplot is the way to go. There are a ton of tutorials available too. Here is an example file I have laying around to create a png for a plot of position versus time from a datafile called EXAMPLE5.1. Time is column 1, position is column 2

set terminal png
set output "q1plot.png"
set title "Plot of q1(t) for Problem 1"
set xlabel "Seconds"
set ylabel "Meters"
unset key
plot "EXAMPLE5.1" u 1:2 t "q1(t)" w lines

A quick google search will find many tutorials for more advanced stuff.

Well, since it is in python already. Why not use matplotlib ?
http://matplotlib.sourceforge.net/screenshots.html
It is great for graphs, you can view some source on that page too. Its a great plotlib.

Take a look at DataScene (http://www.cyber-wit.com). Its data monitoring feature might be useful to your applications.

Hopefully, they've found a solution in the last five years.
