Please Help!! ploting with gnuplot

kelvin490 · 07-20-2011, 01:06 AM

I would like to ask if I have already plot a graph using gnuplot:

gnuplot> load '<ParadisDir>/inputs/gnuplot.defaults'
gnuplot> splot 'box.in' with lines, '0t0001' w lines

How to transform it to bmp file? (or other types of pictures?)

can I massively( and automatically) do this so that I'll have a set of bmp files (say, 100 of them) to make movie?

Thanks very much. All replies are welcome.

Did you even try looking at the Gnuplot documentation? The FAQ has this about making output files. If you just run "set terminal", it'll show you a list of output formats that can be used (JPEG is on the list, for example). There's probably info in there (or the reference manual) about batch scripting, so you can do things automatically.

Edit: Here's a simple example of a using Gnuplot in a shell script. All it does is plot sin(x) to files named "tmpn.jpg", where n is an integer from 1 to 10, from the for loop:

Code:

#!/bin/bash

for i in $(seq 1 10)
do
    gnuplot<<EOF
    set terminal jpeg
    set output "tmp$i.jpg"
    plot sin(x)
EOF
done

If you've not done shell scripting before, see this. The above example is called a here document.

Edit: If you want to make movies from a set of images, look at mencoder. Google will give you tutorials for doing this.
