simple graphing package for experimental data

[junior aspirin]

does anyone know of a good graphing package that i can do this in:

i have some results from an experiment i did at uni, for this i need to plot these results on a graph, but i need to plot 2 different variables against each other and also it needs to be plotted on log scaled axis.

i tried doing this in calc but couldn't work out how to have one variable set for the x axis and another for the y axis.

any help is very welcome, be it a linux or windows program, even one you have to pay for, since it may be on my university's computers.

I'm at work now and only have Excel, so I will explain in Excel, although I'm very sure ooocalc can do this as well. Here goes:

Place your data in two columns in a worksheet
Go to Insert>Chart, pick the kind of chart you wish and press Next
On the next window, go to the TAB that sais Series. You will se a small window that lets you choose series. There, you pick the values you want on the Y axis.
A little bit lower, on the same Series TAB, you will have a field called "X axis", where you will choose the values from another column than in Series.
That's it.


As I said, calc can do this as well, and in a very similar manner, but I can post about that only when I get home.

There are almost limitless options.

Try gnumeric. It takes a little while to get used to, but the plotting capabilities are extremely customizable once you learn it.

You can use gnuplot. For example, suppose you want to plot this data:

1.1 18.0
4.4 40.0
8.3 89.0
21.1 90.0
44.0 249.7
50.0 409.4
112.1 703.0
211.0 1310.0
300.0 2300.0
433.0 3015.0

Suppose this data is in a file called "data". In the directory that contains this file, run gnuplot:

$ gnuplot
gnuplot> set logscale xy
gnuplot> set title "The Title"
gnuplot> plot "data" using 1:2 with linespoints

You can set many more attibutes and styles, and you can then output the plot in a variety of formats (postscript, jpeg, pdf, and many more). For example, I have attached a PNG version of the plot. It was create with these commands:

gnuplot> set logscale xy
gnuplot> set title "The Title"
gnuplot> plot "data" using 1:2 with linespoints
gnuplot> set terminal png
gnuplot> set output "data.png"
gnuplot> replot

You can install gnuplot from Synaptic, or from the command line with the command

sudo apt-get install gnuplot

There are multiple ways to do this. It should be possible in Calc. However, I regularly use gnumeric for this - you can select a scatterplot and select the data for the x and y axes. Once done, you can save it as a bitmapped or vector image.

oooo thanks, just been playing about with gnumeric, looks like just what im looking for, its come a long way since i last used it.

Using RLPlot which is available from the repos, very nice basic thingy with GUI... the equivalent of graphpad in windows! Highly customizable charts!
