2D plots

In this section we are going to plot several data. First create a new directory in your home that will contain the data files we are going to use. Open a terminal and change into your home directory, if you are not already there. Create the new directory and name it as you wish, e.g.:

$ cd
$ mkdir data_directory

Change into that newly created directory. Open a webbrowser and download the data files we are going to use to the data directory you've just created. Alternatively you can stay in the terminal and use the program wget that makes it possible to download webcontent to your working directory

$ wget URL

The data we will use is available under the following URLs:
http://www.tbi.univie.ac.at/~ronny/Leere/sb1/data.1
http://www.tbi.univie.ac.at/~ronny/Leere/sb1/data.2
http://www.tbi.univie.ac.at/~ronny/Leere/sb1/data.3
http://www.tbi.univie.ac.at/~ronny/Leere/sb1/data.4
http://www.tbi.univie.ac.at/~ronny/Leere/sb1/data.5

After downloading all data, we are prepared to use the programs grace and gnuplot to plot the provided data.

Before plotting anything with one of the following programs, take some time to have a look inside the data files to ensure that the residing data fits your expectations.

Hint: Use

$ head -n 20 datafile

to see the first 20 lines...
