Now we see some simple features of the software we will use to visualize and plotting data.
Gnuplot
Gnuplot is a powerful (and free!) program for plotting functions and data, also fit and interpolation can be done. Gnuplot allows realizing 1D and 2D plots, as well as contour plot and heatmaps. If you are using the QM virtual machine the software is already installed.
Let'start creating a data file with random numbers e.g.:
$> cat > data.txt <<EOF >0 24 >1 33 >2 42 >3 24 EOF
