In lib/plotutil.py, the functions plot and plot_line has many elements in common. Try to merge plot_line into plot. Use a flag (or any other method) to determine whether a function is to be plotted or two lists of x and y has to be plotted and do both the stuff in the same function. In this way the repeated code can be removed.
