Pyplot Simple

=============

A very simple pyplot where a list of numbers are plotted against their

index. Creates a straight line due to the rate of change being 1 for

both the X and Y axis. Use a format string (here, 'o-r') to set the

markers (circles), linestyle (solid line) and color (red).

plt.ylabel('some numbers')
