Example: 1D graph (better looking)

This is block of code to plot a presentable 1D graph

This is very short block of code to plot a presentable 1D graph. This can be incorporated in your code to make graphs, more presentable. The usage of subscript, superscript, symbols & multi-lines in titles are demostrated in this code. The same idea can be used in labels of the axes, and legends as well.
