How you can redraw plots

There are two ways of graphing any data in a plot:

1. By waiting for data change occurs and only then plotting
2. By constantly calling a method and polling for data

Conclsions

1. If you pass a list of n elements then the x axis range will be 0 to n
2. A single plot space can have multiple line graphs painted on it all you have to do is to call .plot() method for a new instance
