Description

Adds an example of decimating data where we want to display a datetime axis. The idea is that the MinMaxDecimator takes the first and second column of the dataframe as x and y axes:

x = data[:, 0]
y = data[:, 1]

But it's possible to just set a different column as X axis marks. (Please correct me if my understanding isn't correct :)
