hanaml.M4Sampling.Rd
hanaml.M4Sampling a visalization method for time serie data
hanaml.M4Sampling(data, width)
DataFrame
Time series data whose 1st column is index and 2nd one is value.
integer
Sampling Rate. It is an indicator of how many pixels being in the picture.
Return the sampled DataFrame.
This algorithm takes a subset of the original data for visualiztion.
