Rescale each channel to the new range as following:
new = data/old_range*new_range
- data : DataFrame
- data to be rescaled
- new_range : float | array | Series
- Maximal data value after rescaling
- old_range : float | array | Series
- Maximal data value before rescaling
(If old range is not given use the one specified in self.meta[‘_channels_’][‘$PnR’])
Deprecated!!!
