Modifier is a script that lets you reuse your modifiers from dashboard and apply them the the whole csv data file. Suppose you want to smooth charts. You first write coffeescript code that smooths your data in dashboard and then apply the same code to smooth the whole data in the same way.

How to use:

Usage: coffee ./modifier.coffee -input [csv] -output [csv] -modifier [coffee]
Options:
--input Your csv data file in accepted format [required]
--output The name of result csv file [required]
--modifier The file with coffeescript modification code [required]

A modification code sample:

el[3] = el[3] *1.5#x
el[4] = el[4] *1.5#y
el[5] = el[5] *1.5#zwhen4#gyroscope
el[3] = el[3] *1.2#x
el[4] = el[4] *1.2#y
el[5] = el[5] *1.2#zwhen'geo'#geodata
el[9] = el[9] /2#speedreturn data
