the value to modify
the amount by which to modify the value
Optional t: anyif l is a Date, then this should be a
d3 time interval.
For backward compatibility with dc.js 2.0, it can also be the name of an interval, i.e.
'millis', 'second', 'minute', 'hour', 'day', 'week', 'month', or 'year'
Generated using TypeDoc
Arbitrary subtract one value from another.
If the value l is of type Date, subtracts r units from it. t becomes the unit. For example subtract(dt, 3, 'week') will subtract 3 (r = 3) weeks (t= 'week') from dt.
If l is of type numeric, t is ignored. In this case if r is of type string, it is assumed to be percentage (whether or not it includes %). For example subtract(30, 10) will give 20 and subtract(30, '10') will give 27.
They also generate strange results if l is a string.
