====== MAX() Function ======

The MAX() function can be used in a variety of ways to get the maximum value of a variable.  

Usage:

''MAX(variable, options, [days])'' - see below for description.

===== Generic Variables (per device type) =====

''MAX('INC1_AE'), 5'' 

Get the maximum value for the selected period

===== Device - Specific Variables =====

For device specific variables use a . to separate the device name:

''MAX('My Device.My Value',1)''

Get the maximum value of the variable for the current day.

===== Option Parameters =====

The second parameter, [options] is a number and can be any of the following

|0 | latest value (Default) |
|1 | DAY - Maximum value for current day |
|2 | WEEK - Maximum value for current week |
|3 | MONTH - Maximum value for current month |
|4 | YEAR - Maximum value for current year |
|5 | PERIOD - Maximum value for the selected range |
|6 | SLICE - Maximum value for the slice in the range (i.e. in a graph segment) |

The third optional parameter lets you shift the range by a specific amount of days - i.e. a value of 7 will calculate the maximum value for the selected period 1 week ago.
===== Example =====
Get the Maximum value of a variable for a day:

''MAX('delta0_kwh',1)''
