====== MIN() Function ======

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

Usage:

''MIN(variable, options, threshold)'' - see below for description.

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

''MIN('INC1_AE', 5, 0)'' 

Get the minimum value for the selected period

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

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

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

Get the minimum 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 - Minimum value for current day |
|2 | WEEK - Minimum value for current week |
|3 | MONTH - Minimum value for current month |
|4 | YEAR - Minimum value for current year |
|5 | PERIOD - Minimum value for the selected range |
|6 | SLICE - Minimum value for the slice in the range (i.e. in a graph segment) |

The third option parameter allows you to set a threshold value other than 0.  This is useful when you are trying to calculate values in expressions such as MAX('var') - MIN('val') on data may be zero at midnight.  Leaving the third parameter at 0 would mean the expression would result in the maximum value.

===== Example =====
Get the miminum value of a variable for a day:

''MIN('delta0_kwh',1)''
