Large_Sampled(Expr ,ValueIndex ,StartTime [,EndTime] [,SampleMethod] [,SampleInterval])<\/strong><\/p>\n Returns the nth largest value of the points in an expression over a range of time.<\/p>\n Expr:\u00a0<\/b>The expression whose values should be processed to find nth largest value. ValueIndex:\u00a0<\/b>The zero-based ordinal (n) of the value to return, i.e. use zero to return the largest value, use 1 to return the second largest value, etc. If the ordinal is greater than the number of values then an error will be returned. StartTime:\u00a0<\/b>The start time over which to produce the nth largest value. Note: You can use the Time() function to use a valid DateTime argument. EndTime:\u00a0<\/b>The end time over which to produce the nth largest value. Note: If not specified, it assumes the current time. You can use the Time() function to use a valid DateTime argument. SampleMethod:\u00a0<\/b>This optional parameter can be used to override the sample method which will be used for evaluating the expression (1st parameter). SampleInterval:\u00a0<\/b>This optional parameter can be used to override the sample interval which will be used for evaluating the expression (1st parameter).
