Detailed Description

A set of parameters for /aggregate/histogram.

Performs a histogram calculation given a table, a column, and an interval function. The <member name="interval"> is used to produce bins of that size and the result, computed over the records falling within each bin, is returned. For each bin, the start value is inclusive, but the end value is exclusive–except for the very last bin for which the end value is also inclusive. The value returned for each bin is the number of records in it, except when a column name is provided as a value_column in <member name="options">. In this latter case the sum of the values corresponding to the value_column is used as the result instead.

Constructor & Destructor Documentation

kinetica.AggregateHistogramRequest.AggregateHistogramRequest ( )

inline

Constructs an AggregateHistogramRequest object with default parameters.

Definition at line 86 of file AggregateHistogram.cs.

kinetica.AggregateHistogramRequest.AggregateHistogramRequest	(	string	table_name,
		string	column_name,
		double	start,
		double	end,
		double	interval,
		IDictionary< string, string >	options = `null`
	)

inline

Constructs an AggregateHistogramRequest object with the specified parameters.

Parameters

table_name	Name of the table on which the operation will be performed. Must be an existing table or collection.
column_name	Name of a column or an expression of one or more column names over which the histogram will be calculated.
start	Lower end value of the histogram interval, inclusive.
end	Upper end value of the histogram interval, inclusive.
interval	The size of each bin within the start and end parameters.
options	Optional parameters. value_column The name of the column to use when calculating the bin values (values are summed). The column must be a numerical type (int, double, long, float).
