      2d12ratio0

      Divides the current row by the row that was 12 rows before it.

      Requires 2 dimensions (2d)

      Divides the current row by the row 12 rows before it.  (12ratio)

      Resets the row counter when dimension 1 changes. (0)

      Results of first 12 rows in the sequence are 0.

      Purpose

      Use this function to: 

      • Calculate monthly year on year figures

      Calculation

      When dimension 1 changes from Product1 to Product2, 2d12ratio0 for that row would reset to 0.

      When dimension 2 changes from Jan2020 to Jan2021, 2d12ratio0 for the row would be Jan2020/Jan2021

      Sample Result

      Parameters

      ParameterDescription
      DimensionsDiscrete field(s).    All fields must come from the same table.
      NameName to be displayed as Column Header in result grid
      Measure

      The field to be used in the post-function calculation.

      • Must be numeric if Function is anything other than COUNT.
      • Must come from same table as DIMENSIONS.
      • Supports Discrete or Continuous DataTypes.
      FunctionCOUNT / SUM / AVG / MIN / MAX / STDEV
      Post2d12ratio0
      Value

      Optional.   Filter to apply when evaluating FUNCTION.   Only records in the Filter Recordset will be included in the Function and Post-Function calculations.

      Must come from same table as DIMENSION/MEASURE or be linked to the Dimension table.

      Axis0 / 1.    Y-Axis to use when plotting graph.     Default = 0
      PlotY / N.   Specifies whether measure’s output column should be plotted on graph.  Default = Y
      ResolveOptional.   Resolve level for the measure.   If blank, Resolve = Dimension Table
      Series Type

      Default / Bar / Stacked Bar / Line / Spline / RangeLow / RangeHigh / CSLow / CSHigh / CSOpen / CSClose

      Determines the graph style for the measure.

      Usage Notes

      Requires 2 dimensions to calculate a ratio. 

      Example

      NOTE: Measure 1 is included purely for illustration. It is not necessary to include this measure for the calculation to work.


      Example use: Ratio in sales from one Year to the next (Year on Previous Year)

      e.g Product Sales for Jan 2021/ Product sales for Jan 2020


      Dimension: [transactions].[product_group], [transactions].[yearmonth]

      Measure 1

      • Name: = Count
      • Measure:  = [tranasctions].[cid]
      • Function: =count
      • Post: =
      • Value: =
      • Axis: =0
      • Plot:=Y
      • Resolve:=
      • Series Type:=Default
      • Popup:=Default
      • Prefix:=

      Measure 2

      • Name: = Year on Year
      • Measure:  = [transactions].[cid]
      • Function: = count
      • Post: = 2d12ratio0
      • Value: =
      • Axis: =0
      • Plot:=Y
      • Resolve:=
      • Series Type:=Default
      • Popup:=Default
      • Prefix:=
