      2dratio0

      Divides the current row by the row that preceded it.

      Requires 2 dimensions (2d)

      Divides the current row by the previous row.   (ratio)

      Resets each time the first dimension changes. (0)

      Purpose

      Use this function to: 

      • Calculate sales ratios from one month to the next
      • Calculating price change ratios between transactions
      • Calculate ratio of current row to previous row

      Calculation

      First result in the sequence is 0 - i.e., when first dimension changes value, result for that row is 0

      eg.

      When dimension 1 changes from Product1 to Product2, 2dratio0 for that row resets to 0.

      When dimension 2 changes from Jan2020 to Feb2020, 2dratio0 for the row is Feb2020/Jan2020

      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
      Post2dratio0
      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.

      PopupDefault / None / Extended
      Prefix$ / £ / E / %

      Usage Notes

      Sort order is important - Ascending / descending Labels/Values 

      Example

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


      Example use: Calculate ratio of sales from one month to the next (Month on Previous Month)

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

      Measure 1

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

      Measure 2

      • Name: = Month on Month
      • Measure:  = [transactions].[cid]
      • Function: = count
      • Post: =2dratio0
      • Value: =
      • Axis: =0
      • Plot:=Y
      • Resolve:=
      • Series Type:=Default
      • Popup:=Default
      • Prefix:=
