# 2dcumul

2dcumul

### Successively adds the current row to the previous row, and restarts the count each time dimension 1 changes

Requires 2 dimensions in order to accumulate (2d)

Successively adds current row to the previous row’s accumulation. (cumul)

Restarts the accumulation each time dimension 1 changes

e.g.

Dimension1 = Product { [Product1], [Product2]…}

Dimension2 = Quarter { [Q1], [Q2], [Q3]…}

Measure = [Sum of Sales]

### Parameters

| Parameter | Description |
| --- | --- |
| Dimensions | Discrete field(s). All fields must come from the same table. |
| Name | Name 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. |
| Function | COUNT / SUM / AVG / MIN / MAX / STDEV |
| Post | 2dcumul |
| 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. |
| Axis | 0 / 1. Y-Axis to use when plotting graph. Default = 0 |
| Plot | Y / N. Specifies whether measure’s output column should be plotted on graph. Default = Y |
| Resolve | Optional. 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. |
| Popup | Default / None / Extended |
| Prefix | $ / £ / E / % |

### Usage Notes

Cumulative data is always dependant on row sort order.

2dcumul is also dependent on the order in which dimensions are specified.

### Example

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

Example use: Calculating the running sales total, grouped by quarter and product

#### Dimension:[transactions].[yearqtr], [transactions].[2dcumul]

| #### Measure 1 - Name: = Sum Sales - Measure: = transactions.castprice - Function: =Sum - Post: = - Value: = - Axis: =0 - Plot:=Y - Resolve:= - Series Type:=Default - Popup:=Default - Prefix:= | #### Measure 2 - Name: =2dcumul - Measure: = transactions.castprice - Function: = sum - Post: = 2dcumul - Value: = - Axis: =0 - Plot:=Y - Resolve:= - Series Type:=Default - Popup:=Default - Prefix:= |
