Aggregation in JavaScript (ES5) Pivot Table control

This feature is applicable only for the relational data source.

End user can perform calculations over a group of values (exclusively for value fields bound in value axis) using the aggregation option. By default, values are added (summed) together. The other aggregation types are explained below.

The fields with data type such as number support all aggregation types mentioned below except for “CalculatedField”. The fields with data type such as string, date, datetime, boolean, etc., support “Count” and “DistinctCount” aggregation types alone.

Operator Description
Sum Displays the pivot table values with sum.
Product Displays the pivot table values with product.
Count Displays the pivot table values with count.
DistinctCount Displays the pivot table values with distinct count.
Min Displays the pivot table with minimum value.
Max Displays the pivot table with maximum value.
Avg Displays the pivot table values with average.
Index Displays the pivot table values with index.
PopulationStDev Displays the pivot table values with standard deviation of population.
SampleStDev Displays the pivot table values with sample standard deviation.
PopulationVar Displays the pivot table values with variance of population.
SampleVar Displays the pivot table values with sample variance.
RunningTotals Displays the pivot table values with running totals.
DifferenceFrom Displays the pivot table values with difference from the value of the base item in the base field.
PercentageOfDifferenceFrom Displays the pivot table values with percentage difference from the value of the base item in the base field.
PercentageOfGrandTotal Displays the pivot table values with percentage of grand total of all values.
PercentageOfColumnTotal Displays the pivot table values in each column with percentage of total values for the column.
PercentageOfRowTotal Displays the pivot table values in each row with percentage of total values for the row.
PercentageOfParentTotal Displays the pivot table values with percentage of total of all values based on selected field.
PercentageOfParentColumnTotal Displays the pivot table values with percentage of its parent total in each column.
PercentageOfParentRowTotal Displays the pivot table values with percentage of its parent total in each row.
CalculatedField Displays the pivot table with calculated field values. It allows user to create a new calculated field alone.

Assigning aggregation type for value fields through API

For each value field, the aggregation type can be set using the property type for each value fields through code-behind. Meanwhile, aggregation types like DifferenceFrom and PercentageOfDifferenceFrom can check for specific field of specific item using baseField and baseItem properties. Likewise, PercentageOfParentTotal type can for specific field using baseField property. For instance, the aggregation type DifferenceFrom would intake the specified field and its corresponding member as input and its value is compared across other members in the same field and also across different fields to formulate an appropriate output value.

It can be configured using type option for each value fields through code-behind. The settings required for summarize the value fields at initial rendering are:

  • type: It allows to set the aggregate type of the field.
  • baseField: It allows to set the base field to aggregate the values.
  • baseItem: It allows to set the base item to aggregate the values.

By default, the aggregation will be considered as Sum to the value fields which had number type and for the value fields which had non-number type such as string, date, datetime, boolean, etc., the aggregation type will be considered as Count. DifferenceFrom and PercentageOfDifferenceFrom can check for specific field of the specific item using baseField and baseItem. We can consider the PercentageOfParentTotal for specific field using baseField.

Modifying aggregation type for value fields at runtime

Aggregation types can be changed easily through UI at runtime. The value fields bound to grouping bar and field list appears with a dropdown icon which helps to select an appropriate aggregation type for the respective value field. On selection, the values in the pivot table will be changed dynamically.

Hiding aggregation type from button text

By default, in value axis each field would be displayed by its name and aggregation type together. To hide aggregation type and display field name alone, set the property showAggregationOnValueField in dataSourceSettings to false.

Hiding aggregation type icon from UI

By default, the icon to set aggregation type is enabled in the grouping bar. To disable this icon, set the property showValueTypeIcon in groupingBarSettings to false.

Icon to change the aggregation type can be hidden only in Grouping Bar but not in Field List at the moment.

Event

AggregateCellInfo

The event aggregateCellInfo triggers every time while rendering each value cell. This allows user to change the cell value and skip formatting if applied. It has following parameters:

  • fieldName - It holds current cell’s field name.
  • row - It holds current cell’s row value.
  • column - It holds current cell’s row value.
  • value - It holds value of current cell.
  • cellSets - It holds raw data for the aggregated value cell.
  • rowCellType - It holds row cell type value.
  • columnCellType - It holds column cell type value.
  • aggregateType - It holds aggregate type of the cell.
  • skipFormatting - boolean property, it allows to skip formatting if applied.
