DevExtreme Angular - PivotGridDataSource - fields

Default Value: false

For example, a pivot grid row contains the following summary values split into three groups:

[ [1, 1, 1], [2, 2, 2], [3, 3, 3] ]

This row can be displayed differently depending on the allowCrossGroupCalculation option's value, provided that the running total is calculated by rows:

[ [1, 2, 3], [2, 4, 6], [3, 6, 9] ]    // allowCrossGroupCalculation: false
[ [1, 2, 3], [5, 7, 9], [12, 15, 18] ] // allowCrossGroupCalculation: true

allowExpandAll

Specifies whether a user can expand/collapse all items within the same column or row header level using the context menu.

Type:

Default Value: false

allowFiltering

Specifies whether a user can filter the field's values.

Type:

Default Value: false

When this option is set to true, the field's header in the field chooser and on the field panel is supplied with a filter icon. Clicking it invokes the header filter displaying all unique field values. A user applies filtering by selecting or clearing the selection of the values.

allowSorting

Specifies whether a user can change the field's sorting.

Type:

Default Value: false

When this option is set to true, clicking the field's header in the field chooser and on the field panel changes the sorting direction. An arrow icon in the header indicates the current sorting direction.

allowSortingBySummary

Specifies whether a user can sort the pivot grid by summary values instead of field values.

Type:

Default Value: false

When this option is set to true, a user can use a column header's or row header's context menu to sort the pivot grid by this column's or row's summary values.

area

Specifies the field's area.

Type:

Default Value: undefined

Accepted Values: undefined | 'column' | 'data' | 'filter' | 'row'

The field does not belong to any area if this option is undefined. However, the field's header is displayed in the field chooser, which enables the user to move this field to any area. In other cases, the field is displayed in the specified area.

Use the PivotGridArea enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Row, Column, Data, and Filter.

areaIndex

Specifies the field's order among the other fields in the same area. Corresponds to the field's order in the fields array by default.

Type:

Default Value: undefined

Type

Description

summaryProcess

The summary value calculation stage: "start", "calculate", or "finalize".

value

any

A value to be aggregated.

totalValue

any

The total summary value.

A summary value calculation is conducted in three stages: start, in which the totalValue is initialized, calculate, in which it is modified, and finalize, in which the totalValue is adjusted. To identify the current stage, check the value of the summaryProcess field that belongs to the function's parameter.

isMeasure

Specifies whether the field should be treated as a measure (a field providing data for calculation).

Type:

Default Value: undefined

There are no restrictions for rearranging fields in the areas using the field chooser. However, we recommend restricting measures to the data area by setting their isMeasure option to true. You can also set this option to false for a non-measure field to prohibit placing it in the data area.

name

Specifies the field's identifier.

Type:

Default Value: undefined

Set this option to refer to the field in code, for example, when changing field options.

runningTotal

Specifies whether to calculate the running total by rows or by columns.

Type:

Default Value: undefined

Accepted Values: 'column' | 'row'

For example, a pivot grid row contains the following summary values:

[ 3, 3, 3, 3, 3 ]

If the runningTotal option is set to "row", each value in this row is added to the previous value:

[ 3, 6, 9, 12, 15 ]

This also applies to columns if the runningTotal option is set to "column".

Use the PivotGridRunningTotalMode enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Row and Column.

selector

Specifies a function that combines the field's values into groups for the headers. Cannot be used with an XmlaStore or remote operations.

Type:

Default Value: undefined

This function is an alternative to the groupInterval option and should return a group name that corresponds to a data object. The function's parameter represents this data object. For example, the selector function in the following code groups birth dates by decades:

jQuery

JavaScript

$(function() {
    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        // ...
        fields: [{
            caption: "Birth Decade",
            area: "column",
            selector: function (data) {
                var birthDate = new Date(data.birthDate);
                return Math.floor(birthDate.getFullYear() / 10) * 10;
            }
        }]
    });
});

Angular

TypeScript

import PivotGridDataSource from "devextreme/ui/pivot_grid/data_source";
// ...
export class AppComponent {
    pivotGridDataSource: PivotGridDataSource;
    constructor() {
        this.pivotGridDataSource = new PivotGridDataSource({
            // ...
            fields: [{
                caption: "Birth Decade",
                area: "column",
                selector: function (data) {
                    let birthDate = new Date(data.birthDate);
                    return Math.floor(birthDate.getFullYear() / 10) * 10;
                }
            }]
        });
    }
}

ASP.NET MVC Controls

Razor C#

@(Html.DevExtreme().PivotGrid()
    .DataSource(ds => ds
        // ...
        .Fields(fields => {
            fields.Add()
                .Caption("Birth Decade")
                .Area(PivotGridArea.Column)
                .Selector("groupByDecade")
        })
    )

    function groupByDecade (data) {
        var birthDate = new Date(data.birthDate);
        return Math.floor(birthDate.getFullYear() / 10) * 10;
    }
</script>

Another example: a selector that places values below and over 1000 into different groups:

jQuery

JavaScript

$(function() {
    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        // ...
        fields: [{
            caption: "Amount",
            area: "column",
            selector: function (data) {
                return data.amount > 1000 ? "> 1000" : "< 1000"
            }
        }]
    });
});

Angular

TypeScript

import PivotGridDataSource from "devextreme/ui/pivot_grid/data_source";

                    return data.amount > 1000 ? "> 1000" : "< 1000"
                }
            }]
        });
    }
}

ASP.NET MVC Controls

Razor C#

@(Html.DevExtreme().PivotGrid()
    .DataSource(ds => ds
        // ...
        .Fields(fields => {
            fields.Add()
                .Caption("Amount")
                .Area(PivotGridArea.Column)
                .Selector("classifyValues")
        })
    )
)

<script type="text/javascript">
    function classifyValues (data) {
        return data.amount > 1000 ? "> 1000" : "< 1000"
    }
</script>

NOTE

The selector function cannot be used with remote operations. Instead, create a calculated data field on the server and bind a pivot grid field to it.

NOTE

The this keyword refers to the field's configuration.

showGrandTotals

Specifies whether to display the field's grand totals. Applies only if the field is in the data area.

Type:

Default Value: true

showTotals

Specifies whether to display the field's totals.

Type:

Default Value: true

NOTE

Setting this option to false hides the field's totals and summary values - only the grand totals are displayed. Set the showValues option to true to display summary values.

showValues

Specifies whether to display the field's summary values. Applies only if the field is in the data area. Inherits the showTotals' value by default.

Type:

Default Value: undefined

sortBy

Specifies how the field's values in the headers should be sorted.

Type:

Default Value: undefined

Accepted Values: 'displayText' | 'value' | 'none'

Dimension attributes have a value and a display text. For example, a "Month" attribute's display text can be "January", "February", ..., "December"; its values can be 1, 2, ..., 12. "January" is first when sorting by values, and "April" is first when sorting by display text. No sorting is applied when setting the sortBy option to "none".

Use the PivotGridSortBy enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: DisplayText, Value, and None.

sortBySummaryField

Sorts the field's values in the headers by the specified measure's summary values. Accepts the measure's name, caption, dataField, or index in the fields array.

Type:

Default Value: undefined

This and the sortBySummaryPath options can be used together to sort the field's values by a specific column's or row's summary values. If sortBySummaryPath is unspecified, the field's values are sorted by the specified measure's grand totals, as it is with the Region field's values in the following code:

jQuery

JavaScript

$(function() {
    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        // ...
        fields: [{
            caption: "Sales",
            dataField: "sales",
            area: "data",
            isMeasure: true,
            summaryType: "sum"
        }, {
            caption: "Region",
            dataField: "region",
            area: "row",
            sortBySummaryField: "Sales"
        },
        // ...
        ]
    });

    $("#pivotGridContainer").dxPivotGrid({
        dataSource: pivotGridDataSource
    });
});

                caption: "Sales",
                dataField: "sales",
                area: "data",
                isMeasure: true,
                summaryType: "sum"
            }, {
                caption: "Region",
                dataField: "region",
                area: "row",
                sortBySummaryField: "Sales"

sortBySummaryPath

Specifies a path to the column or row whose summary values should be used to sort the field's values in the headers.

Type:

Array<Number | String>

Default Value: undefined

This and the sortBySummaryField options are applied together. If this option is not specified, the field's values are sorted by the grand totals of the measure that sortBySummaryField specifies.

In the following example, geographic regions displayed in the row header are sorted by sales in the second quarter of 2015:

jQuery

JavaScript

$(function() {
    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        // ...
        fields: [{
            caption: "Sales",
            dataField: "sales",
            area: "data",
            isMeasure: true,
            summaryType: "sum"
        }, {
            caption: "Date",
            dataField: "date",
            dataType: "date",
            area: "column"
        }, {
            caption: "Region",
            dataField: "region",
            area: "row",
            sortBySummaryField: "Sales",
            sortBySummaryPath: [2015, 2]

sortOrder

Specifies the field values' sorting order.

Type:

Default Value: 'asc'

Accepted Values: 'asc' | 'desc'

Use the SortOrder enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Asc and Desc.

summaryDisplayMode

Specifies a predefined post-processing function. Does not apply when the calculateSummaryValue option is set.

Type:

Default Value: undefined

Post-processing functions allow you to perform additional calculations on each summary value and take into account neighboring cells' summary values.

The following list describes the available post-processing functions. These functions apply to one summary value at a time. This value is referred to as the "current value" in the descriptions.

"absoluteVariation"
Calculates the absolute difference between the current and previous value in a row. Starts from the second value in the row because the first does not have a previous value.
"percentVariation"
Same as the absolute variation, but the difference is calculated as a percentage.
"percentOfColumnTotal"
Calculates the current value as a percentage in one of the column's intermediate totals or the column's grand total when there are no expanded rows.
"percentOfRowTotal"
Calculates the current value as a percentage in one of the row's intermediate totals or the row's grand total when there are no expanded columns.
"percentOfColumnGrandTotal"
Calculates the current value as a percentage in the column's grand total.
"percentOfRowGrandTotal"
Calculates the current value as a percentage in the row's grand total.
"percentOfGrandTotal"
Calculates the current value as a percentage in the grand total of the entire pivot grid.

You can implement the capability to select the post-processing function at runtime using instructions from the Runtime Summary Type Selection article.

To specify a custom post-processing function, use the calculateSummaryValue option.

Use the PivotGridSummaryDisplayMode enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: AbsoluteVariation, PercentVariation, PercentOfColumnTotal, PercentOfRowTotal, PercentOfColumnGrandTotal, PercentOfRowGrandTotal, and PercentOfGrandTotal.

summaryType

Specifies how to aggregate the field's data. Cannot be used with an XmlaStore.

Type:

Default Value: 'count'

Accepted Values: 'avg' | 'count' | 'custom' | 'max' | 'min' | 'sum'

The summary type defines how to calculate the summary values that are displayed in the pivot grid's cells. The calculation is performed on a subset of facts that correspond to each field value in three areas (column, row, and filter).

The following summary types are supported:

"sum"
"min"
"max"
"avg"
"count"
"custom"
Applies a custom client-side aggregate function (calculateCustomSummary). Refer to Client-Side Data Aggregation for more information.
Any other type
Applies a custom server-side aggregate function. Refer to Server-Side Data Aggregation for more information.

Use the SummaryType enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Sum, Min, Max, Avg, Count, and Custom. To apply a custom server-side aggregate function, use a string overload instead.

You can implement the capability to select the summary type at runtime using instructions from the Runtime Summary Type Selection article.

visible

Specifies whether the field is visible in the pivot grid and field chooser.

Type:

Default Value: true

width

Specifies the field's width in pixels when the field is displayed in the pivot grid.

Type:

Default Value: undefined

wordWrapEnabled

Specifies whether text that does not fit into a header item should be wrapped.

Type:
