Grouping bar in Vue Pivotview component

1 Mar 202424 minutes to read

To learn about the Grouping Bar feature in the Vue Pivot Table component, you can watch this video.

The Grouping Bar option in pivot table automatically populates fields from the bound data source and allows end users to drag fields between different axes such as columns, rows, values, and filters, and create pivot table at runtime. It can be enabled by setting the showGroupingBar property in pivot table to true.

Similar to Field List, Grouping Bar UI also comes with basic interactions like,

Re-arranging fields through drag-and-drop operation between row, column, value and filter axes.
Remove fields from the existing report using remove icon.
Filtering members of specific fields using filter icon.
Sorting members of specific fields using sort icon.

To use grouping bar, You need to inject the GroupingBar module in pivot table.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        expandAll: false,
        allowLabelFilter: true,
        allowValueFilter: true,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        formatSettings: [{ name: 'Amount', format: 'C0' }],
        filters: []
      },
      height: 350,
      showGroupingBar: true
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

The grouping bar provides some additional options to customize it’s UI using groupingBarSettings property.

Show or hide all filter icon

The Grouping Bar has an option to filter members of particular fields at runtime in pivot table. In-order to filter members in a field, click the filter icon and check/uncheck members that needs to be displayed. By default, filter icon besides each field is enabled in the grouping bar. To disable the filter icon, set the property showFilterIcon in groupingBarSettings to false.

By default, the filter icon is enabled in the grouping bar.

Disable all fields from dragging

The Grouping Bar has an option to drag-and-drop fields between row, column, value and filter axes in-order to change report at runtime. By default, all fields are available for drag-and-drop operation in the grouping bar. To disable these fields, set the property allowDragAndDrop in groupingBarSettings to false. This will prevent end user from changing the current report.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar" :groupingBarSettings="groupingBarSettings"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        expandAll: false,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],

        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

Disable specific field from dragging

To disable dragging for a specific button, set the property allowDragAndDrop to false to the corresponding field in dataSourceSettings.

In the below sample, the drag and drop of the fields “Year” and “Products” have been restricted.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        columns: [{ name: 'Year', caption: 'Production Year', allowDragAndDrop: false }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],

        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

Remove specific field(s) from displaying

When a report is bound to the pivot table, fields will be automatically populated within the Grouping Bar. In this case, you can also prevent specific fields from being displayed. To do so, set the appropriate field name(s) in the excludeFields property of dataSourceSettings.

The excludeFields property setting will be reflected in the field list UI as well, and for more information, see this link.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        formatSettings: [{ name: 'Amount', format: 'C0' }],
        excludeFields:['In_Stock'],
        filters: []
      },
      height: 350,
      showGroupingBar: true
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

Changing aggregation type of value fields at runtime

End user can perform calculations over a group of values using the aggregation option. The value fields bound to the field list, appears with a dropdown icon, helps to select an appropriate aggregation type at runtime. On selection, the values in the Pivot Table will be changed dynamically. 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. To know more about aggregation, refer here.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar" :groupingBarSettings="groupingBarSettings"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        expandAll: false,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        formatSettings: [{ name: 'Amount', format: 'C0' }],
        filters: []
      },
      height: 350,
      showGroupingBar: true,
      groupingBarSettings: {
          showValueTypeIcon: false
      }
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

To disable the dropdown icon for a specific button, set the property showValueTypeIcon to false to the corresponding field in dataSourceSettings.

In the below sample, the dropdown icon of field “Sold” is hidden.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold', showValueTypeIcon: false }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        formatSettings: [{ name: 'Amount', format: 'C0' }],
        filters: []
      },
      height: 350,
      showGroupingBar: true,
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

The property showFilterIcon, showSortIcon, showValueTypeIcon and allowDragAndDrop in fields of dataSourceSettings are applicable for both grouping bar and field list.

Show values button

During runtime, the Values button in the grouping bar can be moved to a different position (i.e., different index) among other fields in the column or row axis. To enable the Values button, set the showValuesButton property to true.

This support is only available for relational data sources.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        expandAll: true,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        filters: []
      },
      height: 350,
      showGroupingBar: true,
      showValuesButton: true,
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

Event

OnFieldDropped

The eventonFieldDropped fires whenever a field is dropped in an axis. It has following parameters - droppedAxis, droppedField and dataSourceSettings. In this illustration, we have modified the droppedField caption through this event at runtime.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar" :onFieldDropped="onFieldDropped"> </ejs-pivotview>
    </div>
</template>

<script>
import Vue from "vue";
import { PivotViewPlugin, GroupingBar, FieldDroppedEventArgs } from "@syncfusion/ej2-vue-pivotview";
import { pivotData } from './pivotData.js';

Vue.use(PivotViewPlugin);

export default {
  data () {
    return {
      dataSourceSettings: {
        dataSource: pivotData,
        expandAll: false,
        columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
        values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
        rows: [{ name: 'Country' }, { name: 'Products' }],
        formatSettings: [{ name: 'Amount', format: 'C0' }],
        filters: []
      },
      height: 350,
      showGroupingBar: true
    }
  },
  provide: {
        pivotview: [GroupingBar]
    }
  methods: {
    onFieldDropped: function(args: FieldDroppedEventArgs) {
        //Triggers, whenever field is dropped in an axis.
        args.droppedField.caption = args.droppedField.name + " --> " + args.droppedAxis;
    },
  }
}
</script>
<style>
@import "@syncfusion/ej2-vue-pivotview/styles/material.css";
</style>

FieldDragStart

The event fieldDragStart fires whenever a field drag starts from its axis. It allows the user to restrict the drag operation based on its parameters. It has the following parameters

fieldName: It holds the name of the appropriate field.
fieldItem: It holds the complete definition of the appropriate field mentioned in data source settings.
axis: It holds the axis name where the draggable field lies.
cancel: It is a boolean property and by setting this to true, user can restrict the field from dragging.

In the below sample, the drag operation for the fields in row axis alone is restricted.

app.vue
<template>
    <div id="app">
        <ejs-pivotview :dataSourceSettings="dataSourceSettings" :height="height" :showGroupingBar="showGroupingBar" :fieldDragStart="fieldDragStart"> </ejs-pivotview>
