|-- @syncfusion/ej2-react-baseSetup for Local Development
You can use create-react-app to setup the application. To install create-react-app run the following command.
```
npm install -g create-react-app
```
To create basic React application use following commands.
<div class='tsx'>
```
create-react-app quickstart --scripts-version=react-scripts-ts
```
Now, the application is created in the quickstart demo folder. Run the following command one-by-one to navigate to the quickstart demo folder, and install the required npm dependent packages.
```
cd quickstart
npm install
```
</div>
<div class='jsx'>
```
create-react-app quickstart
```
Now, the application is cloned in the quickstart demo folder. Run the following command one-by-one to navigate to the quickstart demo folder, and install the required npm dependent packages.
```
cd quickstart
npm install
```
</div>
Adding Syncfusion packages
All the available Essential JS 2 packages are published in npmjs.com public registry. To install pivot table component, use the following command.
```
npm install @syncfusion/ej2-react-pivotview --save
```
The –save will instruct NPM to include the pivot table package inside the
dependenciessection of thepackage.json.
Adding CSS reference
Add pivot table and its dependent components styles as given below in src/App.css file. In this illustration, we have referred material theme.
```css
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import '../node_modules/@syncfusion/ej2-grids/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-react-pivotview/styles/material.css';
```
You can also refer other themes like bootstrap, fabric, high-contrast etc. To know about individual component CSS, please refer here.
Next we need to refer App.css in the application by importing it in the src/App.tsx file as follows.
import './App.css';Adding pivot table component
You can initialize pivot table component in the application using following steps.
- Import the PivotViewComponent (aka, PivotTable) component from the @syncfusion/ej2-react-pivotview package in app.ts file.
-
Then you can initialize pivot table component (
<PivotViewComponent/>) using following code.import { IDataOptions, PivotViewComponent } from '@syncfusion/ej2-react-pivotview'; import * as React from 'react'; import './App.css'; function App() { return <PivotViewComponent/> }; export default App;
After initialization, add the the following code in src/App.tsx file to populate pivot table with a sample OLAP data source. Refer here to know the more details about OLAP data binding.
```ts
import { IDataOptions, PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
import * as React from 'react';
import './App.css';
function App() {
let dataSourceSettings: IDataOptions = {
catalog: 'Adventure Works DW 2008 SE',
cube: 'Adventure Works',
enableSorting: true,
localeIdentifier: 1033,
providerType: 'SSAS',
url: 'https://bi.syncfusion.com/olap/msmdpump.dll',
}
let pivotObj: PivotViewComponent;
return (<PivotViewComponent ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings} />)
};
export default App;
ReactDOM.render(<App />, document.getElementById('sample'));
```
```ts
import { PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
import * as React from 'react';
import './App.css';
function App() {
let dataSourceSettings = {
catalog: 'Adventure Works DW 2008 SE',
cube: 'Adventure Works',
enableSorting: true,
localeIdentifier: 1033,
providerType: 'SSAS',
url: 'https://bi.syncfusion.com/olap/msmdpump.dll',
};
let pivotObj;
return (<PivotViewComponent ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings}/>);
}
;
export default App;
ReactDOM.render(<App />, document.getElementById('sample'));
```
Adding OLAP cube elements to row, column, value and filter axes
Now that pivot table is initialized and assigned with sample OLAP data source, will further move to showcase the component by organizing appropriate OLAP cube elements in rows, columns, values and filters axes.
In dataSourceSettings property, four major axes rows, columns, values and filters plays a vital role in defining and organizing OLAP cube elements from the bound data source, to render the entire pivot table component in a desired format.
rows – Collection of OLAP cube elements (such as Hierarchies, NamedSet, Calculated Members etc.,) that needs to be displayed in row axis of the pivot table.
columns – Collection of OLAP cube elements (such as Hierarchies, NamedSet, Calculated Members etc.,) that needs to be displayed in column axis of the pivot table.
values – Collection of OLAP cube elements (such as Measures, Calculated Measures) that needs to be displayed as aggregated numeric values in the pivot table.
filters - Collection of OLAP cube elements (such as Hierarchies and Calculated Members) that would act as master filter over the data bound in row, column and value axes of the pivot table.
In-order to define each OLAP cube element in the respective axis, the following basic properties should be set.
-
name: It allows to set the unique name of the hierarchies, named set, measures, calculated members etc., from the bound OLAP data source. It’s casing should match exactly like in the data source and if not set properly, the pivot table will be rendered as empty. -
caption: It allows to set the caption, which is the alias name of the unique name that needs to be displayed in the pivot table. If not provided, unique name will be displayed.
In this sample, “Product Categories” is added in column, “Customer Geography” in row, and “Customer Count” and “Internet Sales Amount” in value axes respectively.
import * as React from 'react';
import { PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
function App() {
let dataSourceSettings = {
catalog: 'Adventure Works DW 2008 SE',
cube: 'Adventure Works',
providerType: 'SSAS',
enableSorting: true,
url: 'https://bi.syncfusion.com/olap/msmdpump.dll',
localeIdentifier: 1033,
rows: [
{ name: '[Customer].[Customer Geography]', caption: 'Customer Geography' },
],
columns: [
{ name: '[Product].[Product Categories]', caption: 'Product Categories' },
{ name: '[Measures]', caption: 'Measures' },
],
values: [
{ name: '[Measures].[Customer Count]', caption: 'Customer Count' },
{ name: '[Measures].[Internet Sales Amount]', caption: 'Internet Sales Amount' }
]
};
let pivotObj;
return (<PivotViewComponent ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings}>
</PivotViewComponent>);
};
export default App;import * as React from 'react';
import { IDataOptions, IDataSet, PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
function App() {
let dataSourceSettings: IDataOptions = {
catalog: 'Adventure Works DW 2008 SE',

{ name: '[Product].[Product Categories]', caption: 'Product Categories' },
{ name: '[Measures]', caption: 'Measures' },
],
values: [
{ name: '[Measures].[Customer Count]', caption: 'Customer Count' },
{ name: '[Measures].[Internet Sales Amount]', caption: 'Internet Sales Amount' }
]
};
let pivotObj: PivotViewComponent;
return (<PivotViewComponent ref={ (d: PivotViewComponent) => pivotObj = d } id='PivotView' height={350} dataSourceSettings={dataSourceSettings}>
</PivotViewComponent>);
};
export default App;Applying formatting to measures
Formatting defines a way in which values should be displayed in pivot table. For example, format “C0” denotes the values should be displayed in currency pattern without decimal points. To do so, define the formatSettings with its name and format properties. In this sample, the name property is set as “[Measures].[Internet Sales Amount]”, a measure from value axis and its format is set as “C0”. Likewise, we can set format for other measures as well.
Only measures from value axis, which is in the form of numeric data values are applicable for formatting.
import * as React from 'react';
import { PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
function App() {
let dataSourceSettings = {
catalog: 'Adventure Works DW 2008 SE',
cube: 'Adventure Works',

],
values: [
{ name: '[Measures].[Customer Count]', caption: 'Customer Count' },
{ name: '[Measures].[Internet Sales Amount]', caption: 'Internet Sales Amount' }
],
formatSettings: [{ name: '[Measures].[Internet Sales Amount]', format: 'C0' }]
};
let pivotObj;
return <PivotViewComponent ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings}>
</PivotViewComponent>;
};
export default App;import * as React from 'react';
import { IDataOptions, IDataSet, PivotViewComponent } from '@syncfusion/ej2-react-pivotview';

};
let pivotObj: PivotViewComponent;
return <PivotViewComponent ref={ (d: PivotViewComponent) => pivotObj = d } id='PivotView' height={350} dataSourceSettings={dataSourceSettings}>
</PivotViewComponent>
};
export default App;Enable grouping bar
The Grouping Bar feature automatically populates OLAP cube elements from the bound data source and allows end users to drag OLAP cube elements between different axes such as rows, columns, values and filters, and change pivot view at runtime. Sorting, filtering and removing of elements is also possible. It can be enabled by setting the showGroupingBar property to true and by injecting the GroupingBar module as follows.
If the GroupingBar module is not injected, the grouping bar will not be rendered with the pivot table component.
import * as React from 'react';
import { Inject, PivotViewComponent, GroupingBar } from '@syncfusion/ej2-react-pivotview';

};
export default App;Enable pivot field list
The component provides a built-in Field List similar to Microsoft Excel. It allows you to add or remove OLAP cube elements and also rearrange the OLAP cube elements between different axes, including rows, columns, values and filters along with filter and sort options dynamically at runtime. It can be enabled by setting the showFieldList property to true and by injecting the FieldList module as follows.
If the FieldList module is not injected, the Field List will not be rendered with the pivot table component.

};
export default App;Exploring filter axis
The filter axis contains collection of OLAP cube elements such as hierarchies and calculated members that would act as master filter over the data bound in rows, columns and values axes of the pivot table. The OLAP cube elements along with filter members could be set to filter axis either through report via code behind or by dragging and dropping OLAP cube elements from other axes to filter axis via grouping bar or field list at runtime.

export default App;Calculated field
The calculated field allows user to insert or add a new calculated field based on the available OLAP cube elements from the bound data source. Calculated fields are nothing but customized dimensions or measures that are newly created based on the user-defined expression.
The two types of calculated fields are as follows:
- Calculated Measure – Creates a new measure through user-defined expression.
- Calculated Dimension – Creates a new dimension through user-defined expression.
It can be customized using the calculatedFieldsSettings property through code behind. The setting required for calculate field feature at code behind are:
-
name: It allows to set the unique name for new calculated field. -
formula: It allows to set the user-defined expression. -
hierarchyUniqueName: It allows to specify dimension unique name whose hierarchies alone should be used in the expression. This will be applicable only for calculated dimension. -
formatString: It allows to set the format string for the resultant calculated field.
You need to set isCalculatedField property to true, while adding calculated fields to respective axis through code behind.
Also calculated fields can be added at run time through the built-in dialog. The dialog can be enabled by setting the allowCalculatedField property to true and by injecting the CalculatedField module as follows. You will see a button enabled in the Field List UI automatically to invoke the calculated field dialog and perform necessary operation.
If the CalculatedField module is not injected, the calculated field dialog will not be rendered with the pivot table component. Moreover calculated measure can be added only in value axis.

};
export default App;Users can add a calculated field at runtime through the built-in dialog by using the following steps.
Step 1: Click the “CALCULATED FIELD” button in the field list dialog positioned at the top right corner. The calculated field dialog will be opened now. Enter the name of the calculated field to be created.
Step 2: Frame the expression by dragging and dropping the fields from the tree view on the left side of the dialog using simple arithmetic operators. Example: “IIF([Measures].[Internet Sales Amount]^0.5 > 100, [Measures].[Internet Sales Amount]*100, [Measures].[Internet Sales Amount]/100)”. Please refer here to learn more about the supported operators and functions to frame the expression.
Step 3: Confirm the type of the field to be created - calculated measure or calculated dimension.
Step 4: Choose the parent hierarchy of the calculated field. NOTE: It is only applicable to the calculated dimension.
Step 5: Then select the format string from the drop-down list and finally click “OK”.
Format String
Allows you to specify the required format string while creating new calculated field. Supported format strings are:
- Standard - Denotes the numeric type.
- Currency - Denotes the currency type.
- Percent - Denotes the percentage type.
- Custom - Denotes the custom format. For example: “###0.##0#”. This shows the value “9584.3” as “9584.300.”
By default, Standard will be selected from the drop down list.
Renaming the existing calculated field
Existing calculated field can be renamed only through the UI at runtime. To do so, open the calculated field dialog, click the target field. User can now see the existing name getting displayed in the text box at the top of the dialog. Now, change the name based on user requirement and click “OK”.
Editing the existing calculated field formula
Existing calculated field formula can be edited only through the UI at runtime. To do so, open the calculated field dialog, click the target field. User can now see the existing expression getting displayed in a “Expression” section. Now, change the expression based on user requirement and click “OK”.
Reusing the existing formula in a new calculate field
While creating a new calculated field, if user wants to the add the formula of an existing calculated field, it can be done easily. To do so, simply drag-and-drop the existing calculated field to the “Expression” section.
Modifying the existing format string
Existing calculated field’s format string can be modified only through the UI at runtime. To do so, open the calculated field dialog and click the target calculated field. User can now see the format string for the existing calculated field getting displayed in a drop-down list. Change the format string based on the requirement and finally click “OK”.
Clearing the changes while editing the calculated field
Previous changes can be cleared by using the “Clear” option while performing operations such as creating and editing the calculated field. To do so, click the “Clear” button in the bottom left corner of the dialog.
Virtual Scrolling
Allows large amounts of data to be loaded without any performance degradation by rendering rows and columns in relation to the current viewport. Rest of the data will be brought into the viewport dynamically based on vertical or horizontal scroll position. This feature can be enabled by setting the enableVirtualization property to true.
To use the virtual scrolling feature, inject the VirtualScroll module into the pivot table.

export default App;Limitations for virtual scrolling
- In virtual scrolling, the columnWidth property in gridSettings should be in pixels, and percentage values are not accepted.
- Resizing columns or setting width to individual columns affects the calculation used to pick the correct page on scrolling.
- When using OLAP data, subtotals and grand totals are only displayed when measures are bound at the last position in the rows or `columns axis. Otherwise, the data from the pivot table will be shown without summary totals.
- When the pivot table’s width and height are large, the loading data count in the current, previous, and next viewports (pages) will also increase, affecting performance.

Field list
The field list, aka cube dimension browser, is a tree view like structure that organizes the cube elements such as dimensions, hierarchies, measures, etc., from the selected cube into independent logical groups.
Types of node in field list
- Display folder: A folder that contains a set of similar elements.
- Measure: Quantity available for analysis.
- Dimension: A name given to the parts of the cube that categorizes data.
- Attribute Hierarchy: Level of attributes down the hierarchy.
- User-defined Hierarchy: Members of a dimension in a hierarchical structure.
- Level: Denotes a specific level in the category.
- Named Set: A collection of tuples and members, that can be defined and saved as a part of cube definition for later use.
Measure
In a cube, a measure is a set of values that are based on a column in the cube’s fact table and are usually numeric. The measures are the central values of a cube that are analyzed. That is, measures are the numeric data of primary interest to users browsing a cube. You can select measures depend on the types of users request. Some common measures are sales, costs, expenditures, and production count.
Dimension
A simple dimension object is composed of basic information such as name, hierarchy, level, and members. You can create a dimension element by specifying its name and providing the hierarchy and level name. The dimension element contains the hierarchical details and information about each included level elements in that hierarchy. A hierarchy can have any number of level elements and the level elements can have any number of members and the member elements can have any number of child members.
Hierarchy
Each element of a dimension can be summarized using a hierarchy. The hierarchy is a series of parent-child relationship, where a parent member represents the consolidation of members which are its children. Parent members can be further aggregated as the children of another parent. For example, May 2005 can be summarized into Second Quarter 2005 which in turn would be summarized in the year 2005.
Level
Level element is the child of hierarchy element which contains a set of members, each of which has the same rank within a hierarchy.
Attribute hierarchy
Attribute hierarchy contains the following levels:
- A leaf level contains distinct attribute member, and each member of the leaf level is known as a leaf member.
- Intermediate levels if the attribute hierarchy is a parent-child hierarchy.
- An optional (all) level contains the aggregated value of the attribute hierarchy’s leaf members, with the member of the (all) level also known as the (all) member.
User-defined hierarchy
User-defined hierarchy organizes the members of a dimension into hierarchical structure and provides navigation paths in a cube. For example, take a dimension table that supports three attributes such as year, quarter, and month. The year, quarter, and month attributes are used to construct a user-defined hierarchy, named Calendar, in the time dimension that relates to all levels.
Differentiating user-defined hierarchy and attribute hierarchy
- User-defined hierarchy contains more than one level whereas attribute hierarchy contains only one level.
- User-defined hierarchy provides the navigation path between the levels taken from attribute hierarchies of the same dimension.
- The attribute hierarchy and the user-defined hierarchy are represented in different ways as shown in the following table.
Named set
A named set is a collection of tuples and members, which can be defined and saved as a part of the cube definition. Named set records reside inside the sets folder, which is under a dimension element. These elements can be dragged to rows or columns axis via grouping bar or field list at runtime. To work with a lengthy, complex, or commonly used expression easier, Multidimensional Expressions (MDX) allows you to define a named set.
Calculated field
The calculated field allows user to insert or add a new calculated field based on the available OLAP cube elements from the bound data source. Calculated fields are nothing but customized dimensions or measures that are newly created based on the user-defined expression.
The two types of calculated fields are as follows:
- Calculated Measure – Creates a new measure through user-defined expression.
- Calculated Dimension – Creates a new dimension through user-defined expression.
