Time line in React Gantt component

13 Dec 202324 minutes to read

In the Gantt component, timeline is used to represent the project duration as individual cells with defined unit and formats.

Timeline view modes

Gantt contains the following in-built timeline view modes:

  • Hour
  • Day
  • Week
  • Month
  • Year

Timescale mode in Gantt can be defined by using timelineViewMode property and also we can define timescale mode of top tier and bottom tier by using topTier.unit and bottomTier.unit properties.

Week timeline mode

In the Week timeline mode, the upper part of the schedule header displays the weeks, whereas the bottom half of the header displays the days. Refer to the following code example.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent} from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App (){
    const taskFields= {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
 };
  const timelineSettings = {
    timelineViewMode:'Week'
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} height = '450px'>
       </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent} from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App (){
    const taskFields: any = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
 };
  const timelineSettings: any = {
    timelineViewMode:'Week'
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} height = '450px'>
       </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));

Change timeline view mode programmatically

In the Gantt component, the timeline view mode can be modified programmatically. As described below, the Dropdown menu is also used to change the timeline view. The Dropdownlist component can be used to create a dropdown menu. Once the dropdown menu is enabled, the timelineViewMode property from the timelineSettings can be utilized to switch the timeline view between Hour, Day, Week, Month, and Year. Refer to the following code example.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent} from '@syncfusion/ej2-react-gantt';
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';

function App (){
    let ganttInstance;
    const taskFields= {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
 };
 const modes=[
    {
      item: "Hour",
      id:"1"
    },
    {
      item: "Day",
      id:"2"
    },
    {
      item: "Week",
      id:"3"
    },
    {
      item: "Month",
      id:"4"
    },
    {
      item: "Year",
      id:"5"
    }
  ];

  const fields={text:"item", value:"id"};

  function onChange(args) {
    if(args.value==="1")
    {
      ganttInstance.timelineSettings.timelineViewMode="Hour";
    }
    else if(args.value==="2")

Week start day customization

In the Gantt component, you can customize the week start day using the weekStartDay property. By default, the weekStartDay is set to 0, which specifies the Sunday as a start day of the week. But, you can customize the week start day by using the following code example.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
 const timelineSettings = {
    timelineViewMode:'Week',
    weekStartDay: 3
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} height = '450px'>
      </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const taskFields: any = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
 const timelineSettings: any = {
    timelineViewMode:'Week',
    weekStartDay: 3
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} height = '450px'>
      </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));

Customize automatic timescale update action

In the Gantt component, the schedule timeline will be automatically updated when the tasks date values are updated beyond the project start date and end date ranges. This can be enabled or disabled using the updateTimescaleView property.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Edit, Selection } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const editOptions = {
    allowEditing: true,
    allowTaskbarEditing: true
  };
  const timelineSettings = {
    updateTimescaleView: false
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} allowSelection={true}
        editSettings={editOptions} height = '450px'>
            <Inject services={[Edit, Selection]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Edit, EditSettingsModel, Selection } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const taskFields: any = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const editOptions: EditSettingsModel = {
    allowEditing: true,
    allowTaskbarEditing: true
  };
  const timelineSettings: any = {
    updateTimescaleView: false
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        timelineSettings={timelineSettings} allowSelection={true}
        editSettings={editOptions} height = '450px'>
            <Inject services={[Edit, Selection]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));

Timeline cells tooltip

In the Gantt component, you can enable or disable the mouse hover tooltip of timeline cells using the timelineSettings.showTooltip property. The default value of this property is true. The following code example shows how to enable the timeline cells tooltip in Gantt.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const  taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const  timelineSettings = {
    showTooltip: true
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
            timelineSettings={timelineSettings} height = '450px'>
      </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
   const  taskFields: any = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const  timelineSettings: any = {
    showTooltip: true
  };
        return <GanttComponent dataSource={data} taskFields={taskFields}
            timelineSettings={timelineSettings} height = '450px'>
      </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
