In the Gantt component, timeline is used to represent the project duration as individual cells with defined unit and formats.
Gantt contains the following in-built timeline view modes:
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.
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';
class App extends React.Component<{}, {}>{

};
public timelineSettings: any = {

</GanttComponent>

ReactDOM.render(<App />, document.getElementById('root'));Gantt component contains two tier layout in timeline, we can customize the top tier and bottom tier using topTier and bottomTier properties. Timeline tier’s unit can be defined by using unit property and format property was used to define date format of timeline cell and count property was used to define how many unit will be combined as single cell and formatter property was used to define custom method to format the date value of timeline cell.

ReactDOM.render(<App />, document.getElementById('root'));In the Gantt component, you can format the value of top and bottom timeline cells using the standard date format string or the custom formatter method. This can be done using the topTier.format, topTier.formatter, bottomTier.format and bottomTier.formatter properties. The following example shows how to use the formatter method for timeline cells.

var month = date.getMonth();
if (month >= 0 && month <=2) {
return 'Q1';
} else if(month >= 3 && month <=5) {
return 'Q2';
} else if(month >= 6 && month <=8) {

ReactDOM.render(<App />, document.getElementById('root'));In the Gantt component, you can define the width value of timeline cell using the timelineSettings.timelineUnitSize property. This value will be set to the bottom timeline cell, and the width value of top timeline cell will be calculated automatically based on bottom tier cell width using the topTier.unit and timelineSettings.timelineUnitSize properties. Refer to the following example.

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.

ReactDOM.render(<App />, document.getElementById('root'));The zooming support provides options to increase or decrease the width of timeline cells and also provides options to change the timeline units dynamically. This support enables you to view the tasks in a project clearly from minute to decade timespan. To enable the zooming features, define the ZoomIn, ZoomOut, and ZoomToFit items to toolbar items collections, and this action can be performed on external actions such as button click using the zoomIn, zoomOut, and fitToProject built-in methods. The following zooming options are available to view the project:
This support is used to increase the timeline width and timeline unit from years to minutes
timespan. When the ZoomIn icon was clicked, the timeline cell width is increased when the cell
size exceeds the specified range and the timeline unit is changed based on the current zoom levels.
This support is used to increase the timeline width and timeline unit from minutes to years timespan. When the ZoomOut icon was clicked, the timeline cell width is decreased when the cell size falls behind the specified range and the timeline view mode is changed based on the current zooming levels.
This support is used to view all the tasks available in a project within available area on the chart part of Gantt. When users click the ZoomToFit icon, then all the tasks are rendered within the available chart container width.
