Using tooltipRender event, you can able to format the
datetime value instead of rendered value.
To format the datetime value,please follow the steps below
Step 1:
By using tooltipRender event we can able to get
the current point x value. Using this value to format the tooltip by using formatDate method.
The output will appear as follows,
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,
Legend, DateTime, Tooltip, DataLabel, LineSeries, ITextRenderEventArgs, ITooltipRenderEventArgs,AxisModel,TooltipSettingsModel }
from'@syncfusion/ej2-react-charts';
import { Internationalization } from '@syncfusion/ej2-base';
class App extends React.Component<{}, {}> {
public data: any[] = [
{ x: new Date(2005, 0, 1), y: 21 }, { x: new Date(2006, 0, 1), y: 24 },
{ x: new Date(2007, 0, 1), y: 30 }, { x: new Date(2008, 0, 1), y: 38 },
{ x: new Date(2009, 0, 1), y: 54 }, { x: new Date(2010, 0, 1), y: 57 },
];
public primaryxAxis: AxisModel = { valueType: 'DateTime' };
public marker = { visible: true, height: 10, width: 10, dataLabel: { visible: true } };
public tooltip: TooltipSettingsModel = { enable: true };
public tooltipRender = (args: ITooltipRenderEventArgs) => {
let intl: Internationalization = new Internationalization();
let formattedString: string = intl.formatDate(new Date(args.point.x), { skeleton: 'yMd' });
args.text = formattedString;
};
render() {
