index.tsx
import * as React from "react";
import * as ReactDOM from "react-dom";
import { AccumulationChartComponent, AccumulationSeriesCollectionDirective, AccumulationSeriesDirective,
 AccumulationTooltip, Inject,TooltipSettingsModel}
from'@syncfusion/ej2-react-charts';
import { accData } from 'datasource.ts';

class App extends React.Component<{}, {}> {

  public tooltip: TooltipSettingsModel = { enable: true };

  render() {
    return <AccumulationChartComponent id='charts' tooltip={this.tooltip}>
      <Inject services={[AccumulationTooltip]} />
      <AccumulationSeriesCollectionDirective>
        <AccumulationSeriesDirective dataSource={accData} xName='x' yName='y'>
        </AccumulationSeriesDirective>
      </AccumulationSeriesCollectionDirective>
    </AccumulationChartComponent>
  }

};
ReactDOM.render(<App />, document.getElementById("charts"));

Note:To use tooltip feature , we need to inject AccumulationTooltip module into the services.

We can specify header for the tooltip using header property.

    </AccumulationChartComponent>
  }

ReactDOM.render(<App />, document.getElementById("charts"));

Format

By default, tooltip shows information of x and y value in points. In addition to that, you can show more information in tooltip. For example the format ${series.name} ${point.x} shows series name and point x value.

Tooltip Mapping Name

By default, tooltip shows information of x and y value in points. You can show more information from datasource in tooltip by using the tooltipMappingName property of the tooltip. You can use the ${point.tooltip} as place holders to display the specified tooltip content.
