Tooltip in Angular 3D Chart control

12 Jan 202421 minutes to read

The 3D Chart will display details about the points through tooltip, when the mouse is moved over the specific point.

By default, tooltip is not visible. The tooltip can be enabled by setting the enable property in tooltipSettings to true and by injecting Tooltip3DService module into the @NgModule.providers.

import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    // specifies the template string for the Chart component
    template: `<ejs-chart3d style='display:block;' align='center' [primaryXAxis]='primaryXAxis' [tooltip]="tooltip"

})
export class AppComponent {

            labelPlacement: 'BetweenTicks'
        };
        this.enableRotation = true;

By default, tooltip track the mouse movement, but the tooltip can be set in fixed position by using the location property.

By default, tooltip shows information of x and y value in points. In addition to that, more information can be shown in tooltip by using the format property. For example the format ${series.name} : ${point.y} shows series name and point y value.

Any HTML elements can be displayed in the tooltip by using the template property of the tooltip. The ${x} and ${y} can be used as place holders in the HTML element to display the x and y values of the corresponding data point.

The fill and border properties are used to customize the background color and border of the tooltip respectively. The textStyle property in the tooltip is used to customize the font of the tooltip text.
