Legend in Angular Treemap component

23 Sep 202324 minutes to read

Legend is used to provide valuable information for interpreting what the TreeMap displays. The legends can be represented in various colors, shapes or other identifiers based on the data.

Position and alignment

Legend position is used to place legend in various positions. Based on the legend position, the legend item will be aligned. For example, if the position is top or bottom, the legend items are placed by rows. If the position is left or right, the legend items are placed by columns.

The following options are available to customize the legend position:

  • Top
  • Bottom
  • Left
  • Right
  • Float

Legend Alignment is used to align the legend items in specific location. The following options are available to customize the legend alignment:

  • Near
  • Center

Legend mode

The TreeMap control supports two different types of legend rendering modes such as Default and Interactive.

Default mode

In default mode, the legends have symbols with legend labels that are used to identify the items in the TreeMap.

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

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;'  [dataSource]='data' weightValuePath='count' [legendSettings]='legendSettings'
    [leafItemSettings]='leafItemSettings' equalColorValuePath='Brand'>
    </ejs-treemap>`
})
export class AppComponent {
    public data: object[] = [{ Car:'Mustang', Brand:'Ford', count:232 },
                       { Car:'EcoSport', Brand:'Ford', count:121 },
                       { Car:'Swift', Brand:'Maruti', count:143 },
                       { Car:'Baleno', Brand:'Maruti', count:454 },
                       { Car:'Vitara Brezza', Brand:'Maruti', count:545 },
                       { Car:'A3 Cabriolet', Brand:'Audi',count:123 },
                       { car:'RS7 Sportback', Brand:'Audi', count:523 }

               color:'green'
           },
           {

platformBrowserDynamic().bootstrapModule(AppModule);

Interactive mode

The legends can be made interactive with an arrow mark that indicates exact range color in the legend when the mouse hovers on the TreeMap item. Enable this option by setting the mode property in the legendSettings to Interactive.

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

@Component({
    selector: 'app-container',

Legend size

Customize the legend size by modifying the height and width properties in the legendSettings. It accepts values in both percentage and pixel.

Bind legend item text from data source

To show the legend item text from the data source, bind the property name from data source to the valuePath property in the legendSettings.

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

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;'  [dataSource]='data' weightValuePath='count' [legendSettings]='legendSettings'
    [leafItemSettings]='leafItemSettings' colorValuePath ='color'>
    </ejs-treemap>`
})

Hide duplicate legend items

To enable or disable the duplicate legend items, set the removeDuplicateLegend property to true in the legendSettings.

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

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;'  [dataSource]='data' weightValuePath='count' [legendSettings]='legendSettings'

Legend Responsiveness

Use a responsive legend that switches positions between the right and the bottom based on the available height and width. To enable the responsive legend, set the position property to Auto in the legendSettings and the legend position is changed based on the available height and width.

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

    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;' [palette] ='palette' [dataSource]='data' weightValuePath='count'

                       { fruit:'Orange', count:2300 },
