Legend in Angular Accumulation chart component
27 Sep 202324 minutes to read
As like a chart, the legend is also available for accumulation charts, which gives information about the points.
By default, the legend will be placed on the right, if the width of the chart is high or will be placed on the bottom, if the height of the chart is high. Other customization features regarding the legend element are same as the chart legend
.
Here, the legend for a point can be collapsed by giving the empty string to the x value of the point.
import { Component, OnInit } from '@angular/core';
import { pieData } from './datasource';
@Component({

Position and Alignment
By using the position property, you can position the legend at the left
, right
, top
or bottom
of the chart.
You can also align the legend to center
, far
or near
of the chart using the alignment property.
import { Component, OnInit } from '@angular/core';
import { pieData } from './datasource';
@Component({

Legend Reverse
You can reverse the order of the legend items by using the reverse
property. By default, legend for the first series in the collection will be placed first.
import { Component, OnInit } from '@angular/core';
import { pieData } from './datasource';
@Component({

Legend Shape
To change the legend icon shape, use the legendShape
property in the series
. By default, legend icon shape is seriesType
.
import { Component, OnInit } from '@angular/core';
import { pieData } from './datasource';
@Component({

Legend Text Wrap
When the legend text exceeds the container, the text can be wrapped by using textWrap
Property. End user can also wrap the legend text based on the maximumLabelWidth
property.

Legend Title
You can set title for legend using title
property in legendSettings
. You can also customize the fontStyle
, size
, fontWeight
, color
, textAlignment
, fontFamily
, opacity
and textOverflow

is used to set the legend position in Top
, Left
and Right
position. maximumTitleWidth
is used to set the width of the legend title. By default, it will be 100px
.

Arrow Page Navigation
By default, the page number will be enabled while legend paging. Now, you can disable that page number and also you can get left and right arrows for page navigation. You have to set false
value to enablePages
to get this support.
