Histogram Chart Buckets

Following is an example of a Histogram Chart with custom bucket size.

We have already seen the configurations used to draw a chart in Google Charts Configuration Syntax chapter. Now, let us see an example of a histogram chart with custom bucket size.

Configurations

We've used bucketSize configuration to change default bucket size of histogram chart.

options = {   
   legend:'none',
   colors:['green'],
   histogram: { bucketSize: 5 }
};

Example

app.component.ts

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'Students height, in cm';
   type = 'Histogram';
   data = [
      ["1", 80],["2", 55],["3", 68],["4", 80],["5", 54],
      ["6", 70],["7", 85],["8", 78],["9", 70],["10", 58],
      ["11", 90],["12", 65],["13", 88],["14", 82],["15", 65],
      ["16", 86],["17", 45],["18", 62],["19", 84],["20", 75],
      ["21", 82],["22", 75],["23", 58],["24", 70],["25", 85]
   ];
   columnNames = ["Student Roll No", "height"];
   options = {   
      legend:'none',
      colors:['green'],
      histogram: { bucketSize: 5 }
   };
   width = 550;
   height = 400;
}
