startAngle not working on PolarChart #4093

Description

@hankolehel

So I decided to use the PolarChart for my data visualizing project and wanted to rotate the chart to the left by 45 degrees.
After a lot of time researched on the internet I have concluded that this should work perfectly fine


<div>
  <div style="display: block">
    <canvas baseChart
            [data]="polarAreaChartData"
            [labels]="polarAreaChartLabels"
            [legend]="polarAreaLegend"
            [options]="polarChartOptions"
            [chartType]="polarAreaChartType"
            (chartHover)="chartHovered($event)"
            (chartClick)="chartClicked($event)"></canvas>
  </div>
  <button (click)="randomize()">Update</button>
</div>

This is my Angular2 file, declaring polarChartOptions, where I would follow up on further customizing it.

import { Component, OnInit } from '@angular/core';
import { PostsService } from '../posts.service';

@Component({
  selector: 'app-posts',
  templateUrl: './posts.component.html',
  styleUrls: ['./posts.component.css']
})
export class PostsComponent implements OnInit {

 // PolarArea
  public polarAreaChartLabels:string[] = ['A','B','C','D','E','F','G','H', 'I'];
  public polarAreaChartData:number[] = [100, 80, 110, 20, 20, 20, 20, 20, 20];
  public polarAreaLegend:boolean = true;

  public polarAreaChartType:string = 'polarArea';

  public polarChartOptions:any = {
      startAngle: 90,
      legend: false
    };

  // events
  public chartClicked(e:any):void {
    console.log(e);
  }

  public chartHovered(e:any):void {
    console.log(e);
  }


  constructor(private postsService: PostsService) { }

  }
}

Any help would be greatly appreciated.
