Cannot bind to class property any more

[Anteru]

This used to work, but seems to broken with Angular 8 and the latest ng2-charts library: When the data is not stored directly in a class field, but a property access is used instead, ng2-charts gets confused and shows much smaller bars than it should. I took the default bar chart sample and replaced:

  public barChartData: ChartDataSets[] = 
      { data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
      { data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
    ];

with

  public get barChartData(): ChartDataSets[] { 
    return [
      { data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
      { data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
    ];
  }
