Current behavior Trying to set the label property of a pie-grid throws an exception.

Expected behavior It should change the text shown in front of the total value, under the pie grid chart.

Reproduction of the problem https://plnkr.co/edit/7zS2fUVEFE2L9v7HBLrl?p=preview See the console log:

Error: Uncaught (in promise): Error: Template parse errors:
Can't bind to 'label' since it isn't a known property of 'ngx-charts-pie-grid'.
1. If 'ngx-charts-pie-grid' is an Angular component and it has 'label' input, then verify that it is part of this module.
2. If 'ngx-charts-pie-grid' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("
    <ngx-charts-pie-grid
      [view]="view"
      [scheme]="colorScheme" [ERROR ->][label]="'Total People'"
      [results]="single" [designatedTotal]="89400000"
      (select)="onSele"): ng:///AppModule/App.html@3:29

What is the motivation / use case for changing the behavior? The docs say:

Property	Type	Default Value	Description
label	string	‘Total’	the text to show under the total value
