You need to use <ng-template matTabContent>
It wiil look something like that:
<mat-tab label="example">
<ng-template matTabContent>
<div class="chart-area">
<canvas baseChart
[chartType]="'bar'"
[datasets]="[chartConfig.chartData]"
[labels]="chartConfig.chartHours"
[options]="chartConfig.chartOptions"
[colors]="[chartConfig.chartColors]">
</canvas>
</div>
</ng-template>
</mat-tab>
