  View All Statuses
</mat-slide-toggle>

<div class="row">
    <div class="col-12 d-block">

      <svg id="stacked-bar-chart" width="550" height="300"></svg>
    </div>

Answer 1

try this it will works, otherwise you can use [ngClass]="bool ? 'd-block' : 'd-none'"

 $("#toggleclick").click(function () { if($(".d-block").hasClass("hide")) { $(".d-block").removeClass("hide"); $(".d-none").addClass("hide"); } else if($(".d-none").hasClass("hide")) { $(".d-none").removeClass("hide"); $(".d-block").addClass("hide"); } }) 

 .d-block{ background:#ff0; } .d-none{ background:#0ff; } .hide{ display:none; } mat-slide-toggle{ cursor:pointer; }

Below code using Angular's ngClass directive

HTML:

<mat-slide-toggle [(ngModel)]="checked">
  View All Statuses
</mat-slide-toggle>

<div class="row">
    <div class="col-12" [ngClass]="checked ? 'd-none' : 'd-block'">
      <svg id="bar-chart" width="550" height="300"></svg>Hello
    </div>
    <div class="col-12" [ngClass]="checked ? 'd-none' : 'd-block'">
      <svg id="stacked-bar-chart" width="550" height="300"></svg>World
    </div>
</div>

CSS:

.d-block {
    display: block;
}

.d-none {
    display: none;
}
