Animation Effect
The animation effect for the RadialSlider can be enabled or disabled using the e-enableanimation property. By default, it is set as true, so that the handle movement will be animated.
<div id="angularRadialSlider" ej-radialslider e-enableanimation="animation" e-innercircleimageurl="http://js.syncfusion.com/demos/web/content/images/radialslider/chevron-right.png"></div>
Add the following script in your code and this will stop the handle movement’s animation.
syncApp.controller('radialSliderCtrl', function ($scope) {
$scope.animation = false;
});
