The other possibility is using angular display system.
If you use %angular instead of %html, you'll able to send some data to
front-end side by doing
val x1=Vector(0,1,2,3,4)
z.angularBind("x1", x1.toArray)
println("%angular x1={{x1}}")
You can also access this variable in JS, by printing javascript like
%angular
<script>
var controllerElement = document.querySelector('[ng-app=zeppelinWebApp]');
var scope = angular.element(controllerElement).scope().compiledScope;
console.log("x1=%o", scope.x1)
<script>
Hope this helps.
Thanks,
