[Solved] Getting TypeError: undefined is not a function in scatterplot

[Casper]

I've setup a scatterplot as in the documentation and I'm getting the above error when hovering in the chart area after having clicked one of the graph points.

Controller contains this:
​$scope.onSeriesHover = function (e) {
}

function getDataForGraph() {
    graphDataService.getData('issuer.sector', $scope.selectedSector).then(function (result) {
        $scope.data = result;
});
}
and the view this:
<div kendo-chart
k-series-defaults="{type: 'scatter'}"
k-series="[{xField:'duration', yField:'cost'}]"
k-x-axis="{
labels: { format: '{0}' },
title: { text: 'Duration' }
}"
k-y-axis="{
labels: { format: '{0}' },
title: { text: 'Cost }
}"
k-data-source="data"
k-series-click="onSeriesClick"
k-series-hover="onSeriesHover"></div>

After the controller is initialized the getDataForGraph method is called.
It displays data perfectly but I get this TypeError all the time after the first click on the graph.

I've attached a screenshot from the chrome dev tools if this could help. As I'm on the trial version I do not have access to the full code.

It appears doing the below stops this error:

​$scope.onSeriesHover = function (e) {
    e.preventDefault();
}

but this should hardly be necessary?

It also happens on the demo site, see attached.

Hi Casper,
 
This is a known issue, however it has been already addressed - the fix is available in our latest internal build. I would suggest to open a support ticket where we will send you one (as we cannot send internal builds in public forums).
