I've got two types of diagrams chart chart-line and chart chart-barand I want to create an html tag like this 

                        <canvas class="category.diagramType"
                            chart-data="category.data"
                            chart-labels="category.labels"
                            chart-legend="true"
                            chart-series="category.series"></canvas>

category is definded in the controller. But setting the class attribute dynamically doesn't work. After Exchanging category.diagramType with chart chart-bar the diagram appreas.

The Question now is: How can i get class="category.diagramType" getting to work?

Just for information: In my real code im using ng-repeat to iterate through a list

angular.module('starter.controllers', [])

    .controller('ProfileCtrl', function ($scope, $http) {
        $scope.categories = [
            {
                title: 'Zeit',
                id: 1,
                labels: ["January", "February", "March", "April", "May", "June", "July"],
                series: ['Series A', 'Series B'],
                data: [[65, 59, 80, 81, 56, 55, 40], [28, 48, 40, 19, 86, 27, 90]],
                diagram: 'chart chart-bar'
            },
            {
                title: 'G-Kräfte', id: 2,

You should use ng-class instead of class so change the code such this

   <canvas ng-class="category.diagramType"
                        chart-data="category.data"
                        chart-labels="category.labels"
                        chart-legend="true"
                        chart-series="category.series"></canvas>

If you just want two classes then you can use ng-class in the following way:

<div ng-class="{'chart chart-bar chart chart-line' : expression}">
    ....
</div>

Where you expression will be something like category.diagramType == 'chart chart-bar'

If you need this for multiple classes then follow the below style:

<div ng-class="{'class1' : expression1, 'class2' : expression2, .....}">
    ....
</div>
