I'm trying to draw some donut charts with angular.morris-chart.js in my angular app.But when i can't figure out how to add it.  

I added the js file in my libs directory, added it in my index.html after angular call. And i also injected it in my app.  

But it still doesn't work. I get this error in my browser console: 'ReferenceError: Morris is not defined'.  

Any clue to solve my issue ?
