Gapi analytics ext undefined (js)
I am trying to use google analytics api (javascript) to display some charts (combined with charts.js).
I followed the instructions here: tuto gapi
I created an application and I replaced my clientId in the code, but I have an error:
gapi.analytics.ext undefined
Here is my code:

Does anyone know how to customize my application? Did I do something wrong?
Thanks for the help!
