@luluprat the method of instantiating charts has changed in v2. You can find documentation at http://nnnick.github.io/Chart.js/docs-v2/

Missing semi colon on var "ctx = this.$.mychart.getContext("2d")" and "console.log(ctx)"

Closing as resolved.

I think you guys should put all two versions documentations on the offical site, and give a hint for that. That would be user-friendly and helpful.
