Hide/disable tooltips chart.js

I'm trying to hide the tooltips in a line chart using chart.js.

I have tried this code, but they never hide.

Chart.defaults.global.tooltipenabled = false;

You can see all the code here of the chart:

To turn off for a specific chart instead of in global defaults use this in the options object. Using v2.5.0

options: {
    tooltips: {
         enabled: false
    }
}
