Chart.js v2 hide dataset labels

Just set the label and tooltip options like so

...
options: {
    legend: {
        display: false
    },
    tooltips: {
        callbacks: {
           label: function(tooltipItem) {
                  return tooltipItem.yLabel;
           }
        }
    }
}

Fiddle - http://jsfiddle.net/g19220r6/

add:

Chart.defaults.global.legend.display = false;

in the starting of your script code;

As of 2021, the namespace has changed from options.legend to options.plugins.legend. This simple code worked for me -

data{
...
},
options: {
  plugins: {
    legend: {
      display: false
    }
  }
}
