Chartjs-Legends in Chart.js, shows only one label

It seems that charts.js labels only works when you split the datasets.

Leaving an example.
https://jsfiddle.net/code4mk/1j62ey38/

datasets: [ {
          label: 'Result',
          fill:false,
          data: aDatasets1,
          backgroundColor: '#E91E63',
          },
         {
          label: 'Result2',
          fill:false,
          data: aDatasets2,
          backgroundColor: '#E91E93',
    }];
