✅

That for-loop never gets beyond the first iteration because the body contains a return. To return an array resulting from all iterations, create an array variable, push to it in the loop, then return that array…

        datasets: function() {
          let labelObjects = [];
          let dataset = courbeSatisfactionserv.dataset; // easier on the eyes
          for (let i = 0; i < (dataset.size); i++) {
            let labelObject = {
              datalabels: {
                display: false,
              },
              label: JSON.parse(dataset[`points_lab_${i}`]),
              data: JSON.parse(dataset[`points_${i}`]),
              fill: false,
              borderColor: '#442B48',
              backgroundColor: '#442B48',
              borderWidth: 2
            }
            labelObjects.push(labelObject);
          }
          return labelObjects;
        }
