Chartjs-Click every label onload ChartJS

This works for me:

 multiLineChart.legend.legendItems[0].hidden = true;
 multiLineChart.data.datasets[0].hidden = true;

For some reason the update method didn’t quite work, but this did:

function init() {
 myBarChart = new Chart(ctx, {
  type: chartType,
  data: data,
  options: options
 });
myBarChart.legend.legendItems[0].hidden = true;
myBarChart.data.datasets[0].hidden = true;
}

And your function:

multiLineChart.legend.legendItems.forEach(function(label, key) {
  multiLineChart.legend.legendItems[key].hidden = true;
  multiLineChart.data.datasets[key].hidden = true;
});

Result:
