Chartjs Tooltip Line Breaks

Question

Is it possible to get line breaks in chartjs tooltips?

tooltipTemplate: \"<%if (label){%><%=label%>: <%}%><%= value %>\"

Answer 1

This worked for me. Just simply return an array of strings as labels in tooltips.

 tooltips: {
    callbacks: {
      label: function(tooltipItem, data) {
        let label = "Line 1";
        let label2 = "Line 2";
        return [label, label2];
      }
    }
  }
