Sets the color of line connecting index labels with their dataPoint. It is only applicable for pie and doughnut chart when indexLabelPlacement is outside. For other chart-types, indexLabelLineThickness should be set greater than zero. The value of indexLineColor can be a “HTML Color Name” or “hex code” or “rgba values” .
var chart = new CanvasJS.Chart("container",
{
.
.
data: [{
dataPoints: [
{ y: 10, indexLabel:"apple", indexLabelLineColor: "green" },
],
},
]
.
.
});
chart.render();

Is it possible to remove labels and their lines in the graph, but still keep it in the tooltip?
Yes, you can hide labels by setting valueFormatString of axis to a space character and hide ticks by setting tickLength to 0. Please refer to this example.
