How to set hover to specific points in Chart JS?

Question

JavaScript

Preferably, the solution is on version 2.9.4.
I need to change the hover for certain points, in the documentation I found scripted options like:

color: function(context) {
    var index = context.dataIndex;
    var value = context.dataset.data[index];
    return value < 0 ? 'red' :  // draw negative values in red
        index % 2 ? 'blue' :    // else, alternate values in blue and green
        'green';
}

I need the same thing, but for hover
