[Solved]-Is there any way to disable hover action on particularly some nodes in networkchart of highcharts based on the node color.?-Highcharts

you can add the below small plugin to prevent all hover effects on a point depending on a color.

(function(h) {
    h.wrap(h.point.prototype, 'onmouseover', function(proceed) {
        if (this.color !== 'red') {
            proceed.apply(this, array.prototype.slice.call(arguments, 1));
        }
    });
}(highcharts));
