有什么方法可以根据节点颜色禁用在 highcharts 网络图中的某些节点上的悬停动作。？

Question

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

We implemented search for nodes of network graph and made the nodes which are not matched to gray color. Now we need to disable the hover effect to the nodes which are in gray color. Any Inputs are Welcome

Answer 1

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));
