javascript 在 highcharts 中动态更改点的颜色

Changing the color of the point dynamically in highcharts

提问by Sandeep

I have been able to change the color of point in a graph dynamically, but when I hover over that point then the color of that point is changing to previous color.

我已经能够动态更改图表中点的颜色，但是当我将鼠标悬停在该点上时，该点的颜色会更改为以前的颜色。

I have a fiddle here: jfiddle

我这里有一个小提琴： jfiddle

$(function () {
var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
    }]
});

// the button handler
$('#button').click(function() {

    chart.series[0].data[2].graphic.attr({ fill: '#FF0000' });        
    chart.redraw();
});

How can I change the color of the point dynamically in a graph?
