Question

我正在尝试使用Highcharts规格。有没有办法将绘图带设置为线性渐变？如果我的仪表的值为0-100，我希望绘图带从0处的红色变为50处的黄色变为100处的绿色。

我认为我可以为每个停止点生成单独的plotband部分，1-100但是如果有办法设置一个更加清洁的线性隆起。有人知道吗？

Answer 1

是的，有可能。尝试这样的事情：

yAxis: {
        min: 0,
        max: 100,
        plotBands: [{
            color: {
                linearGradient:  [300, 300, 0, 0],
                stops: [
                    [0, 'rgb(255, 255, 255)'],
                    [1, 'rgb(150, 200, 155)']
                ]
            },
            from: 0,
            to: 100
        }],
    },

通过仔细选择颜色，linearGradients和from / to，你应该能够组合几个绘图带来做你想要的。

在

上阅读“LINEAR GRADIENTS”

示例：从黄色到绿色再到红色：

plotBands: [{
    from: 0,
    to: 29,
    color: '#DDDF0D' // yellow
},{
    from: 29,
    to: 40,
    color: {
        linearGradient:  { x1: 0, x2: 0, y1: 0, y2: 1 },
        stops: [
            [0, '#55BF3B'], //green
            [1, '#DDDF0D'] //yellow
        ]
    }
}, {
    from: 40,
    to: 51,
    color: {
        linearGradient:  { x1: 0, x2: 0, y1: 0, y2: 1 },
        stops: [
            [0, '#55BF3B'], //green
            [1, '#DF5353'] //red
        ]
    }
}, {
    from: 51,
    to: 80,
    color: '#DF5353' //red
}]

Highchart的仪表带有梯度绘图带
