数据可视化大屏项目中,为了当大屏元素多样化,3d饼状图也是不可缺少的元素,今天整理的是根据数据显示不同高低的饼状图效果。 可能遇到窗口大小变化后会出现错位情况: highcharts不同高低的3d饼状图窗口变化后错位问题

首先引入highcharts

这里使用的是10.1.0版本的highcharts

<script src="//cdn.staticfile.org/highcharts/10.1.0/highcharts.js"></script>
<script src="//cdn.staticfile.org/highcharts/10.1.0/highcharts-3d.js"></script>

这里如果3d饼状图选中后会往下移动,导致错位,所以这里我们不允许饼状图选中。allowPointSelect: false,

function initChart() {
    // 修改3d饼图绘制过程
    const each = Highcharts.each
    const round = Math.round
    const cos = Math.cos
    const sin = Math.sin
    const deg2rad = Math.deg2rad
    Highcharts.wrap(Highcharts.seriesTypes.pie.prototype, 'translate', function (proceed) {
        proceed.apply(this, [].slice.call(arguments, 1))
        // Do not do this if the chart is not 3D
        if (!this.chart.is3d()) {
            return
        const series = this
        const chart = series.chart
        const options = chart.options
        const seriesOptions = series.options
        const depth = seriesOptions.depth || 0
        const options3d = options.chart.options3d
        const alpha = options3d.alpha
        const beta = options3d.beta
        var z = seriesOptions.stacking ? (seriesOptions.stack || 0) * depth : series._i * depth
        z += depth / 2
        if (seriesOptions.grouping !== false) {
            z = 0
        each(series.data, function (point) {
            const shapeArgs = point.shapeArgs
            var angle
            point.shapeType = 'arc3d'
            var ran = point.options.h
            shapeArgs.z = z
            shapeArgs.depth = depth * 0.75 + ran
            shapeArgs.alpha = alpha
            shapeArgs.beta = beta
            shapeArgs.center = series.center
            shapeArgs.ran = ran
            angle = (shapeArgs.end + shapeArgs.start) / 2
            point.slicedTranslation = {
                translateX: round(cos(angle) * seriesOptions.slicedOffset * cos(alpha * deg2rad)),
                translateY: round(sin(angle) * seriesOptions.slicedOffset * cos(alpha * deg2rad))
    (function (H) {
        H.wrap(Highcharts.SVGRenderer.prototype, 'arc3dPath', function (proceed) {
            // Run original proceed method
            const ret = proceed.apply(this, [].slice.call(arguments, 1))
            ret.zTop = (ret.zOut + 0.5) / 100
            return ret
    }(Highcharts))
    // 生成不同高度的3d饼图
    Highcharts.chart(document.getElementById('highEcharts'), {
        chart: {
            type: 'pie',
            animation: false,
            backgroundColor: 'rgba(0,0,0,0)',

                    const each = Highcharts.each
                    const points = this.series[0].points
                    each(points, function (p, i) {
                        p.graphic.attr({
                            translateY: -p.shapeArgs.ran
                        p.graphic.side1.attr({
                            translateY: -p.shapeArgs.ran
                        p.graphic.side2.attr({
                            translateY: -p.shapeArgs.ran
            options3d: {
                enabled: true,
                alpha: 65

                *  格式化函数可用的变量:this, 可以用 console.log(this) 来查看包含的详细信息

                {name: 'C类', y: 10, h: 32},
                {name: 'D类', y: 6, h: 45},
                {name: 'E类', y: 6, h: 45}

我们还可以使用自定义html来实现legend
