有没有办法在渲染后用新数据更新径向（或圆形）条形图？

Question

我想显示径向（或圆形）柱状高图 https://www.highcharts.com/docs/chart-and-series-types/radial-bar-chart

由于数据的计算时间较长，我想先显示图表，然后在准备好后更新数据。

默认绘制没有值的图表，但经过一些耗时的计算后会更新。我试过如下没有徒劳。

我尝试使用 radialGraph.series.update();函数但出现错误 Uncaught TypeError: radialGraph.series.update is not a function.

有人知道怎么做吗？谢谢。

// Loads default values

radialGraph = Highcharts.chart('container', {
    colors: ['#FFD700', '#C0C0C0', '#CD7F32'],
    chart: {
        type: 'column',
        inverted: true,
        polar: true
    },
    title: {
        text: 'Winter Olympic medals per existing country (TOP 5)'
    },
    tooltip: {
        outside: true
    },

        size: '85%',
        innerSize: '20%',

            align: 'right',
            useHTML: true,
            allowOverlap: true,
            step: 1,
            y: 3,
            style: {
                fontSize: '13px'
            }
        },
        lineWidth: 0,
        categories: [

    },

            pointPadding: 0,
            groupPadding: 0.15
        }
    },
    series: [{
        name: 'Gold medals',
        data: [0, 0, 0]
    }, {
        name: 'Silver medals',
        data: [0, 0, 0]
    }, {
        name: 'Bronze medals',
        data: [0, 0, 0]
    }]
});



// After some time-consuming computations, update the series data with the below sample.

    radialGraph.series.update([{
        name: 'Gold medals',
        data: [132, 105, 92]
    }, {
        name: 'Silver medals',
        data: [125, 110, 86]
    }, {
        name: 'Bronze medals',
        data: [111, 90, 60]
    }]);
    
    // I tried updating as above but keep getting: Uncaught TypeError: radialGraph.series.update is not a function

series 属性是一个数组。要更新它，您可以使用 chart.update 方法：

    radialGraph.update({
        series: [{
            name: 'Gold medals',
            data: [132, 105, 92]
        }, {
            name: 'Silver medals',
            data: [125, 110, 86]
        }, {
            name: 'Bronze medals',
            data: [111, 90, 60]
        }]
    });

或通过series.setData或series.update方法更改每个系列的数据：

    const series = radialGraph.series;
    
    series[0].setData([132, 105, 92], false);
    series[1].setData([125, 110, 86], false);
    series[2].setData([111, 90, 60]);

Is there a way to update with new data a Radial (or Circular) bar chart after rendering?
