在Highcharts 3D散點圖中重繪問題

Question

在這裏，我正在研究Highcharts 3D散點圖，基於樣本jsfiddle。在小提琴中，我用來重繪圖表，同時清空包含圖表的分區，分散點被移除，但3D容器不會被移除，因此圖表不會重新繪製。

JavaScript代碼：

var chart = new Highcharts.Chart({ 
     chart: { 
      renderTo: 'container', 
      type: 'scatter', 
      width: 500, 
      height: 550, 
      marginTop:150, 
      margin: 100, 
      options3d: { 
       enabled: true, 
       drag: { 
         enabled: true, 
        flipAxes: true, 
        snap: 15, 
        animateSnap: true 
           }, 
       alpha: 15, 
       beta: 30, 
       depth: 300, 
       viewDistance: 5, 
       fitToPlot: false, 
       frame: { 
        bottom: { size: 1, color: 'rgba(0,0,0,0.02)' }, 
        back: { size: 1, color: 'rgba(0,0,0,0.04)' }, 
        side: { size: 1, color: 'rgba(0,0,0,0.06)' } 
       } 
      } 
     }, 
     title: { 
      text: 'Draggable box' 
     }, 
     subtitle: { 
      text: 'Click and drag the plot area to rotate in space' 
     }, 
     plotOptions: { 
      scatter: { 
       width: 10, 
       height: 10, 
       depth: 10 
      } 
     }, 
     yAxis: { 
      min: 0, 
      max: 10, 
      title: null 
     }, 
     xAxis: { 
      min: 0, 
      max: 10, 
      gridLineWidth: 1 
     }, 
     zAxis: { 
      min: 0, 
      max: 10, 
      showFirstLabel: false 
     }, 
     legend: { 
      enabled: false 
     }, 
     series: [{ 
      name: 'Reading', 
      colorByPoint: true, 
      data: [[1, 6, 5], [8, 7, 9], [1, 3, 4], [4, 6, 8], [5, 7, 7], [6, 9, 6], [7, 0, 5], [2, 3, 3], [3, 9, 8], [3, 6, 5], [4, 9, 4], [2, 3, 3], [6, 9, 9], [0, 7, 0], [7, 7, 9], [7, 2, 9], [0, 6, 2], [4, 6, 7], [3, 7, 7], [0, 1, 7], [2, 8, 6], [2, 3, 7], [6, 4, 8], [3, 5, 9], [7, 9, 5], [3, 1, 7], [4, 4, 2], [3, 6, 2], [3, 1, 6], [6, 8, 5], [6, 6, 7], [4, 1, 1], [7, 2, 7], [7, 7, 0], [8, 8, 9], [9, 4, 1], [8, 3, 4], [9, 8, 9], [3, 5, 3], [0, 2, 4], [6, 0, 2], [2, 1, 3], [5, 8, 9], [2, 1, 1], [9, 7, 6], [3, 0, 2], [9, 9, 0], [3, 4, 8], [2, 6, 1], [8, 9, 2], [7, 6, 5], [6, 3, 1], [9, 3, 1], [8, 9, 3], [9, 1, 0], [3, 8, 7], [8, 0, 0], [4, 9, 7], [8, 6, 2], [4, 3, 0], [2, 3, 5], [9, 1, 4], [1, 1, 4], [6, 0, 2], [6, 1, 6], [3, 8, 8], [8, 8, 7], [5, 5, 0], [3, 9, 6], [5, 4, 3], [6, 8, 3], [0, 1, 5], [6, 7, 3], [8, 3, 2], [3, 8, 3], [2, 1, 6], [4, 6, 7], [8, 9, 9], [5, 4, 2], [6, 1, 3], [6, 9, 5], [4, 8, 2], [9, 7, 4], [5, 4, 2], [9, 6, 1], [2, 7, 3], [4, 5, 4], [6, 8, 1], [3, 4, 0], [2, 2, 6], [5, 1, 2], [9, 9, 7], [6, 9, 9], [8, 4, 3], [4, 1, 7], [6, 2, 5], [0, 4, 9], [3, 5, 9], [6, 9, 1], [1, 9, 2]] 
     }] 
    }); 

請建議重繪三維散點圖的方法。

Answer 1

移動方法外的顏色設置將解決您的問題。在這裏查看更多信息：http://forum.highcharts.com/highcharts-usage/pie-char-uncaught-typeerror-a-indexof-is-not-a-function-t33161/

我還將圖表移動到方法外，以便可以調用destroy()。這將防止內存泄漏。

var chart; 

// Give the points a 3D feel by adding a radial gradient 
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) { 
    return { 
     radialGradient: { 
      cx: 0.4, 
      cy: 0.3, 
      r: 0.5 
     }, 
     stops: [ 
      [0, color], 
      [1, Highcharts.Color(color).brighten(-0.2).get('rgb')] 
     ] 
    }; 
}); 

function scatterChart(Data) { 
    // Set up the chart 
    chart = new Highcharts.Chart({ 
     chart: { 
      renderTo: 'container', 
      type: 'scatter', 
      width: 500, 
      height: 550, 
      marginTop:150, 
      margin: 100, 
      options3d: { 
       enabled: true, 
       drag: { 
         enabled: true, 
        flipAxes: true, 
        snap: 15, 
        animateSnap: true 
           }, 
       alpha: 15, 
       beta: 30, 
       depth: 300, 
       viewDistance: 5, 
       fitToPlot: false, 
       frame: { 
        bottom: { size: 1, color: 'rgba(0,0,0,0.02)' }, 
        back: { size: 1, color: 'rgba(0,0,0,0.04)' }, 
        side: { size: 1, color: 'rgba(0,0,0,0.06)' } 
       } 
      } 
     }, 
     title: { 
      text: 'Draggable box' 
     }, 
     subtitle: { 
      text: 'Click and drag the plot area to rotate in space' 
     }, 
     plotOptions: { 
      scatter: { 
       width: 10, 
       height: 10,

      title: null 
     }, 
     xAxis: { 
      min: 0,

      gridLineWidth: 1 
     }, 
     zAxis: {

scatterChart(scatterData); 
chart.destroy(); 
scatterChart(scatterData);
