无法使react-chartjs选项生效

我很难过..."图表数据"有效,但不是"图表选项"。我必须在我的组件上使用.setState作为选项吗?

我也没有通过谷歌搜索看到任何完整的样本(如果我错了,请纠正我)。我想我很难搞清楚" React"做事方式......必须简单。我的代码如下。对不起它有多详细。

  var chartOptions = [
  {
      //Boolean - Show a backdrop to the scale label
      scaleShowLabelBackdrop : true,

      //String - The colour of the label backdrop
      scaleBackdropColor : "rgba(255,255,255,0.75)",

      // Boolean - Whether the scale should begin at zero
      scaleBeginAtZero : true,

      //Number - The backdrop padding above & below the label in pixels
      scaleBackdropPaddingY : 2,

      //Number - The backdrop padding to the side of the label in pixels
      scaleBackdropPaddingX : 2,

      //Boolean - Show line for each value in the scale
      scaleShowLine : true,

      //Boolean - Stroke a line around each segment in the chart
      segmentShowStroke : true,

      //String - The colour of the stroke on each segement.
      segmentStrokeColor : "#fff",

      //Number - The width of the stroke value in pixels
      segmentStrokeWidth : 2,

      //Number - Amount of animation steps
      animationSteps : 100,

      //String - Animation easing effect.
      animationEasing : "easeOutBounce",

      //Boolean - Whether to animate the rotation of the chart
      animateRotate : true,

      //Boolean - Whether to animate scaling the chart from the centre
      animateScale : false,

      //String - A legend template
      legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"

      pointDotRadius : 3,

      //Number - Pixel width of point dot stroke
      pointDotStrokeWidth : 1,

      //Number - amount extra to add to the radius to cater for hit detection outside the drawn point
      pointHitDetectionRadius : 20,

删除“chartOptions”和“chartOptionsRadarInit”变量的“[”和“]”,然后它就可以了:/
