如何使 react-highchart 线型保持固定？

Question

每次我在我的textarea中输入一些东西时，下图中的黑线不断地重新渲染数据。如何让它保持固定？下面是显示图表 table 和文本区域代码的代码。我正在使用 CKEditor js 库来显示来自 textarea 的工具。我还对显示的图表使用了 react-highcharts。

谢谢。

为我的 HIGHCHART 配置

const config = {
  /* HighchartsConfig */

title: {
    text: ''
},

xAxis: {
    tickLength: 75,
    categories: [month1, month2, month3, month4],
    labels: {
      style: {
        color: 'black',
        fontSize:'13px'

      },
      formatter: function(){

      return '<span style="margin-right: 9px">' + this.chart.series[0].options.stack + '</span><span>' + this.chart.series[1].options.stack + 
      '</span><br /><div style="text-align:center"> <br />' + this.value + '</div> '
    },    
    useHTML: true
  } 
},

yAxis: [{ //--- Primary yAxis
  title: {
      text: 'Bugs, Questions And Enhancements'
  }
}, { //--- Secondary yAxis
  title: {
      text: 'Total Open'
  },
  opposite: true
}],

tooltip: {
    formatter: function () {
        return '<b>' + this.x + '</b><br/>' +
            this.series.name + ': ' + this.y + '<br/>' +

        }
    },
      itemStyle: {

          fontSize: '17px'
      }
},

Answer 1

您正在使用 'react-highcharts' 包装器，这会导致在每次 setState 后重新绘制图表。您可以将 line 系列的 animation 选项设置为 false，但更好的解决方案是使用 'highcharts-react-official' 包装器，它仅在图表选项发生变化时更新图表。

{
  yAxis: 1,
  type: "line",
  name: "Total Open",
  color: "#2C2727",
  data: [3, 7, 3, 25],
  lineWidth: 4.5,
  animation: false,  // new property
  marker: {
    enabled: false
  }
}
