I’m currently using

when I try to click and drag the point of the line it gives
Draggable line series gives a TypeError: Cannot read properties of undefined (reading ‘chart’)

My settings in the series is

  series: [
    {
      type: "candlestick",
      name: "Ethereum",
      id: "ethereum",
      data: ohlcdata,
    },
    {
      dragDrop: {
        draggableY: true,
      },
      type: "line",
      name: "Trend Line",
      data: [
        [1060646400000, 0.6848],
        [1209010862151.3945, 0.8521739130434782],
      ],
      yAxis: 0,
    },
    {
      type: "macd",
      id: "oscillator",
      linkedTo: "ethereum",
      yAxis: 1,
      params: {
        period: 26,
        signalPeriod: 9,
        shortPeriod: 12,
      },
    },
  ],

as per documentation but this gives me error.

I also try to import the https://github.com/highcharts/draggable-points/blob/master/draggable-points.js in the script the typeerror was gone but still not working
