Solution

  • You can create mocked line series and link areaspline ones to them. Example:

      series: [{
        name: 'Tokyo',
        dashStyle: 'longdash',
        type: 'line',
        id: 'line1'
      }, {
        name: 'London',
        dashStyle: 'longdash',
        type: 'line',
        id: 'line2'
      }, {
        linkedTo: 'line1',
        name: 'Tokyo',
        ...
    
      }, {
        linkedTo: 'line2',
        name: 'London',
        ...
      }]
