[Solved]-Position events below analog area in Highcharts combined line/timeline chart-Highcharts

I can suggest two solutions:

• add a second yAxis and set heights for both y-axes:

   yAxis: [{
       height: '50%'
   }, {
       height: '50%',
       top: '50%'
   }],

API: https://api.highcharts.com/highcharts/yAxis.height

• change the y values for x-range series in the current implementation
