how to create a group or similar on the data on the left of the graph, so that the height of the yield and consumed from pv graphs is not the same as the total consumption.

const options = {
   chart: {
     height: 500,
     type: 'line',
     stacked: false,
     zoom: {
       enabled: false,
     },
   },
   stroke: {
     width: 0,
   },

   xaxis: {
     categories: categoriesData,
     tickPlacement: 'between',
   },
   yaxis: [
     {},
     {},
     {},
     {
       tooltip: {
         enabled: true,
       },
       showAlways: true,
       opposite: true,
       axisTicks: {
         show: true,
       },
     },
   ],
   legend: {
     position: 'bottom',
     fontFamily: 'Inter',
     fontSize: '15px',
     itemMargin: {
       horizontal: 10,
       vertical: 5,
     },
   },
 };
