[Solved]-Highcharts percent view breaks with multiple series-Highcharts

Not totally sure I understand what you want, but here's two potential fixes:

Remove stacking: 'percent' from the plotOptions and the second graph will render proper as separate lines

Remove type: 'line' from the series and add type: 'column' to the chart if you want stacked percentage bar graph
