[Solved]-High charts Issue with stock bar chart multiple line series-Highcharts

Live example with the issue: http://jsfiddle.net/BlackLabel/zwsLxyac/

You have unsorted data which causes Highcharts error #15: https://assets.highcharts.com/errors/15/

You need to sort your data before it is passed to a chart:

datas.forEach((series, index) => {
    series.data.sort((a, b) => a[0] - b[0]);
});
