[Solved]-Highcharts - Area Chart - Stacking with series containing negative and positive values-Highcharts

i was able to workaround it with the help of explanation given in this stackoverflow answer, though in my workaround at june, 19 14:40 and june, 19 16:20, there is a single negative point of con with positives before and after it. this can cause issue when you have multiple series of such kind i.e. which one to stack above the other will be a question.
