This is my example: http://jsfiddle.net/994pvk8o/
When I add negative values to the chart, at X point 194, P1 and P3 = 1, but P2=-1. The total sum of the values is 1, and is actually hiding P1 and P2. (Click on P2 to disable it).
So, I want the negative values to be separately stacked from the positive values. We won't get overlapping areas then.
Is there an option that I can use with highcharts to do this? I tried:
plotOptions:{
series:{
threshold: -1
}
}
but, no luck.
