How to set an fillArea offset in HighCharts

Question

I try to set an reference value for a area-plot in higcharts. this should be similar to this example but with 100 as baseline. Because its hard to describe i attach a picture. I'm really lost on this topic, thanks for any help/hint in advance.

Answer 1

threshold was what im looking for. add it to the series, see jsfiddle

series: [{
    name: 'John',
    data: [105, 103, 104, 107, 102],
    threshold : 100
} ....
