Gradient Fill na wykresie linia (Highcharts)

Question

jakim byłem w stanie znaleźć w dokumentacji, że pozwolił mi połączyć wygląd tych dwóch wykresów:

Irregular Time Chart
Line/Time Chart with Gradient Fill

Ja próbuje umieścić gradient wypełnij pod każdą z 3 linii na nieregularnym wykresie czasowym.

Oto ile mam: http://jsfiddle.net/WNDUH/

Każda pomoc będzie mile widziana!

Answer 1

Spróbuj przenieść obiekt obszaru do parametru plotOptions, a następnie zdefiniować typ i fillColor każdej serii.
