Вопрос по css, javascript – Градиентная заливка на линейной диаграмме (Highcharts)

14

Мне не удалось найти документацию, которая позволила бы мне объединить внешний вид этих двух диаграмм:

Нерегулярный график времени
График линии / времени с градиентной заливкой

Я пытаюсь поместить градиентную заливку под каждую из 3 строк на нерегулярной временной диаграмме.

Вот, насколько я понял:http://jsfiddle.net/WNDUH/

Любая помощь будет оценена!

а затем определить тип и fillColor каждой серии.

Отлично. Это было недостающее звено, которое я искал! Спасибо за помощь. Jeremy Penrod
