I'm exploring Highcharts and it seems like a very comprehensive package! I have a question regarding legend colors.
I notice that when I use a linear color gradient for a line, the color next to the legend (I believe it's called the symbolColor) may or may not show up, depending on the format I use:
1) symbolColor works fine: linearGradient: [ 00, 00, 00, 350 ]
2) symbolColor doesn't show up: linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 }
I'd rather use the second format; it's easier and the first is not responsive.
Should the symbolColor always show up and this is an obscure issue/bug? Or am I doing something wrong? I also just noticed that if the marker is enabled in the plotOptions for series, symbolColor works fine with the second format. But I have many data points and don't want to use markers.
The fiddle graph has two lines -- purple and green -- and while the purple symbolColor using method (1) looks fine, you'll notice that the green symbolColor using method (2) doesn't show up.
