Getting more experience with the oh-chart widget possibilities, I’m almost getting bold in trying things.
Currently, I’m trying to create something like a compass rose with using a gauge as graph and being fed by weather data. In this phase of development it looks like this,
Now, a classic compass needle needs to have two colors to know the actual direction is points to. Instead to make it somehow complicate with may two separate pointers and doing math, i was thinking about using gradient colors, as they are support by eCharts (Documentation - Apache ECharts).
Trying to adopt the syntax, I fail.
My pointer definition looks like this,
pointer: icon: path://M128.5,2.5 L110.5,128.5 L128.5,250.5 L146.5,128.5 L128.5,2.5 length: 150 width: 12 offsetCenter: - 0 - 75 itemStyle: color: type: linear x: 0 y: 0 x2: 0 y2: 1 colorStops: - - 0.5 - "#ff3300" - - 1 - "#ffffff"
But the effect is, that the pointer isn’t shown at all.
Anyone any idea?
