[GitHub] [incubator-echarts] x-strong opened a new issue #13657: Please add support for configuring color property by function for all chart type.
x-strong opened a new issue #13657:
URL: https://github.com/apache/incubator-echarts/issues/13657
### What problem does this feature solve?
Flexibly config & control chart color, and make chart much more readable and meaningful. for example, a bar chart( horizontal) showing kafka topics disk usage, if I can control / config the bars color by function, then I can set the bar color according to the usage percentage, 50% < green, 50% <= oringe < 70%, 70% <= yellow < 80%, 80% <= red. Why do I need to set colors like that? Here I'd like to introduce a concept that we can just call it "semantics color", and it includes two kind of colors, safe color (green, some what like the traffic light) and warn color(yellow, oringe and red). If so, user can easily and quickly differentiate the imortant part and focus on those disk over-use topics.
### What does the proposed API look like?
Color property can accept a functon which return the specific colors structure that match the chart type, and the function parameter is also specific to the chart type.
