[GitHub] [incubator-echarts] bt4baidu opened a new issue #12840: [Candlestick][itemStyle]Cannot customize color and color0 by callback function
bt4baidu opened a new issue #12840:
URL: https://github.com/apache/incubator-echarts/issues/12840
### What problem does this feature solve?
There are special sticks, for example limitUP/ limitDOWN which is meaningful to the market trend.
It will be very helpful if we can set different color for such sticks, for example:
{
up: color red,
limitUP: color yellow,
down: color green,
limitDOWN: color: blue
}
某些K线对行情发展有重要的意义，如涨停/跌停，希望可以给这些K线设置不同的颜色，给用户一目了然的提示，如可以设置：
{
上涨：红色，
涨停：黄色，
下跌：绿色，
跌停：蓝色
}
### What does the proposed API look like?
color and color0 can be customized by a callback function, for example:
```javascript
series: [
{
name: 'Dow-Jones index',
type: 'candlestick',
data: data.values,
itemStyle: {
color: function(param){...},
color0: function(param){...},
}
}]
```

Find a way to realize this request, code example as following:
```javascript
if (pc && c === h && ((c - pc) * 100 / pc).toFixed(2) >= 9.9)
values.push({
value: [o, c, l, h],
itemStyle: {
color: '#FFFF00',
color0: 'green',
borderColor: null,
borderColor0: null
}
})
else
values.push([o, c, l, h])
```
Close this issue.
