自定义序列有的 Item 没有渲染echarts group配置项内容和展示
Pattern serie，data 中有三个 item，目前只渲染一个，另两个 rl,sl 为空的没有渲染，而且经测试并没有进到 renderItem
配置项如下
const LINE_STYLE = {fill: null, stroke: '#da9be8', lineWidth: 2};
const DOT_LINE_STYLE = {lineDash: [3, 3], lineWidth: 2, opacity: .8};
const EMPPHASIS_STYLE = {lineWidth: 3, opacity: 1};
function buildLine({value, itemStyle:{normal, emphasis = {}}}, api) {
const [x1, y1] = api.coord([value[0], value[1]]);
const [x2, y2] = api.coord([value[2], value[3]]);
let {color, borderColor, borderWidth} = normal;
const style = api.style({fill: color, stroke: borderColor, lineWidth: borderWidth, ...DOT_LINE_STYLE});
let {color: fill, borderColor: stroke, borderWidth: lineWidth} = emphasis;
const styleEmphasis = api.styleEmphasis({fill, stroke, lineWidth, lineDash: [3, 3], ...EMPPHASIS_STYLE});
return {
type: 'line',
shape: {
x1, y1, x2, y2
},
style,
styleEmphasis
};
}
