Echarts自定义属性
功能概述
ECharts 类可视化组件提供了自定义属性设置，支持用户手动更改 ECharts option，使用 JS 代码进行深度定制。
自定义属性窗口编写区可直接编写JS代码，具体配置项与 ECharts 一致，请您参考 ECharts 官网 https://echarts.apache.org/zh/option.html#title。
窗口右上角的查看配置项按钮可查看产品图表中默认的配置项，定制内容会覆盖默认生成的内容。
示例
例如使用JS 代码自定义属性修改了柱状图的显示样式，预览效果如下：
具体代码如下，供您参考。
let datas = []
let cates = []
let comebineData = []
const total = 70000
option.xAxis.data.forEach(item => {
cates.push(item.value)
})
option.series[0].data.forEach(item => {
datas.push(item.value)
})
cates.forEach((item, index) => {
let tmp = { name: item, value: datas[index] }
comebineData.push(tmp)
})
