设置数据条颜色（推荐）

let yData = [{value: 500,time: '2012-11-12',itemStyle: //设置数据条颜色{normal: { color: 'red' }}},{value: 454,time: '2020-5-17'},{value: 544,time: '2022-1-22'},{value: 877,time: '2013-1-30'}, {value: 877,time: '2012-11-12'}]

设置数据条颜色2 （不推荐）

itemStyle:{normal: {color: pamars => {let colorList = ['red', 'yellow', 'blue', 'green', 'pink']return colorList[pamars.dataIndex]}}}

 series:   [{name: '图例',type: 'bar',//图表类型data: yData,//图标数据barWidth: 25//数据条宽度}]
