ssmd-条形图echarts value配置项内容和展示

快速配置条形图，支持数值和百分比

      // 是否显示百分比，通过调整改参数控制显示的是数值还是百分比
const isPercent = false;
// 数据配置：[y轴类目名，类目值]
const dataConfig = [
    ['类目1', 10],
    ['类目2', 20],
    ['类目3', 30],
    ['类目4', 40]
];

const total = dataConfig.reduce((t, v) => t + v[1], 0);
const yData = dataConfig.map(item => item[0]);
const seriesData = dataConfig.map(item => item[1]);
