基础散点图
散点图，也是一种常见的图表类型。散点图由许多“点”组成，有时，这些点用来表示数据在坐标系中的位置（比如在笛卡尔坐标系下，表示数据在 x 轴和 y 轴上的坐标；在地图坐标系下，表示数据在地图上的某个位置等）；有时，这些点的大小、颜色等属性也可以映射到数据值，用以表现高维数据

export default {

app.config.globalProperties.$san = (id: any) => {
var chartDom = document.getElementById(id)!;
if (chartDom == null) {
return;
}
echarts.dispose(chartDom);
var myChart = echarts.init(chartDom, "", { width: 500, height: 300 });
var option = {
xAxis: {
type: "value",
