使用
1. 在 html 中引入 echarts资源包
<script src="echarts.min.js"></script>
<!-- <script src="https://cdn.bootcdn.net/ajax/libs/echarts/5.1.2/echarts.min.js"></script> -->2. 注册
import { register as registerEcharts } from "@meta2d/chart-diagram";
registerEcharts();3. 添加图表图元
const pen = {
name: "echarts",
x: 100,
y: 100,
width: 500,
height: 200,
externElement: true,
disableAnchor: true,
echarts: {
theme: "le-dark",
option: {
grid: {
bottom: 20,
left: 20,
right: 20,
top: 100,
containLabel: true,
},
title: {
text: "标题",
textStyle: {
fontSize: 16,
},
padding: 5,
top: 16,
left: 16
},
// 图例
legend:{
data:['系列1'], // 该数组中的内容要与series中的每项的name对应
textStyle:{
fontSize: 12,
},
itemWidth: 25,
itemHeight: 14,
top: 48,
padding:5,
},
// 提示框组件
tooltip: {
backgroundColor: 'rgba(24,24,24,0.95)',
borderColor: 'rgba(24,24,24,0.95)',
trigger: 'axis',
axisPointer: {
type: "shadow"
},
textStyle: {

fontWeight: 400
}
},
fontSize: 10,
xAxis: {
type: 'category',
data: ['1月', '2月', '3月', '4月', '5月', '6月'],
axisLabel: {
fontSize: 12,
margin: 10
},
axisTick:{
alignWithLabel:true
}
},
yAxis: {
type: 'value',

},
splitNumber: 2,
minInterval: 50,
axisLabel: {
fontSize: 12,
margin: 10,
textStyle: {

},
},
},
series: [
{
name:"系列1",
type: 'line',
data: [40, 20, 90, 60, 70, 80],
lineStyle:{
width: 2
},
symbolSize: 5, //小圆点的大小
},
],
},
}
};
meta2d.addPen(pen);
meta2d.inactive();4. 结果
样式修改
选中图表图元，点击数据，点击echarts配置按钮。
按照echarts官方options配置，修改配置项后，点击运行可以查看效果，确定后点击关闭。
数据更新
const pen = {
name: "echarts",
x: 100,
y: 100,
width: 400,
height: 300,
externElement: true,
disableAnchor: true,
echarts: {
option: {
xAxis: {
type: "category",
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
},
yAxis: {
type: "value",
},
series: [
{
data: [820, 932, 901, 934, 1290, 1330, 1320],
type: "line",
},
],
},
},
};
meta2d.addPen(pen);
//更新整个数据
meta2d.setValue({
id: pen.id,
'echarts.option.series.0.data':[11,12,13,14,15,16,17]
});
//更新一个数据点
meta2d.setValue({
id: pen.id,
'echarts.option.series.0.data.2':133
});
//更新x轴
meta2d.setValue({
id: pen.id,
'echarts.option.xAxis.data':['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月']
});echarts地图
echarts官方地图文档说明： echarts地图
echarts.geoUrl 是一个请求地图数据的地址（也可以直接配置地图json数据，echarts.geoJson，但是地图数据一般很大，所以不推荐直接配置。）
echarts.geoName 是给geoUrl请求的数据命名，配置这两个数据，meta2d底层就会完成echarts地图的注册。
options.map直接配置geoName就可以了。
//echarts地图
