图表渲染器,采用 echarts 渲染,配置格式跟 echarts 相同,[echarts配置文档](http://echarts.baidu.com/option.html#title)
## 基本用法
```schema:height="350" scope="body"
{
"type": "chart",
"api": "https://houtai.baidu.com/api/mock2/chart/chart",
"interval": 5000
}
```
## 配置静态配置项
通过配置`"config": {}`,可以配置`echarts`配置
```schema:height="350" scope="body"
{
"type": "chart",
"config": {
"title": {
"text": "极坐标双数值轴"
},
"legend": {
"data": [
"line"
]
},
"polar": {
"center": [
"50%",
"54%"
]
},
"tooltip": {
"trigger": "axis",
"axisPointer": {
"type": "cross"
}
},
"angleAxis": {
"type": "value",
"startAngle": 0
},
"radiusAxis": {
"min": 0
},
"series": [
{
"coordinateSystem": "polar",
"name": "line",
"type": "line",
"showSymbol": false,
"data": [
[

"animationDuration": 2000
},
"clickAction": {
"actionType": "dialog",
"dialog": {
"title": "详情",

"tpl": "<span>当前选中值 ${value|json}<span>"
},
{
"type": "chart",

}
]
}
}
}
```
## 配置图表点击行为
可以通过配置`"clickAction": {}`来指定图表节点的点击行为支持amis的[行为](./action)。

```schema:height="350" scope="body"
{
"type": "chart",
"config": {

## 远程拉取动态配置项
配置`api`,来远程拉取图标配置
```schema:height="350" scope="body"
{
"type": "chart",
"api": "https://houtai.baidu.com/api/mock2/chart/chart1"
}
```
## 通过组件间联动,更新图表
```schema:height="350" scope="body"
[
{
"type": "form",
"title": "过滤条件",
"target": "chart1,chart2",
"submitOnInit": true,
"className": "m-b",
"wrapWithPanel": false,
"mode": "inline",
"controls": [
{
"type": "date",
"label": "开始日期",
"name": "starttime",
"value": "-8days",
"maxDate": "${endtime}"
},
{
"type": "date",
"label": "结束日期",
"name": "endtime",
"value": "-1days",
"minDate": "${starttime}"
},
{
"type": "text",
"label": "条件",
"name": "name",
"addOn": {
"type": "submit",
"label": "搜索",

},
{
"type": "chart",
"name": "chart2",
"initFetch": false,
"api": "https://houtai.baidu.com/api/mock2/chart/chart2?name=$name"
}
