图表渲染器,采用 echarts 渲染,配置格式跟 echarts 相同,[echarts 配置文档](https://echarts.apache.org/zh/option.html#title)
2020-07-28 10:03:53 +08:00
## 基本用法
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "chart",
"api": "/api/mock2/chart/chart",
2020-07-28 10:03:53 +08:00
"interval": 5000
}
```
2021-01-19 16:55:09 +08:00
api 返回支持两种格式,一种是直接返回完整 echarts 配置,数据包含在配置里,具体格式请参考后面的静态数据写法,另一种是返回纯数据,具体请参考动态数据写法。
2020-07-28 10:03:53 +08:00
2021-01-19 16:55:09 +08:00
## 静态数据
2021-01-19 16:51:48 +08:00
2021-01-19 16:55:09 +08:00
`config` 里填写完整的 echarts 配置,这里的数据是静态的。
2020-07-28 10:03:53 +08:00
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "chart",
"config": {
"title": {
"text": "极坐标双数值轴"
},
"legend": {
"data": [
"line"
]
},

"54%"
]
},

}
},

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

},

2020-07-28 10:03:53 +08:00
}
]
}
}
}
```
2021-01-19 16:51:48 +08:00
## 动态数据
如果要实现动态数据,需要在 config 中做调整,比如将前面的例子改成如下写法
```schema: scope="body"
{
"type": "chart",
"api": "/api/mock2/chart/chartData",
2021-01-19 16:51:48 +08:00
"config": {
"xAxis": {
"type": "category",
"data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
},
"yAxis": {
"type": "value"
},
"series": [{
"data": "${line || []}",
2021-01-19 16:51:48 +08:00
"type": "line"
}]
}
}
```
> Echarts 中有些配置不能为未定义,所以要使用变量,最好使用类似上面的 `${line || []}` 写法配置默认值,保证在数据加载完前渲染也不会报错
其中 api 返回内容是如下写法,可以看到通过[数据映射](../../docs/concepts/data-mapping)语法,我们可以将 api 放回结果中的 line 字段作为折线的数据。
2021-01-19 16:51:48 +08:00
```json
{
"status": 0,
"msg": "ok",
"data": {
"line": [65, 63, 10, 73, 42, 21]
}
}
```
除了 `config` 中的 `data``config` 里的其它属性也都支持数据映射,还能支持数据映射中的各种过滤器。
### 使用上层数据接口
有时候数据是在上层获取的,比如通过 service 中返回了数据,这时需要通过 `trackExpression` 来指定跟踪什么数据,比如下面的例子,数据是从 service 获取的就需要配置 `trackExpression`
> 如果`trackExpression` 追踪的数据是**对象数据**,可以使用[数据映射](../../docs/concepts/data-mapping)的`json`方法将数据序列化之后再比较,例如`"trackExpression": "${fieldToTrack|json}"`
2021-01-19 16:51:48 +08:00
```schema: scope="body"
{
"type": "service",
"api": "/api/mock2/chart/chartData",
2021-01-19 16:51:48 +08:00
"interval": 3000,
"body": [
{
"type": "chart",
"trackExpression": "${line}",
"config": {
"xAxis": {
"type": "category",
"data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
},
"yAxis": {
"type": "value"
},
"series": [{
"data": "${line || []}",
2021-01-19 16:51:48 +08:00
"type": "line"
}]
}
}
]
}
```

## 配置图表点击行为
2020-11-12 15:26:44 +08:00
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)。
然后在配置的行为中可以通过 [数据链](../../docs/concepts/datascope-and-datachain) 获取到 [echarts 鼠标事件](https://echarts.apache.org/zh/api.html#events.%E9%BC%A0%E6%A0%87%E4%BA%8B%E4%BB%B6.click) 的值,例如下面例子中可以通过`${value|json}`获取到点击节点的`传入的数据值`
2020-07-28 10:03:53 +08:00
> 点击下面坐标中的节点查看效果!
```schema: scope="body"
2020-07-28 10:03:53 +08:00

}
```
具体能拿到的参数请参考 [Echarts](https://echarts.apache.org/handbook/zh/concepts/event#%E9%BC%A0%E6%A0%87%E4%BA%8B%E4%BB%B6%E7%9A%84%E5%A4%84%E7%90%86) 的文档,官方定义如下
```typescript
type EventParams = {
// 当前点击的图形元素所属的组件名称,
// 其值如 'series'、'markLine'、'markPoint'、'timeLine' 等。
componentType: string;
// 系列类型。值可能为:'line'、'bar'、'pie' 等。当 componentType 为 'series' 时有意义。
seriesType: string;
// 系列在传入的 option.series 中的 index。当 componentType 为 'series' 时有意义。
seriesIndex: number;
// 系列名称。当 componentType 为 'series' 时有意义。
seriesName: string;
// 数据名,类目名
name: string;
// 数据在传入的 data 数组中的 index
dataIndex: number;
// 传入的原始数据项
data: Object;
// sankey、graph 等图表同时含有 nodeData 和 edgeData 两种 data
// dataType 的值会是 'node' 或者 'edge',表示当前点击在 node 还是 edge 上。
// 其他大部分图表中只有一种 datadataType 无意义。
dataType: string;
// 传入的数据值
value: number | Array;
// 数据图形的颜色。当 componentType 为 'series' 时有意义。
color: string;
};
```

## 远程拉取动态配置项
配置`api`,来远程拉取图标配置
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "chart",
"api": "/api/mock2/chart/chart1"
2020-07-28 10:03:53 +08:00
}
```
## 通过组件间联动,更新图表
```schema: scope="body"
2020-07-28 10:03:53 +08:00
[
{
"type": "form",
"title": "过滤条件",
"target": "chart1,chart2",
"submitOnInit": true,
"className": "m-b",
"wrapWithPanel": false,
"mode": "inline",
"body": [
2020-07-28 10:03:53 +08:00
{
"type": "input-date",
2020-07-28 10:03:53 +08:00
"label": "开始日期",
"name": "starttime",
"value": "-8days",
"maxDate": "${endtime}"
},
{
"type": "input-date",
2020-07-28 10:03:53 +08:00
"label": "结束日期",
"name": "endtime",
"value": "-1days",
"minDate": "${starttime}"
},
{
"type": "input-text",
2020-07-28 10:03:53 +08:00
"label": "条件",
"name": "name",
"addOn": {
"type": "submit",
"label": "搜索",
"level": "primary"
}
}
],
"actions": []
},
{
"type": "divider"
},
{
"type": "grid",
"className": "m-t-lg",
"columns": [
{
"type": "chart",
"name": "chart1",
"initFetch": false,
"api": "/api/mock2/chart/chart?name=$name&starttime=${starttime}&endtime=${endtime}"
2020-07-28 10:03:53 +08:00
},
{
"type": "chart",
"name": "chart2",
"initFetch": false,
"api": "/api/mock2/chart/chart2?name=$name"
2020-07-28 10:03:53 +08:00
}
]
}
]
```
## 对函数配置的特殊支持
ECharts 中有些配置项可以写函数,比如 formatter 和 sort但在 JSON 里无法写函数,因此我们做了特殊支持,将看起来像函数的字符串转成了函数:
```schema: scope="body"
{
"type": "chart",
"config": {
"legend": {
"formatter": "function (name) { return 'Legend ' + name;}"
},
"dataset": {
"source": [["type","2012","2013","2014","2015","2016"],["Forest",320,332,301,334,390],["Steppe",220,182,191,234,290],["Desert",150,232,201,154,190],["Wetland",98,77,101,99,40]]
},
"xAxis": {
"type": "category",
"axisTick": {
"show": false
}
},
"yAxis": {},
"series": [{"type":"bar","seriesLayoutBy":"row"},{"type":"bar","seriesLayoutBy":"row"},{"type":"bar","seriesLayoutBy":"row"},{"type":"bar","seriesLayoutBy":"row"}]
}
}
```
## 使用地图
从 amis 1.1.0 版本开始ECharts 版本升级到 5.0.0,为了规避政策风险,在这个版本删除了之前的地图 geojson如果需要这个功能需要手动引入。
方法是去 `https://github.com/apache/echarts/tree/master/test/data/map/js` 下载 `china.js``world.js`
对于 npm 版本,直接 `import` 这两个文件就行。
对于 JS SDK 版本,需要先加入如下代码如下方式:
```javascript
window.echarts = amisRequire('echarts');
```
然后通过 script 标签引入这两个文件,或者用下面的新版方法
## 地图配置
> 2.4.1 及以上版本
新增了 `mapURL``mapName` 两个配置项
```schema: scope="body"
{
"type": "chart",
"mapURL": "/api/map/HK",
"mapName": "HK",

## 加载百度地图
配置 `loadBaiduMap` 后会加载百度地图,需要配置 `ak`
```schema: scope="body"
{
"type": "chart",
"loadBaiduMap": true,
"ak": "LiZT5dVbGTsPI91tFGcOlSpe5FDehpf7",
"config": {
"bmap": {
"center": [116.414, 39.915],
"zoom": 14,
"roam": true
}
}
}
```
## 动态处理 echart 配置
echarts 的 config 一般是静态配置的,支持简单的数据映射。如果你觉得还不够灵活可以通过自己手写逻辑代码来完成配置。
通过配置 dataFiler 来处理。
```schema: scope="body"
{
"type": "chart",
"data": {
"line": [65, 63, 10, 73, 42, 21],
"line2": [22, 33, 90, 20, 11, 33]
},
"config": {
"xAxis": {
"type": "category",
"data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
},
"yAxis": {
"type": "value"
}
},
"dataFilter": "config.series = [];Object.keys(data).forEach(function(key) {config.series.push({data: data[key], type: 'line'})})"
}
```

## 动作表
2022-11-01 19:59:23 +08:00
当前组件对外暴露以下特性动作,其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作,动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数,详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。
| 动作名称 | 动作配置 | 说明 |
| -------- | -------------------------- | ------------------------------------------ |
| reload | - | 刷新(重新加载) |
| setValue | `value: object` 更新的数据 | 更新数据,等于更新图表所依赖数据域中的变量 |
2022-11-01 19:59:23 +08:00
2.4.1 及以上版本,除了以上动作,还支持直接触发[ECharts 组件行为](https://echarts.apache.org/handbook/zh/concepts/event/#%E4%BB%A3%E7%A0%81%E8%A7%A6%E5%8F%91-echarts-%E4%B8%AD%E7%BB%84%E4%BB%B6%E7%9A%84%E8%A1%8C%E4%B8%BA),即通过`actionType`指定行为名称,行为配置通过`args: {动作配置项名称: xxx}`来配置具体的参数。
2023-05-28 22:26:48 +08:00
### reload
#### 只做刷新
重新发送`api`请求,刷新 Chart 时,只配置`componentId`目标组件 ID 即可。
2023-05-28 22:26:48 +08:00
```schema: scope="body"
[
{
"type": "button",
"label": "刷新请求",
"onEvent": {
"click": {
"actions": [
{
"componentId": "chart01",
"actionType": "reload"
}
]
}
}
},
{
"type": "chart",
"id": "chart01",
"api": "/api/mock2/chart/chartData",
"config": {
"xAxis": {
"type": "category",
"data": [
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
]
},
"yAxis": {
"type": "value"
},
"series": [
{
"data": "${line || []}",
"type": "line"
}
]
}
}
]
```
#### 发送数据并刷新
2023-07-14 17:38:42 +08:00
刷新 Chart 组件时,如果配置了`data`,将发送`data`给目标组件,并将该数据合并到目标组件的数据域中(如果配置`"dataMergeMode": "override"`将覆盖目标组件的数据),然后重新请求数据。
```schema: scope="body"
[
{
"type": "button",
"label": "刷新请求",
"onEvent": {
"click": {
"actions": [
{
"componentId": "chart01",
"actionType": "reload",
"data": {
"xAxis": [
"周一",
"周二",
"周三",
"周四",
"周五",
"周六"
]
}
}
]
}
}
},
{
"type": "chart",
"id": "chart01",
"data": {
"xAxis": [
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
]
},
"api": "/api/mock2/chart/chartData",
"config": {
"xAxis": {
"type": "category",
"data": "${xAxis}"
},
"yAxis": {
"type": "value"
},
"series": [
{
"data": "${line || []}",
"type": "line"
}
]
}
}
]
```
2023-05-28 22:26:48 +08:00
### setValue
通过`setValue`更新指定图表的数据。
#### 合并数据
默认`setValue`会将新数据与目标组件数据进行合并。
2023-05-28 22:26:48 +08:00
```schema: scope="body"
[
{
"type": "button",
"label": "更新数据",
"onEvent": {
"click": {
"actions": [
{
"componentId": "chart02",
"actionType": "setValue",
"args": {
"value": {
"line":[98,41,51,2,90,40]
}
2023-05-28 22:26:48 +08:00
}
}
]
}
}
},
{
"type": "chart",
"id": "chart02",
"data": {
"xAxis": [
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
]
},
2023-05-28 22:26:48 +08:00
"api": "/api/mock2/chart/chartData",
"config": {
"xAxis": {
"type": "category",
"data": "${xAxis}"
},
"yAxis": {
"type": "value"
},
"series": [
{
"data": "${line || []}",
"type": "line"
}
]
}
}
]
```
#### 覆盖数据
可以通过`"dataMergeMode": "override"`来覆盖目标组件数据。
```schema: scope="body"
[
{
"type": "button",
"label": "更新数据",
"onEvent": {
"click": {
"actions": [
{
"componentId": "chart02",
"actionType": "setValue",
"args": {
"value": {
"line":[98,41,51,2,90,40]
}
},
"dataMergeMode": "override"
}
]
}
}
},
{
"type": "chart",
"id": "chart02",
"data": {
"xAxis": [
2023-05-28 22:26:48 +08:00
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
]
},
"api": "/api/mock2/chart/chartData",
"config": {
"xAxis": {
"type": "category",
"data": "${xAxis}"
2023-05-28 22:26:48 +08:00
},
"yAxis": {
"type": "value"
},
"series": [
{
"data": "${line || []}",
