# Latest Update
* 2024.12.02: v19.0.0
+ Feat: Upgrade to angular 19
+ **BREAKING CHANGES**:
+ According to [issue #443](https://github.com/xieziyu/ngx-echarts/issues/437), we cannot import from `echarts/index.js` using Angular 19. Therefore, we need to perform a custom build and import everything required from `echarts/core`, `echarts/charts`, `echarts/components`, or other specific entry points.
+ `provideEcharts` is REMOVED.
[CHANGELOG.md](./CHANGELOG.md)
# Installation
- Since v5.0
```bash
# if you use npm
npm install echarts -S
npm install ngx-echarts -S
# or if you use yarn
yarn add echarts
yarn add ngx-echarts
```
- If you need ECharts GL support, please install it first:
```bash
npm install echarts-gl -S
# or
yarn add echarts-gl
```
- Import other extensions such as themes or `echarts-gl` in your `main.ts`: [ECharts Extensions](#echarts-extensions)
## Upgrade from v4.x
1. import `echarts` and provide it in `NgxEchartsModule.forRoot({ echarts })`.
2. `NgxEchartsCoreModule` is removed.
# Usage
Please refer to the [demo](https://xieziyu.github.io/ngx-echarts) page.
## Standalone
import `NgxEchartsDirective` and `provideEchartsCore`. Or you can use `provideEchartsCore` to do treeshaking custom build.
```typescript
import { NgxEchartsDirective, provideEchartsCore } from 'ngx-echarts';
// import echarts core
import * as echarts from 'echarts/core';
// import necessary echarts components
import { BarChart } from 'echarts/charts';
import { GridComponent } from 'echarts/components';
import { CanvasRenderer } from 'echarts/renderers';
echarts.use([BarChart, GridComponent, CanvasRenderer]);
@Component({
selector: 'app-root',
standalone: true,
imports: [CommonModule, NgxEchartsDirective],
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss'],
providers: [
provideEchartsCore({ echarts }),
]
})
export class AppComponent {}
```
## NgModule
import `NgxEchartsModule`:
```typescript
import { NgxEchartsModule } from 'ngx-echarts';
// import echarts core
import * as echarts from 'echarts/core';
// import necessary echarts components
import { BarChart } from 'echarts/charts';
import { GridComponent } from 'echarts/components';
import { CanvasRenderer } from 'echarts/renderers';
echarts.use([BarChart, GridComponent, CanvasRenderer]);
@NgModule({
imports: [
NgxEchartsModule.forRoot({ echarts }),
],
})
export class AppModule {}
```
## Directive
use `echarts` directive in a div which has **pre-defined height**. (From v2.0, it has default height: 400px)
- html:
```html
```
- css:
```css
.demo-chart {
height: 400px;
}
```
- component:
```typescript
import { EChartsCoreOption } from 'echarts/core';
// ...
chartOption: EChartsCoreOption = {
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',
},
],
};
```
# API
### Directive
`echarts` directive support following input properties:
| Input | Type | Default | Description |
| --------------- | ------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `[options]` | object | null | The same as the options on the official demo site. |
| `[merge]` | object | null | Used to update a part of the `options`, especially helpful when you need to update the chart data. In fact, the value of `merge` will be used in `echartsInstance.setOption()` with `notMerge = false`. Refer to [ECharts documentation](https://echarts.apache.org/en/api.html#echartsInstance.setOption) for details. |
| `[loading]` | boolean | false | Used to toggle the echarts loading animation when your data is not ready. |
| `[autoResize]` | boolean | true | If set to `true`, the chart will be automatically resized when the window's width is changed. |
| `[initOpts]` | object | null | The value of `[initOpts]` will be used in `echarts.init()`. It may contain `devicePixelRatio`, `renderer`, `width` or `height` properties. Refer to [ECharts documentation](https://echarts.apache.org/en/api.html#echarts.init) for details. |
| `[theme]` | string | null | Used it to initialize echarts with theme. The theme file must also be imported in `main.ts`. |
| `[loadingOpts]` | object | null | Input an object to customize the loading style. Refer to [ECharts documentation](https://echarts.apache.org/en/api.html#echartsInstance.showLoading) for details. |
By default, `loadingOpts` is:
```javascript
{
text: 'loading',
color: '#c23531',
textColor: '#000',
maskColor: 'rgba(255, 255, 255, 0.8)',
zlevel: 0
}
```
### ECharts API
If you need to access parts of the ECharts API such as `echarts.graphic`, please import it from echarts. For example:
```typescript
import { graphic } from 'echarts/core';
new graphic.LinearGradient(/* ... */);
```
### ECharts Instance
`echartsInstance` is exposed (since v1.1.6) in the `(chartInit)` event, enabling you to directly call functions like: `resize()`, `showLoading()`, etc. For example:
- html:
```html
```
- component:
```typescript
onChartInit(ec) {
this.echartsInstance = ec;
}
resizeChart() {
if (this.echartsInstance) {
this.echartsInstance.resize();
}
}
```
### ECharts Extensions
Import echarts theme files or other extension files after you have imported `echarts` core. For example:
```typescript
import * as echarts from 'echarts/core';
/** echarts extensions: */
import { Bar3DChart } from 'echarts-gl/charts';
import { Grid3DComponent } from 'echarts-gl/components';
import 'echarts/theme/macarons.js';
import 'echarts/dist/extension/bmap.min.js';
```
### Service
`NgxEchartsService` has been obsolete since v4.0
# Events
As ECharts supports the `'click'`, `'dblclick'`, `'mousedown'`, `'mouseup'`, `'mouseover'`, `'mouseout'`, and `'globalout'` mouse events, our `ngx-echarts` directive also supports the same mouse events but with an additional `chart` prefix. For example:
- html:
```html
```
- The '\$event' is same with the 'params' that ECharts dispatches.
It supports following event outputs:
| @Output | Event |
| ------------------------------ | -------------------------------------- |
| chartInit | Emitted when the chart is initialized |
| chartClick | echarts event: `'click'` |
| chartDblClick | echarts event: `'dblclick'` |

| chartGraphRoam | echarts event: `'graphroam'` |
| chartGeoRoam | echarts event: `'georoam'` |
| chartTreeRoam | echarts event: `'treeroam'` |
| chartTimelineChanged | echarts event: `'timelinechanged'` |

You can refer to the ECharts tutorial: [Events and Actions in ECharts](https://echarts.apache.org/en/tutorial.html#Events%20and%20Actions%20in%20ECharts) for more details of the event params. You can also refer to the [demo](https://xieziyu.github.io/#/ngx-echarts/demo) page for a detailed example.
# Custom Build
## Treeshaking Custom Build
> Since version 5.0.1 ECharts supports [Treeshaking with NPM](https://echarts.apache.org/en/tutorial.html#Use%20ECharts%20with%20bundler%20and%20NPM).
The `app.modules.ts` should look like this:
```typescript
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { NgxEchartsDirective, provideEchartsCore } from 'ngx-echarts';
import { AppComponent } from './app.component';
// Import the echarts core module, which provides the necessary interfaces for using echarts.
import * as echarts from 'echarts/core';
// Import bar charts, all suffixed with Chart
import { BarChart } from 'echarts/charts';
// Import the tooltip, title, rectangular coordinate system, dataset and transform components
import {
TitleComponent,
TooltipComponent,
GridComponent,
DatasetComponent,
TransformComponent
} from 'echarts/components';
// Features like Universal Transition and Label Layout
import { LabelLayout, UniversalTransition } from 'echarts/features';
// Import the Canvas renderer
// Note that including the CanvasRenderer or SVGRenderer is a required step
import { CanvasRenderer } from 'echarts/renderers';
// Import the theme
import 'echarts/theme/macarons.js';
// Register the required components
echarts.use([
BarChart,
TitleComponent,
TooltipComponent,
GridComponent,
DatasetComponent,
TransformComponent,
LabelLayout,
UniversalTransition,
CanvasRenderer
]);
@NgModule({
declarations: [AppComponent],
imports: [
BrowserModule,
HttpClientModule,
// import standalone directive:
NgxEchartsDirective,
],
providers: [{
// Provide custom builded ECharts core:
provideEchartsCore({ echarts })
}],
bootstrap: [AppComponent],
})
export class AppModule {}
```
## Legacy Custom Build
> Please refer to [ECharts Documentation](https://echarts.apache.org/en/tutorial.html#Create%20Custom%20Build%20of%20ECharts) for more details.
If you want to produce a custom build of ECharts, prepare a file like `custom-echarts.ts`:
```ts
// custom-echarts.ts
export * from 'echarts/src/echarts';
import 'echarts/src/chart/line';
import 'echarts/src/chart/bar';
// component examples:
import 'echarts/src/component/tooltip';
import 'echarts/src/component/title';
import 'echarts/src/component/toolbox';
```
And then inject it in your `NgxEchartsModule`:
```ts
import { NgxEchartsModule } from 'ngx-echarts';
import * as echarts from './custom-echarts';
@NgModule({
imports: [
NgxEchartsModule.forRoot({
echarts,
}),
],
})
export class AppModule {}
```
And if you want to use the global `echarts` object, please import it from `lib` or `src` instead:
```ts
import * as echarts from 'echarts/lib/echarts';
```
If you need to import theme files, remember to change the `'echarts'` path to `'echarts/lib/echarts'`, for example:
```ts
// ... part of echarts/theme/dark.js:
function (root, factory) {
if (typeof define === 'function' && define.amd) {
// AMD. Register as an anonymous module.
define(['exports', 'echarts/lib/echarts'], factory);
} else if (typeof exports === 'object' && typeof exports.nodeName !== 'string') {
// CommonJS
factory(exports, require('echarts/lib/echarts'));
} else {
// Browser globals
factory({}, root.echarts);
}
}
```
# Custom Locale
You can change the chart locale registering a built-in locale (located in `node_modules/echarts/lib/i18n/`) or a custom locale object. To register a locale, you will need to change the module that echart is being imported (usually `app.module.ts`).
```ts
import {NgxEchartsModule} from "ngx-echarts";
import * as echarts from 'echarts/core';
import langCZ from 'echarts/lib/i18n/langCZ';
echarts.registerLocale("CZ", langCZ)
@NgModule({
imports: [NgxEchartsModule.forRoot({echarts})],
declarations: [],
providers: [],
bootstrap: [AppComponent]
})
```
and in your HTML file use:
```html
```
