我正在使用以下版本:
- Angular :14.0.6
- 类型脚本:4.7.4
- Chart.js:^3.8.2
- chartjs插件注解:^1.4.0版本
- 图表插件数据标签:^2.0.0版本
- ng 2-图表:^4.0.0
我尝试用虚拟数据创建一个简单的演示Doughnat图表。问题是,无论我尝试什么,这些值都不会显示在图表上。我用that作为例子帮助自己,但我发现新版本的这种方法不起作用。以下是我迄今为止尝试的方法。
我的应用程序.模块.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HeaderComponent } from './header/header.component';
import { FoodManagementModule } from './food-management/food-management.module';
import { NgChartsModule } from 'ng2-charts';
@NgModule({
declarations: [
AppComponent,
HeaderComponent,
],
imports: [
BrowserModule,
AppRoutingModule,
HttpClientModule,
FoodManagementModule,
NgChartsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
我的模板如下所示:
<div class="container">
<div class="row">
<div class="col-sm-6">
<canvas
baseChart
[datasets]="doughnutChartData"
[labels]="doughnutChartLabels"
[options]="doughnutChartOptions"
[plugins]="doughnutChartPlugins"
[legend]="doughnutChartLegend"
[type]="doughnutChartType"
>
</canvas>
</div>
</div>
</div>
在TS文件中,我导入了pluginDataLabels以及其他类型,如下所示:
import {
ChartConfiguration,
ChartDataset,
ChartOptions,
ChartType,
} from "chart.js";
import * as pluginDataLabels from "chartjs-plugin-datalabels";
"然后我试着这样“
public doughnutChartOptions: ChartConfiguration<'doughnut'>['options'] = {
responsive: true,
plugins: {
datalabels: {
display: true,
anchor: 'center',
align: 'center',
font: {
size: 20,
},
color: "#000000"
},
tooltip: {
enabled: true,
},
title: {
display: true,
text: 'Macros'
},
legend: {
display: true,
},
},
};
// public doughnutChartOptions: ChartOptions = {
// responsive: true,
// plugins: {
// datalabels: {
// color: "#36A2EB",
// display: true,
// anchor: "end",
// align: "end",
// font: {
// size: 20,
// },
// },
// },
public doughnutChartLabels: string[] = ["Proteins", "Carbohydrates", "Fats"];
public doughnutChartType: ChartType = "doughnut";
public doughnutChartLegend: boolean = true;
public doughnutChartPlugins = [pluginDataLabels];
public doughnutChartData: ChartDataset[] = [
{
label: "Example",
data: [33, 44, 55],
datalabels: {
color: "#36A2EB",
display: true,
},
},
];
constructor() {}
ngOnInit(): void { }
但似乎没有什么工作..当我使用旧版本,并按照上面的例子,所有的工作,但我想这样做与较新的版本..任何建议,我做错了什么?
