我想显示一个图表使用chart.js在Angular 。在第一次我尝试实现一个例子采取了在网上,我没有问题编译。这是代码在我的.ts:
import { Component, OnInit } from '@angular/core';
import { Chart } from "chart.js";
@Component({
...
})
export class MyChartComponent implements OnInit {
constructor(){
}
ngOnInit(): void {
new Chart("myChart", {
type: 'bar',
data: {
labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});
}
}
在我的.html中,我有:
<div id="divChart">
<canvas id="myChart"></canvas>
</div>
但是当我开始发球时,我有这个错误:
