我正在尝试使用ng2-charts并遇到一个错误,指出我使用的元素不正确.
我在这个网站上尝试了几个答案,但没有运气:
NG2-Charts无法绑定到'数据集',因为它不是'canvas'的已知属性
ng2-charts - 无法绑定到"数据集",因为它不是"基础图表"的已知属性
这是我的代码:
import { Component } from "@angular/core";
@Component({
moduleId: module.id,
templateUrl: "four-item-horse-shoe-graph.component.html",
styleUrls: ["four-item-horse-shoe-graph.component.css"],
selector: "four-item-horse-shoe"
})
export class FourItemHorseShoeGraphComponent {
// Doughnut
public doughnutChartLabels: string[] = ["Download Sales", "In-Store
Sales", "Mail-Order Sales"];
public doughnutChartData: number[] = [350, 450, 100];
public doughnutChartType: string = "doughnut";
// events
public chartClicked(e: any): void {
console.log(e);
}
public chartHovered(e: any): void {
console.log(e);
}
}
和HTML:
<div style="display: block">
<canvas baseChart
[data]="doughnutChartData"
[labels]="doughnutChartLabels"
[chartType]="doughnutChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)">
</canvas> …由于某种原因,我的代码的页脚部分的CSS不起作用.我希望页脚具有绿色背景,并使其位于正常容器之外.css正在为其他东西工作.有谁之前经历过这个吗？
这是我的代码:

我得到的当前错误是:
错误(75,1):PLS-00103:当遇到以下情况之一时遇到符号"DROP":(如果循环模式为空,则返回异常退出,如果循环mod为空,则pragma raise返回选择更新,同时使用<< continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge
我想我还有更多.有人能帮助我弄清楚我做错了什么吗？
这是我有的:
