如何在 chartjs 中显示 y 轴上的条形图
how to show bar graph on y axis in charjs
我正在使用使用 chartjs 的 ng2-charts。 Angular 版本为 8.2.14。我必须显示条形图,但它们必须从 Y 轴而不是 X 轴开始。意味着图表应该从 y 轴增长。有什么方法可以实现?
您必须在配置选项中将图表的 type
定义为 horizontalBar
:
var myBarChart = new Chart(ctx, {
type: 'horizontalBar',
data: data,
options: options
});
或 ng2-charts 的 TypeScript:
public barChartType: ChartType = 'horizontalBar';
谨记
The configuration options for the horizontal bar chart are the same as for the bar chart.
However, any options specified on the x axis in a bar chart, are applied to the y axis in a horizontal bar chart.
这是 Stackblitz 上的一个例子:
https://stackblitz.com/edit/ng2-charts-bar-template-vqunbc
export class AppComponent {
public barChartOptions: ChartOptions = {
responsive: true,
};
public barChartLabels: Label[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
public barChartType: ChartType = 'horizontalBar';
public barChartLegend = true;
public barChartPlugins = [];
public barChartData: ChartDataSets[] = [
{ data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
{ data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
];
constructor() { }
ngOnInit() {
}
}
