界面组件库Kendo UI for Angular入门指南教程：图表 - 迷你图

迷你图是一个没有轴、坐标、图例、标题或其他图表特定元素的小图表。

一般来说，迷你图是简单的、字大小的图形，可以嵌入表格、标题或文本块中。其图形表示的概念是由 Edward Tufte 开发的。 Kendo UI Sparkline 是 Kendo UI Chart 的一个版本，专为此特定应用程序量身定制。虽然标准的 Kendo UI 图表组件的操作类似于块元素（由于其呈现在 div 元素中来允许轻松嵌入文本），但迷你图的操作类似于内联元素，因为它呈现在 span 元素中。

虽然迷你图通常是折线图，但它们也可以呈现为以下图表类型：

线型（默认）
条形图（数据条形图）
柱型
区域
饼图
Bullet

以下示例演示了迷你图的实际应用。

app.component.ts

import { Component } from '@angular/core';

@Component({
selector: 'my-app',
template: `
<p>
A sparkline is a very small chart
<kendo-sparkline [data]="data">
</kendo-sparkline>
, drawn without axes, coordinates or other supportive elements.
</p>
<p>
While sparklines are typically Line Charts
<kendo-sparkline [data]="data">
</kendo-sparkline>
, they can also be rendered as:
<p>
<ul>
<li>
Bar/Column Chart
<kendo-sparkline [data]="data" type="column">
</kendo-sparkline>
</li>
<li>
Area Chart
<kendo-sparkline [data]="data" type="area">
</kendo-sparkline>
</li>
<li>
Pie Chart
<kendo-sparkline [data]="pieData" type="pie">
</kendo-sparkline>
</li>
<li>
Bullet Chart
<kendo-sparkline [data]="bulletData" type="bullet" [valueAxis]="bulletValueAxis">
</kendo-sparkline>
</li>
</ul>
