在数据可视化领域，ECharts 是一款非常流行的 JavaScript 库，它可以帮助开发者轻松创建交互式图表。堆积图是 ECharts 中的一种图表类型，它能够有效地展示数据的趋势和分布。本文将带你一步步学会如何使用 ECharts 创建堆积图，让你轻松地展示数据之美。
堆积图的基本概念
堆积图是一种组合图表，它可以将多个数据系列堆叠在一起，形成一个新的数据系列。这种图表类型常用于展示多个数据系列随时间变化的趋势，或者展示多个部分组成整体的情况。
环境准备
在使用 ECharts 创建堆积图之前，你需要确保以下环境：
- HTML 文件：创建一个 HTML 文件，用于引入 ECharts 库。
- JavaScript 库：ECharts 的最新版本可以从其官方网站下载。
以下是一个简单的 HTML 文件示例：
”`html <!DOCTYPE html>
