javascript - Amcharts - 在同一页面上的 Amchart 3 中创建 2 个图表实例

转载作者：行者123 更新时间：2023-11-30 14:58:04

我正在尝试在同一页面上创建 2 个 Amchart 实例。在这里，我手动放置数据。但是我使用 dataloader 从 php 文件加载数据，使用 mysql 输出 json。为此，我将使用 2 个不同的 php 文件输出 json。

我用不同的 id 创建了一个额外的 div。并在 javascript 中创建了另一个图表实例并更改了其中的图表 ID。问题是它仍在创建单个图表。我做错了什么？

这是我的代码片段-

<div id="chartdiv"></div>
<h2>Second Chart</h2>
<div id="chart1div"></div>

最佳答案

将 CSS 中的 #chardiv 更改为 .chartdiv。然后将该类添加到 DivElements，例如:

<div id="chartdiv" class="chartdiv"></div>
<h2>Second Chart</h2>
<div id="chart1div" class="chartdiv"></div>
