这段代码的输出是：！在此处输入图像描述

然后我尝试编辑上面的代码以添加下载按钮以将这些图表导出为 imges/PDF 格式..但是这个下载按钮仍然没有显示给我。需要的下载按钮是：在此处输入图像描述

然后我需要像这样得到最终输出：在此处输入图像描述

我想将此下载按钮添加到我的图表中...我该怎么做???请帮助我...

图表上的这个下载按钮仅在 JavaScript 图表中可用，并且您可能正在渲染 Flash 图表。

有很多方法：

  1. 传递 JavaScript 图表别名而不是 SWF 名称作为 的第一个参数renderChart：

    renderChart("Column3D" ...

  2. renderChart您可以在函数调用之前在 PHP 中添加此代码：

     FC_SetRenderer( "javascript" );

  3. 在页面顶部添加一小行 JavaScript（包含后FusionCharts.js）

    FusionCharts.setCurrentRenderer('javascript');

此外，您可以右键单击 Flash 图表以获取菜单。
