我使用的是AmCharts，除了导出以外，一切都正常。为什么AmCharts导出颜色变为黑色和白色？
我使用下面库AmCharts：
<link href="https://www.amcharts.com/lib/3/plugins/export/export.css" media="all" rel="stylesheet" type="text/css" />
<script src="~/Content/amcharts_3.20.9.free/amcharts/amcharts.js"></script>
<script src="~/Content/amcharts_3.20.9.free/amcharts/serial.js"></script>
<script src="~/Content/amcharts_3.20.9.free/amcharts/themes/light.js"></script>
<script src="https://www.amcharts.com/lib/3/plugins/export/export.js"></script>
和内部AmCharts.makeChart("chartdiv2", {我使用：
"export": {
"enabled": true
}`
我的图表是默认丰富多彩这样的：
但是我下载到PDF后， PNG，JPG等，或单击Annotate...菜单选项图表转为黑白（灰度）这样的形象：
Here is video of this issue reproduced。

<div id="chartdiv2"></div>而问题的JSFiddle。
我已经在Google的Chrome和Mozilla的Firefox中测试了这种行为请指导我如何修改此问题以使其更易于理解？我搜索了很多，但在网上找不到类似的问题。我真的很感激，如果amcharts.com支持也参与帮助。
如果可能请在https://jsfiddle.net/或类似的服务上提供示例。 –
我的代码是写在ASP.Net MVC和一些剃须刀是包括可以jsfiddle会理解我的代码？ –
我从浏览器中生成的代码制作一个JSFiddle我会回来一段时间的代码，请稍等，谢谢 –
