Question

我为这个问题尝试了不同的解决方案，例如：

使用修改后的html5shiv。 html5shiv脚本添加了将HTML5标记添加到旧版Internet Explorer中的功能。

<!--[if lt IE 9]>
    <script src="dist/html5shiv.js"></script>
<![endif]-->

使用excanvas为
提供后备

    <!--[if lte IE 8]>
        <script type="text/javascript" src="/Scripts/excanvas.min.js"></script>
    <![endif]-->

没有任何帮助。收到错误：

Canvas不可用。如果你正在使用带有后备的IE Excanvas，那么你的条件包含有错，或者页面没有DOCTYPE，并且在Quirks模式下呈现。

其他一些解决方案？

上面包含flot.js之前的所有脚本。

更改DOCTYPE也无济于事。

Answer 1

前几天我遇到了这个问题，this blog post用这些说明救了我：

使用Flot存储库中包含的excanvas.js（或更小的excanvas.min.js）。这个与我认为的不同，并包含必要的修改以使其起作用



在包含Flot JavaScript文件之前包含excanvas JavaScript文件。

确保工具 - >开发人员工具 - >浏览器模式也设置为“IE8”！

Flot Chart：在IE 8中不起作用
