The problem is that excanvas does not have support for ImageData functions, so you cannot get the image date like you can do with native canvas.
问题是，excanvas不支持ImageData函数，因此不能像使用本机画布那样获得图像日期。
The only polyfill for canvas, that i know, which supports this is FlashCanvas Pro. But i neither can tell you if it works with jqplot nor can i tell you if it performs well, because i have never used it.
我知道，画布的唯一的填充工具是FlashCanvas Pro。但我也不能告诉你它是否与jqplot合作，我也不能告诉你它是否运行良好，因为我从未使用过它。
EDIT
Based on your edited question:
With this: var imgElem = $('<img/>').attr('src',imgData); you set a data url.
But data url are not support for IE 7 and older, and for IE 8 the data url is limited to 32 KB which would be most likely be a problem if you create a larger image with jqplot.
根据你编辑的问题编辑:var imgElem = $('
').attr('src'，imgData);设置一个数据url。但是，数据url不支持IE 7和更老的数据，对于IE 8，数据url被限制为32 KB，如果用jqplot创建一个更大的图像，这很可能是一个问题。
EDIT Based on the comment, that the client should be able to download the image:
If - as i said i don't know - the Pro version of FlashCanvas can create a data url reliable. You could think over doing a POST (this is required because GET request are also limited in size) of that data url to your server. On the server you can create an image out of that data, store it and submit the url to that temporary image as a response of the post. Then you could use this url for the image. This is for sure not an optimal solution but at least a workaround until you find something that works better.
根据评论编辑，客户端应该能够下载图片:如果-正如我说的我不知道- - -专业版的FlashCanvas可以创建一个可靠的数据url。您可以考虑做一个POST(这是必需的，因为GET请求的大小也是有限的)到服务器的数据url。在服务器上，您可以从该数据创建一个图像，存储它并将url提交给该临时映像作为post的响应。然后你可以使用这个url作为图像。这肯定不是一个最优的解决方案，但至少是一个解决方案，直到你找到更好的方法。
For posting the data you could use jquery.post and return a json formatted response with the url to the temporary image.
为了发布数据，您可以使用jquery。post并将一个json格式的响应返回给临时图像。
With modernizr.com you could check if the browser supports dataurl and only do this fallback if it does not support it. For IE 8 you probably need to do further checks.
使用现代化的网站，你可以检查浏览器是否支持dataurl，如果它不支持dataurl，就只做这个回退。对于IE 8，你可能需要做进一步的检查。

In the case of IE, each IE runs with separate mind,
在IE的情况下，每个IE都是独立运行的，
even jQuery and Plugins do not work with IE sometimes, this seems same..
即使是jQuery和插件也不能与IE一起工作。
the Basic problem is support provided by IE for JavaScript is not consistent throughout versions.
基本问题是IE为JavaScript提供的支持在整个版本中不一致。
Few Minor things that you need to change.
你需要改变的小事情很少。
you already have specified <!DOCTYPE HTML>
您已经指定了
further you need to specify meta to define its type.
您还需要指定meta来定义它的类型。
that guides IE to identify the content type.. (dumb IE)
引导IE识别内容类型。(愚蠢的IE)
<meta http-equiv="X-UA-Compatible" contant="IE=edge" />
Please define all meta after this Meta TAG.
请在此元标签后定义所有元。
and after that here come this code that you have to define before you start defining scripts.
在此之后，您必须在开始定义脚本之前定义这些代码。
<!--[if lt IE 9]>
<script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE9.js"></script>
<![endif]-->
This makes thing moreover under control.
这使得事情变得更加可控。
Please change this and see the difference.
请改变这一点，看看区别。
Update: If there is something related to plotting specific,

Edit : DataURL in IE 8
编辑:ie8中的DataURL。
Please refer old post how this will work or alternate to make it work. although the way is not easy but a work around with help of MHTML(Mime based html), CSS and the constraint is 32 KB of size. Please watch out if some other work around is there..
请参考以前的文章，这将如何工作或替代使它工作。虽然这种方法并不容易，但是在MHTML(基于Mime的html)的帮助下，CSS和约束的大小是32kb。如果附近有其他工作，请留神。
And below IE8 there is not support for data URI.
在IE8之下，不支持数据URI。
Edit: New Link found

There is a trick using CSS file and calling it as MHTML Mime type. Link to Page
有一个使用CSS文件的技巧，并将其称为MHTML Mime类型。链接页面
I think this will help,(Limitations will be same for size constraint.
我认为这将会有所帮助(限制对于大小限制也是一样的)。
If any concern please reply

The problem is that excanvas does not have support for ImageData functions, so you cannot get the image date like you can do with native canvas.
问题是，excanvas不支持ImageData函数，因此不能像使用本机画布那样获得图像日期。
The only polyfill for canvas, that i know, which supports this is FlashCanvas Pro. But i neither can tell you if it works with jqplot nor can i tell you if it performs well, because i have never used it.
我知道，画布的唯一的填充工具是FlashCanvas Pro。但我也不能告诉你它是否与jqplot合作，我也不能告诉你它是否运行良好，因为我从未使用过它。
EDIT
Based on your edited question:
With this: var imgElem = $('<img/>').attr('src',imgData); you set a data url.
But data url are not support for IE 7 and older, and for IE 8 the data url is limited to 32 KB which would be most likely be a problem if you create a larger image with jqplot.
根据你编辑的问题编辑:var imgElem = $('').attr('src'，imgData);设置一个数据url。但是，数据url不支持IE 7和更老的数据，对于IE 8，数据url被限制为32 KB，如果用jqplot创建一个更大的图像，这很可能是一个问题。
EDIT Based on the comment, that the client should be able to download the image:
If - as i said i don't know - the Pro version of FlashCanvas can create a data url reliable. You could think over doing a POST (this is required because GET request are also limited in size) of that data url to your server. On the server you can create an image out of that data, store it and submit the url to that temporary image as a response of the post. Then you could use this url for the image. This is for sure not an optimal solution but at least a workaround until you find something that works better.
根据评论编辑，客户端应该能够下载图片:如果-正如我说的我不知道- - -专业版的FlashCanvas可以创建一个可靠的数据url。您可以考虑做一个POST(这是必需的，因为GET请求的大小也是有限的)到服务器的数据url。在服务器上，您可以从该数据创建一个图像，存储它并将url提交给该临时映像作为post的响应。然后你可以使用这个url作为图像。这肯定不是一个最优的解决方案，但至少是一个解决方案，直到你找到更好的方法。
For posting the data you could use jquery.post and return a json formatted response with the url to the temporary image.
为了发布数据，您可以使用jquery。post并将一个json格式的响应返回给临时图像。
With modernizr.com you could check if the browser supports dataurl and only do this fallback if it does not support it. For IE 8 you probably need to do further checks.
使用现代化的网站，你可以检查浏览器是否支持dataurl，如果它不支持dataurl，就只做这个回退。对于IE 8，你可能需要做进一步的检查。

In the case of IE, each IE runs with separate mind,
在IE的情况下，每个IE都是独立运行的，
even jQuery and Plugins do not work with IE sometimes, this seems same..
即使是jQuery和插件也不能与IE一起工作。
the Basic problem is support provided by IE for JavaScript is not consistent throughout versions.
基本问题是IE为JavaScript提供的支持在整个版本中不一致。
Few Minor things that you need to change.
你需要改变的小事情很少。
you already have specified <!DOCTYPE HTML>
您已经指定了
further you need to specify meta to define its type.
您还需要指定meta来定义它的类型。
that guides IE to identify the content type.. (dumb IE)
引导IE识别内容类型。(愚蠢的IE)
<meta http-equiv="X-UA-Compatible" contant="IE=edge" />
Please define all meta after this Meta TAG.
请在此元标签后定义所有元。
and after that here come this code that you have to define before you start defining scripts.
在此之后，您必须在开始定义脚本之前定义这些代码。
<!--[if lt IE 9]>
<script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE9.js"></script>
<![endif]-->
This makes thing moreover under control.
这使得事情变得更加可控。
Please change this and see the difference.
请改变这一点，看看区别。

Edit : DataURL in IE 8
编辑:ie8中的DataURL。
Please refer old post how this will work or alternate to make it work. although the way is not easy but a work around with help of MHTML(Mime based html), CSS and the constraint is 32 KB of size. Please watch out if some other work around is there..
请参考以前的文章，这将如何工作或替代使它工作。虽然这种方法并不容易，但是在MHTML(基于Mime的html)的帮助下，CSS和约束的大小是32kb。如果附近有其他工作，请留神。
And below IE8 there is not support for data URI.
在IE8之下，不支持数据URI。
Edit: New Link found
编辑:新链接
There is a trick using CSS file and calling it as MHTML Mime type. Link to Page
有一个使用CSS文件的技巧，并将其称为MHTML Mime类型。链接页面
I think this will help,(Limitations will be same for size constraint.
我认为这将会有所帮助(限制对于大小限制也是一样的)。
If any concern please reply
