You need to include the excanvas script before Flot. It contains compatibility 
code
to make IE work.

This is documented in the examples and the README. I'm closing this bug now as I
don't think I can do much more.

I just had the same problem, it turned out i didn't include the excanvas script 
correctly (wrong dir to file). Try adding 'alert("Test")' in the top of the 
excanvas 
script, if it is loaded correctly you should get a pop saying "Test". 
I don't hope this message is inappropriate for a bug board, I just thought i 
might help 
others in the same situation.

I had this error message when loading my Google Gadget using IE.  Yes, it has
something to do with problem loading excanvas.js file.  My original code was:

<Content type="html"><![CDATA[
<!--[if IE]><script type="text/javascript" 
src="excanvas.js"></script><![endif]-->
<script src="http://www.google.com/jsapi" type="text/javascript"></script>

As it turns out, there need to be something between <![CDATA[ and the 
conditional
comment <!--[if IE]>... even if it is just a <p> or another <script> line.

So I changed my code to:

<Content type="html"><![CDATA[
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<!--[if IE]><script type="text/javascript" 
src="excanvas.js"></script><![endif]-->

It is working now.

It is still reproducible for me.

README.TXT mentions 
  <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.pack.js"></script><![endif]-->

but there is no excanvas.pack.js, 
but there is excanvas.js and min version

Igor, the README wasn't updated when excanvas.pack.js was renamed to 
excanvas.min.js. That error was fixed some time ago. Just use excanvas.min.js 
as the examples are doing. :)

It was called pack because I used to use the whacky packer until finding out it 
was actually much faster to minify and turn on gzip compression (the jQuery 
maintainer blogged about this).

How do I handle IE < 9 if I do not want (or can not) include excanvas?

I'd like flot to be able to "degrade" gracefully.

Can I test for compatibility?

I still have problem with flot compatibility to IE6/ IE7. As suggested in 
README, the "excanvas.min.js" file was included. But still, there's a pop-up 
warning "'xx' is null or not an object". It's not a major problem though, I 
just am curious about how it comes such warning? Any suggestions? Thanks in 
advance

after solving the first problem, i also had the "'xx' is null or not an object" 
- problem. 
There was a comma too much in the "$.plot(...)"-thingy. Deleted it and now 
everything works fine. Thanks

I still have the first problem but in my case it window.G_vmlCanvasManager is 
UNDEFINED. The excanvas.js is executed at start (I've checked this by 
debugging). I dont use any condition anymore...
<script src="<%= request.getContextPath() %>/js/jqpot/excanvas.js" 
type="text/javascript" charset="utf-8"></script>
