Google visualization not working with local file

问题

I'm working with a treemap, but the scale is coming out black. (related question: Google TreeMap fill value set to _ABSTRACT_RENDERER_ID_1). After reading that I was able to track down the problem to the code that google generates. It looks like the definitions are being declared correctly, but then the url to them looks like maybe doesn't work with local files. Perhaps because I'm working with a local file, see below: url(file:///D:/... )

<defs>
<linearGradient gradientUnits="userSpaceOnUse" ...  id="_ABSTRACT_RENDERER_ID_2">
...
<linearGradient gradientUnits="userSpaceOnUse" ... id="_ABSTRACT_RENDERER_ID_3">
...
</defs>

...

<rect fill="url(file:///D:/.../Original.html#_ABSTRACT_RENDERER_ID_2)" ... ></rect>
<rect fill="url(file:///D:/.../Original.html#_ABSTRACT_RENDERER_ID_3)" ... ></rect></g>

I've simplified the code by replacing irrelevant bits with .... I hope that doesn't confuse anyone.

Is this a problem due to not running from a server? (edit: I set up IIS on my machine. It's confirmed, the scale renders correctly)

From what I have seen from online examples is that there is no need to specify the file.

<rect fill="url(#_ABSTRACT_RENDERER_ID_2)" ... ></rect>
<rect fill="url(#_ABSTRACT_RENDERER_ID_3)" ... ></rect></g>

Is it possible to get this working from my local file system?

回答1:

Parentheses and single quotes are not permitted in the path. I.e, ( ) and '.

The other acceptable path characters do not cause a problem for rendering the treemap scale: {}`` &-,.[]^%$#@!; (Those are back quotes in there)
