RGraph JavaScript charting in a WebViewer

Good day, all. I'm having a bit of a puzzling issue here, and maybe someone can point me to my error.

 

It's the first time I've tried to create a JavaScript chart for use in a runtime. (Long story; don't ask.) I connected with the RGraph.net library based on a post from logicurio. So I set it up to contain the libraries in-line (to avoid needing web access), and tried the sample chart that comes with the documentation. This is what I get in the browser (IE, Chrome, and FireFox):

But this is what I get in the Web Viewer:

 

chartFail.png

 

Okay, so, is there something special about the canvas tag that the Web Viewer doesn't like? I copied and pasted the exact output of the Web Viewer calculation into an HTML document, and it works fine, so I know it's not purely the code. The only wrinkle is that I need to use the data URL method in the Web Viewer to get this much to show up. (If I don't, I get raw code.)

 

Any ideas what I might be doing wrong here?

 

TIA

 

Mike
