Good day, all. I'm having a bit of a puzzling issue here, and maybe someone can point me to my error.
But this is what I get in the Web Viewer:
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?
