I just came across this and thought I’d let you know you can go grab a new improved pasteable JS embed from our any of our reporting views.

That will fix your error!

I’ve had similar experience with SVG::Graph and slightly more recently Gruff. Gruff seemed the better of the two by a wide margin. That said, it requires RMagick which is (a) a PITA and (b) impractical with JRuby.

P.S. Comment preview would be nice. D.S.
