Using quotes inside sageplot environment in SageTeX

Question

Here's the question: how do I get the following to work in SageTeX? The quotes always lead to an error.

\sageplot{plot(cos(x),(x,0,pi),label='$\cos(x)$')}

Double quotes, escaping them, ... nothing seems to work. Thanks!

Accepted Answer

I'll post just so people don't have to jump to Tex Stack Exchange. Here's a method that will give you some freedom on your text label:

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\pagestyle{empty}
\begin{sagesilent}
G=Graphics()
H=Graphics()
var('x')
G+=plot(cos(x),(x,0,pi))
H+= text("$\cos(x)$", (3, 1), fontsize=16, color='black')
\end{sagesilent}
\[ \sageplot{G+H}\] 
\end{document}

See the Stack Exchange post for a more complete answer. And yes, the code above could be cleaned up (simplified) as well.

As I pointed out on SX, this works, and you could probably just get rid of everything except the last two lines, where you'd just do G = ... etc. There must be something wrong with the sageplot parser, I'm going to email the SageTeX author about this. He owes me a few anyway ;-)
