[pstricks] \sqrt in axislabel

[Caroline Leppert]

Hi,

I tried to use the \sqrt command in an axislabel for the psgraph 
environment but got an error message, see example.

Any other math command seems to work fine. I've already checked 
something like yAxisLabel=$\int y_{y}^2$ without problems.

Any ideas?

Best regards,
Caroline
