The space disappears if you remove the ColorFunction gradient from the plot parameters. Also, if you change \[Mu] to a standard character like m, the formatting looks perfectly acceptable. To be honest, I don't really understand the reason for the [#] & following the ColorData tag, but the gradient doesn't seem to work properly without it. Is my syntax correct? I got it to render ok (V7.0.1 on OS X 10.5.7) by adding an invisible space: (\[Mu]\[VeryThinSpace]m) ...but I'm not sure why the problem you've reported occured. ColorFunction -> "VisibleSpectrum" is all you need. Mike
