Hi Jeff, I don't have the problem with the overlapping m. The impact of the presence of the color function seems to be that the font is replaced by a bitmapped version or so. Without the color function the font is smoothed and anti-aliased, with the color function it's not. Looks like a clear bug to me. You might consider reporting this to support at wolfram.com. I don't seem to need the [#]& behind the colorfunction. It's a redundant notation anyways. I used a slightly modified version of your code: Plot[x, {x, 1, 1000}, ColorFunction -> (ColorData["VisibleSpectrum"]), ColorFunctionScaling -> False, Filling -> Axis, Frame -> True, FrameLabel -> "Wavelength (\[Mu]m)"] The y=x in the Plot argument was probably erroneous.

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?
