The embedded symbols will be evaluated at run-time, so they will be correct both on the display and if you send this command to a PostScript file, or make a
high-quality raster file with ImageMagick. Here, for example, is how the figure below was created.

   cgPlot, cgDemoData(1), XTitle='Length ($\mu$M)', YTitle='Distance ($\Angstrom$$\up2$)', $
       Output='embedsymbols_1.png', Aspect = 0.66

Embedded symbols are rendered correctly on the display and in PostScript and in
high-quality raster files.

There is no particular limit to how many characters can be included in superscripts and subscripts. The following embedded symbols can be used.

$\upTEXT$ — Raise the text in TEXT to superscript level and reduce character size by 62%.
$\extTEXT$ — Raise the text in TEXT to superscript level and reduce character size by 44%.
$\downTEXT$ — Lower the text in TEXT to subscript level and reduce character size by 62%.
$\subTEXT$ — Lower the text in TEXT to subscript level and reduce character size by 44%.

Here is a contrived example.

   cgPlot, cgDemoData(1), Charsize=2.0, $
       XTitle='Distance ($\angstrom$$\up2$)', $
       YTitle='H$\subSubscript$ and B$\expSuperscript$'

You see the results here.
