Well, you could build the string as ['1' char(215) '10^{-4}'] but if really want the extreme of actually doing so I'd recommend you use the \times Tex character sequence. As noted earlier, read the documentation on text() and the subsequent examples on annotation of graphs and about TeX if you're going to be doing this kind of thing; you can find out all there is to be done faster that way than waiting around for somebody at cs-sm to bail you out... --

Thanks And, of course, as another corollary lesson, try strrep('1x10^{-4}', char(215)) or strrep('1x10^{-4}', '\times') at the command line followed by help strfun for the more generic "how do I ..." re: string manipulations and help iofun for the universe that includes the earlier-noted sprintf() and friends... -- |
