A simple solution

Preben Alsholm — Fri, 15 Feb 2013 21:50:20 Z

If you can live with a parenthesis aound the exponent then beta=10^``(-6) is a solution.

A rather weird way:

ten:=convert(10,symbol);
ten^(-6); #Doesn't do it, but:
series(ten^(-6),ten);

legend

If you're willing to write out the `legend` entries by hand (or do a little coding to manipulate given values of the parameter), you might try it like,

  legend=[typeset(Beta[0]=10^(-``*9))]

That should give you 9 in an upright font. Using 10^(-`9`) would show the 9 in italics, a mismatch with the upright 10. And 10^``(-9) would display with surrounding brackets.

Two other simple solutions

If you can live with 1.10^-8:

textplot( [1,1,typeset(beta=1e-8)] );

Or, without the 1. before the 10^-8

textplot( [1,1,typeset(beta=` 10`^` -8`)] );

(mind the spaces!)

Logarithmic tickmarks

Carl Love — Fri, 15 Feb 2013 22:47:13 Z

Regarding your question about the tickmarks: Each tick on the horizontal axis of the plot that you posted represents a separate power of 10, so it is appropriate that those ticks are linearly spaced. The ticks on the vertical axis of that plot that are logarithmically spaced. If you use a narrower range on the horizontal axis, you will get logarithmic ticks there also. You can achieve much finer control of the tickmarks by using some options to the plot command (see ?plot,tickmarks), but this can quickly get excessively complicated.

Thanks to everyone, all of these solutions worked! I'd rather the exponent didn't have brackets, so for my purposes I think acer's solution was the best. Didn't know anything this simple could get complicated. Aren't there any plans for the maple team to give us more control over the plot legend, so we can place it anywhere we want?

You're right, I didn't realize that the vertical axis had logarithmic ticks for some reason. Thank you
