Multiple plots with different scales in one graph.

How do I ...? with Maple

Is there a way to plot a single graph with multiple functions, where I can set a different scale for each function?
I want to get something similar to this:
<a href="http://www.mapleprimes.com/viewfile/2818"><img alt="" src="http://www.mapleprimes.com/scripts/image.php?image=http://www.mapleprimes.com/files/9471_plot.png&width=300&height=300" /></a>
I can plot multiple functions in one graph with display(); but it is the multiple scales part that's giving me a headache...
 
Thanks
Thomas

One of the new features in Maple 12 is the ability to create plots with two different scales. Here are three examples from ?plots[dualaxisplot]. Note that the second one is an animation. Very nice, even though I'm not sure these plots have a whole lot of meaing in and of themselves.

dualaxisplot(plot(x^2, x = 0 .. 10, labels = [x, x^2], legend = x^2), plot(x^3, x = 0 .. 10, color = blue, labels = [x, x^3], legend = x^3));

dualaxisplot(animate(plot, [A*x^3, color = blue, labels = [x, x^3]], A = 0 .. 1), plot(x^2, labels = [x, x^2]));

dualaxisplot(inequal({x-y <= 1, 0 < x+y}, x = -3 .. 3, y = -3 .. 3, optionsexcluded = (color = white)), conformal(z^2, z = 0 .. 2+2*I));

I hope this is helpful.
