How can I make a parametric 2d plot with both axes logarithmic.

After using NDSolve on two coupled differential equations, I want to
plot the two solution functions against each other on a logarithmic plot.
I know that I can plot the logarithms of the solutions with
ParametricPlot, but then the axes are marked with the logarithms of
the functions, not the values of the functions themselves. I want the
values on the axes to be like when using LogPlot (0.1, 0.01, 0.001, ...)

Thanks,
Torquil Sorensen

Torquil,

You could probably use LogScale from the Graphics`Graphics` standard package
as a Ticks or FrameTicks function. You could also try the DrawGraphics
package from my web site below. It has CustomTicks and CustomGridLines
functions that allow almost any kind of plotting scale and with more
control.
