Hi,

I have processed measurements of a rough surface to a heigh-height
correlation plot. What the meaning of this exactly is, is not important.
Only that it is a plot that had two (almost ) linear parts when plotted on a
logaritmic scale. In this plot, I want to draw the best fitting lines for
these linear parts but I just can't get it done. It is easy when the scales
are linear but as you might have imagined, the scales being logarithmic
don't add to the simplicity of my problem.
Thanks in advance!

Joren
