Log scales

Dear All,

I have a query about using log scales for filled.contour plots. I have 
used log values on the x and y axes but labelled the axes with their 
linear (non-log) values. I's like to do the same with the contour 
values. I want the range to go from -100% to +100%. To use log I just 
added 1000 to the % values before taking the log. I'd like the original 
% values to appear on the contour lines and in the contour colourbar 
labelling.

I'd appreciate any suggestions you have.

Many thanks,
Emily Gleeson
