Logarithmic scales

I've got a graph that wraps around the 0 axis, thus having negative values. Any ideas on how to make this axis logarithmic and allowing for negative values?

Thanks

Hi.

By definition, for any logarithm defition range is (0,infinity) meaning only positive values are "good" values for this type of function. In your case I'd limit the axis range only to positive values. Or alternatively, show the log(|x|).
