Hi all,
Fumbling around trying to find a plot package to do 3D plots.
This will be an aid to separating bats by their vocal signatures.
What I need to do is plot *Fc *against *Sc* with the third dimension
being the *density* of the data points in the Fc-Sc plot.
Data format is like this abbreviated sample. Fc is a frequency in kHz
and Sc is the characteristic slope (octaves per second) of each call pulse.
Any suggestions, guidance greatly appreciated.
