Re: Version GtkDatabox-0.9.1.0 released, new maintainer, RFC

Frequencies in the audio world are measured in octaves.  Filter parameters often specified as octaves.  Removing log2 would make audio engineers look for another library.  

Regarding libusb, I have used it in afew personal projects and you're right it is a standard, but there are a set of rules that free software should abide by.  I am really more interested in doing that, and listening to what users on this list think.  I'll admit I am new to managing large free software projects, and still have a good bit to learn.

libusb is at 0.1.12 now but is a standard lib de-facto.
I would personally hold the horses a little bit more.

About different bases for log format.
Out of curiosity where do you need log2-scaled graphs?
Log10 is a standard (engineering and scientific) logarithmic representation.
Once I thought that natural logarithm would be usefull but this was
in Origin where I fitter exp decay in logarithmic scale with linear function.
If it was a natural logarithm then the reverse coefficient is exactly
the decay constant and coefficient itself is a resonance [half]width.
But I can't imagine where such a scales could be usefull in a general
plotting widget as gtkdatabox.
Just imagine how would you represent ticks in nat logarithm scale?
e, e^2, e^3, ... How much is that, say e^4? Or e^{-3}?

Ok, I will keep in mind to update the FreeBSD port...

Just my 0.02$,
