Adding some new transformations to gnuplot (arctan and power laws)

[Dean F. <dea...@gm...>]

Hello people;

I'm new to the gnuplot mailing list, so I don't know the ropes around
here.  I've been working on adding some other transformations to
gnuplot.  I needed them for some research I was doing, and thought
they might be of general interest.  The idea is to have a variety of
ways to transform the axis.  Currently gnuplot supports linear and
log.  I've written some code that will do arctan and a variety of
power transformations.  So I'd be happy to submit these back to
gnuplot, but haven't ever done something like that.  Since I haven't
seen any patches being sent on this news group so far, I'm not sure
what the style is either.

As an example of the type of plot you can make using these
transformations, I made a graph for the wikipedia:

http://en.wikipedia.org/wiki/Law_of_the_iterated_logarithm

It could have been made using the existing version of gnuplot by
precomputing the axis and then just adding artifical tics as needed.
But the advantage of my code is that you can try different
transformations in real time by clicking on the graph and / or using
command line changes along with replot.  I've found this to be quite
fun actually.  Kind of sad what statisticians think as "fun."  :-)

So please let me know how I should proceed.

thanks,

dean


p.s.  I tried writing up documentation, but I couldn't seem to make
any changes that ever made it back into my local version of gnuplot.
It appears I deeply don't understand texi/doc.  So for a starter,
which file should I be editing?
