symlog linear to log transition plot position?

Hi I need to use the symlog yscale in my graph, I have a lot of data 
that needs to be displayed linearly, with a small fraction at the upper 
end of the range that needs to be displayed in log scale due to its 
distance from the main data.  The symlog scale works great, however I'd 
like to adjust the actual vertical graph position where it crosses from 
linear to log (not the threshold), because right now only ~25% of the y 
space is being given to linear, and I'd like it to be more like 80%.  Is 
this possible?

Thanks!
David

Isn't linthreshy what you are looking for?  It denotes the range where the scale is linear.  So, if it is 25, then from -25 to 25 the scale will be linear.  After 25, it will be log.

Maybe I am missing something in your description?

Cheers!

I can confirm your results.  I am looking into it.  What version of matplotlib are you using?

Documentation

Hi,

The documention on building matplotlib from source (
http://matplotlib.sourceforge.net/users/installing.html )
says the following :

"If you are on debian/ubuntu, you can get all the dependencies
required to build matplotlib with:
sudo apt-get build-dep python-matplotlib"

However, doing so will force use to install over 800Mo of useless packages.
The dependencies mentioned after that (pytvhon,numpy, libpng,
freetype) are sufficient for building from source.
Could you edit that ?

Thanks

Re: Documentation

Actually, you will still need "python-dev" for compiling.

Sorry.

Re: Documentation

Can you provide a list of all of the packages that "apt-get build-dep 
python-matplotlib" installs?  I think there's more required than what 
you listed.  For example, it installs a C++ compiler, which is 
required.  We can't assume the user has anything already, which is why 
build-dep is so convenient.

tight_layout() causes RuntimeError on OSX

Hey guys, I'm trying to use tight_layout() to fix up some subplot grossness, but whenever I call it, I get:


Traceback (most recent call last):

I've googled around, but no answers have been found.  Is this a known issue, and if it's not, how can I go about fixing it?
Thanks,

When I run the macosx backend (which appears to be what you're using), I get the following output:

    tight_layout : falling back to Agg renderer

and the figure appears to be rendered with TkAgg . So it appears that it's a known issue on the macosx backend. And, apparently, the suggested work-around is to use an Agg backend.
