Ben, on master scatter legends are broken. A pull request (I can't remember
which, and github is down, possibly #1176) fixes this (obviously, the PR is
marked as release critical for 1.2).
I have confirmed, that even once fixed on master, the scatter legend
handler does not take notice of the "numpoints" kwarg.
Hope that helps clarify the matter,
Regards,
Phil

Which directions? We have several for different kinds of installs. We have
not released v1.2.0 yet, so I was guessing you checked out mpl from
github. If that is the case, then you run "git log" from the source
directory, not the install directory.

Hi Ben,
I think I installed this version by following the instructions on
matplotlib website. But when I try to use git log, I get:
chaoyue@chaoyue-Aspire-4750:/usr/local/lib/python2.7/dist-packages/matplotlib$
pwd
/usr/local/lib/python2.7/dist-packages/matplotlib
chaoyue@chaoyue-Aspire-4750:/usr/local/lib/python2.7/dist-packages/matplotlib$
git log
fatal: Not a git repository (or any of the parent directories): .git
I tried to have a look at __init__.py, it has:
from __future__ import print_function
__version__ = '1.2.x'
__version__numpy__ = '1.4' # minimum required numpy version
So it's the correct directory I am going. could you give some further
instructions?

Strange, when I tested it last night, I was using a build of mpl from
master of a couple weeks ago, and I saw three markers in the legend. Now,
I am trying it again with the latest master:
1478a1be70b3077b71350cecaccb774f76a76656, and I now see *zero* markers.
Something is seriously broken.
Can you tell me what commit (and the date for that commit) shows up at top
when you run "git log" in the mpl source directory?
Ben Root

Dear Ben,
I tried again with dev version and GTKAgg backend it works.
In [3]: mat.__version__
Out[3]: '1.2.x'
In [4]: mat.get_backend()
Out[4]: 'GTKAgg'

Hi Ben,
I tried the "numpoints" in legend function for scatter plot, in dev version

Announcement - mplstereonet v0.2
=========================
mplstereonet provides lower-hemisphere equal-area and equal-angle
stereonets for matplotlib.
Download
--------------
Available for download at: http://pypi.python.org/pypi/mplstereonet/0.2
See the github page for more information and development versions:
https://github.com/joferkington/mplstereonet
About
---------
Stereonets are a type of plot commonly used in the geosciences for
visualizing and analyzing orientation data.
Orientations of linear and planar features are plotted as the intersection
of the feature with a hemisphere. (Therefore, linear features plot as
points and planar features plot as lines.)
mplstereonet provides plotting of planes (measured as strikes and dips),
poles to planes, and lineations (measured as rakes along a plane or as
plunges and bearings).
Additionally, mplstereonet provides orientation density contouring using a
variety of standard methods (e.g. "Kamb" contouring, etc).
Getting Started
----------------------
The easiest way to get started is to have a look at the examples:
https://github.com/joferkington/mplstereonet/tree/master/examples
Additionally, the readme has an overview and various examples:
https://github.com/joferkington/mplstereonet/blob/master/README.rst
Changes
-------------
New features in version 0.2 include:
- Density contouring of orientation data using a variety of methods
- Equal-angle as well as equal-area stereonets
- A variety of parsing utilities
- Geometric analysis utilities (e.g. plane intersections)
Thank you all very much!
