I\'ve installed Anaconda with the pkg installer:
Python 2.7.10 |Continuum Analytics, Inc.| (default, May 28 2015, 17:04:42)
[GCC 4.2.1 (Apple Inc. build 557
From the matplotlib documentation;
$ conda install python.app
You need a framwork build of Python for matplotlib, but
The default python provided in (Ana)conda is not a framework build. However, a framework build can easily be installed, both in the main environment and in conda envs: install python.app (conda install python.app) and use pythonw rather than python
NB I had to add the conda-forge channel as python.app isn't included in the default miniconda channels
$ conda config --add channels conda-forge
