# This program is public domain """ Configure plotter for plottools. This must be imported first in __init__.py for plottools. If your application uses matplotlib outside plottools, then please do the following at the start of your application: # Select matplotlib version and backend import sas.plottools.config Note that plottools requires particular versions of matplotlib and a particular backend. As of this writing it is the WXAgg backend for matplotlib>=0.98. The plottools package uses pkg_resources if available to select the correct version of matplotlib. If you need multiple matplotlib versions in your path, be sure to use "easy_install -m" for all of them. If a version is installed without "-m" that does not meet the requirements, then pkg_resources.require() will fail, even if you have installed a suitable version with "-m". In this case you will need to fix up your site-packages directory, probably by removing site-packages/matplotlib and the associated egg file for that version, and reinstalling with "-m". You may also need to edit site-packages/easy-install.pth.
