[Matplotlib-users] backend_qt4agg

[john p. <jp...@ma...>]

Users,
I am working on Windows 7 with QGIS 2.4. I am trying to get a plugin 
installed in QGIS called Semi-Automatic Classification Plugin to work. 
The plugin is demonstrated here:
http://fromgistors.blogspot.com/2013/07/working-with-multispectral-bands-in-qgis.html

The first time I tried to install the QGIS plugin, I got an error 
message that backend_qt4agg was not installed. I installed Python(x,y) 
with Python 2.x, because it seemed like the easiest way to get 
matplotlib and a bunch of other apps/extensions installed at the same 
time with minimal effort. I am not a programmer and I'm not familiar 
with installing things from source and then configuring settings. After 
the Python(x,y) install, I went to QGIS and started again and tried to 
install the plugin. I got the same error message. Please tell me what I 
need to do to get this backend installed in order to get the QGIS plugin 
I want.
