I am running Centos 6.X on Oracle VirtualBox VM running on Win 7 host. I have successfully installed matplotlib-1.3.1 package for doing some numerical analysis in Python, but the matplotlib.pyplot doesn't show the output plot. I posted the question in a forum and they suggested to debug using `pyplot.savefig('fig.png')` instead of `pyplot.show()` which I have been using. I had installed `libpng-devel and freetype-devel` prior to my matplotlib installation as part of pre-requisites. However when I ran the aforesaid `pyplot.savefig('fig.png')` module, a "fig.png" file is saved but it's not opening or showing the picture (used command ~]$ less fig.png as well as installed ImageMagick but doesn't seem to work) . So I tried installing libpng-1.6.6 which needs freetype-188.8.131.52 as well as zlib and pkg-config.
