Hi, It is my first post to matplotlib-dev. I am a theoretical physicist interested a lot in Python/IPython/SymPy/NumPy/MatPlotLib/etc. Both for desktop OS and mobile OS. About mobile OS (for smartphones/tablets), MatPlotLib is packaged and works well in : - MeeGo 1.2 Harmattan OS on Nokia N9/N950, released in 2011, with Nokia N9 selling since September/October. MatPlotLib 1.0.0 was released yesterday by me (as a maintainer) : http://forum.meego.com/showthread.php?t=5231 http://talk.maemo.org/showthread.php?p=1128672 - Maemo 5 (Fremantle) OS on Nokia N900, released in 11/2009 and currently difficult to buy brand new. Install using "# apt-get install python-matplotlib" : http://maemo.org/packages/view/python-matplotlib/ NumPy, SymPy and IPython are also available for both OS. I have searched and found that there is no MatPlotLib for Android OS, iOS and Symbian. So it seems that the only smartphone selling today with MatPlotLib support is Nokia N9 (MeeGo 1.2 Harmattan OS). The repositories for Nokia N9 : http://harmattan-dev.nokia.com/unstable/beta3/Fremantle_Update7_vs_Harmattan_Beta3_content_comparison.html show about 170 Python packages. MeeGo Harmattan is also a developer's paradise, with more than 10 programming languages available now (via "apt-get install" or already installed) : gcc/g++ (3.4, 4.2, 4.4), gfortran 4.4, gpc (GNU Pascal 2.2), Lua 5.1, Perl 5.8, Prolog, Python 2.5/2.6/3.1, Ruby 1.8, TCL 8.4/8.5, Vala 0.12, etc. Also Qt/C++, Qt/Qt Quick, Qt/Python (PySide).
