How to install matplotlib for Kivy?

[David Aldrich]

Hi

I want to use matplotlib in Kivy so I installed the garden matplotlib package:

garden install matplotlib

I also need to install matplotlib itself. I'm working on 64-bit Windows. I ran the matplotlib installer but it installed to:

C:\Python3.4

whereas I need it in the Kivy path:

"C:\Kivy-1.9.0-py3.4-win32-x64"

but I couldn't change the matplotlib installation path.

Following advice here:

https://groups.google.com/forum/#!searchin/kivy-users/matplotlib/kivy-users/aoSHpwpstLA/KKHnPc6GdH4J

I copied the mpl site_package files from the Python 3.4 installation to the Kivy 3.4 installation but then I see:

Traceback (most recent call last):

  File "backend_kivy.py", line 241, in <module>

    import matplotlib

  File "C:\Kivy-1.9.0-py3.4-win32-x64\Python34\lib\site-packages\matplotlib\__init__.py", line 116, in <module>

    raise ImportError("matplotlib requires dateutil")

ImportError: matplotlib requires dateutil

I think I am hacking rather than following a proper procedure. Please can someone tell me the proper way of installing matplotlib for Kivy 3.4?

Best regards

Hi

It would be really helpful to have some installation instructions for using MatPlotLib with Kivy.

I am now seeing:

C:\<snip>\gui\garden.matplotlib-master\garden.matplotlib-master\examples>python test_backend.py

 Traceback (most recent call last):

   File "test_backend.py", line 5, in <module>

     from kivy.app import App

   File "C:\Kivy-1.9.0-py3.4-win32-x64\kivy34\kivy\app.py", line 317, in <module>

     from kivy.base import runTouchApp, stopTouchApp

   File "C:\Kivy-1.9.0-py3.4-win32-x64\kivy34\kivy\base.py", line 30, in <module>

     from kivy.event import EventDispatcher

   File "C:\Kivy-1.9.0-py3.4-win32-x64\kivy34\kivy\event.py", line 8, in <module>

     import kivy._event

 ImportError: No module named 'kivy._event'

Any ideas please?

Hello,

You should try these using the unofficial windows binaries for numpy and matplotlib http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

I wrote a small tutorial https://andnovar.wordpress.com/2015/09/01/matplotlib-backend-kivy-in-windows-hands-on/

garden.matplotlib works with versions greater or equal to 1.9.1
