Using Anaconda Python 3.4 with PyQt5

matplotlib anaconda python-3.4 pyqt5

I have an existing PyQt5/Python3.4 application that works great, and would now like to add "real-time" data graphing to it. Since matplotlib installation specifically looks for Python 3.2, and NumPhy / ipython each have there own Python version requirements, I thought I'd use a python distribution to avoid confusion.

But out of all the distros (pythonxy, winpython, canopy epd) Anaconda is the only one that supports Python 3.4, however it only has PyQt 4.10.4. Is there a way I can install Anaconda, and use matplotlib from within my existing PyQt5 gui app?

Would I be better off just using another charting package (pyqtgraph, pyqwt, guiqwt, chaco, etc) that might work out of the box with PyQt5/Python3.4?

I was able to install it from dsdale24's and asmeurer's channels but then, when trying to run a qt script with a QApplication object, I got an error message regarding to cocoa library not being found.

Then, following asmeurer's comment, I could install PyQt5 on anaconda with python 3.4 using the mmcauliffe package:

conda install -c https://conda.anaconda.org/mmcauliffe pyqt5

Now it works great!
