This was tested to be ~40x SLOWER than a similar pyqtgraph graph
PROJECT PAGE: http://www.swharden.com/wp/2016-07-30-live-data-in-pyqt4-with-matplotlibwidget/
This is a minimal-case example how to get a PyQt4 GUI (designed with QT Designer) to display a matploblit widget and update it automatically. This was tested with the WinPython 3.x distribution, but should be cross platform. Read the parent readme for full project details.
- edit the ui_main.ui with "Qt Designer"
- run ui_convert.py to turn ui_main.ui into ui_main.py
- run go.py to launch the program (pulling UI from ui_main.py)
- if the "keep updating" box is checked and the add buttin is hit, it does more and more!
If you get ImportError: No module named 'matplotlibwidget', ensure you are in the same folder as matplotlibwidget.py which is now provided with this example.
