matplotlib_qtquick_playground

Port of the example kindly provided by Eli Bendersky to PyQt5: https://github.com/eliben/code-for-blog/tree/master/2009/pyqt_dataplot_demo

Derivation of the example have been made based on the three following Qt technologies:

The goal of this work was to play around with QtQuick and PyQt5. The integration of matplotlib with QtWidgets is the best as a backend support full interactivity and navigation toolbar. A new matplotlib backend based on a QQuickItem has been created to restore maximal interactivity.

The logic behind QtWidgets GUI and QtQuick is quite different. For example, in the former, the Python script takes care of reading all widgets before updating the figure. But in the latter, QtQuick controls are binded to Python properties that emit signal forcing the figure to update.

Code functions

Series of data are loaded from a .csv file, and their names are displayed in a checkable list view. The user can select the series it wants from the list and plot them on a matplotlib canvas. Use the sample .csv file that comes with the scripts for an example of data series.
