Qt plotting widgets for Python

Project description

The PythonQwt project was initiated to solve -at least temporarily- the obsolescence issue of PyQwt (the Python-Qwt C++ bindings library) which is no longer maintained. The idea was to translate the original Qwt C++ code to Python and then to optimize some parts of the code by writing new modules based on NumPy and other libraries.

The PythonQwt package consists of a single Python package named qwt which is a pure Python implementation of Qwt C++ library with the following limitations.

The following Qwt classes won’t be reimplemented in qwt because more powerful features already exist in guiqwt: QwtPlotZoomer, QwtCounter, QwtEventPattern, QwtPicker, QwtPlotPicker.

Only the following plot items are currently implemented in qwt (the only plot items needed by guiqwt): QwtPlotItem (base class), QwtPlotItem, QwtPlotMarker, QwtPlotSeriesItem, QwtPlotHistogram, QwtPlotCurve.

The QwtClipper class is not implemented yet (and it will probably be very difficult or even impossible to implement it in pure Python without performance issues). As a consequence, when zooming in a plot curve, the entire curve is still painted (in other words, when working with large amount of data, there is no performance gain when zooming in).
