How To Install python-qwt on Debian 9
Introduction
In this tutorial we learn how to install python-qwt on Debian 9.
What is python-qwt
python-qwt is:
The qwt package is a pure Python implementation of Qwt C++ library with the following limitations.
The following Qwt classes won’t be reimplemented in qwt because most
powerful features already exist in guiqwt:
- QwtPlotZoomer
- QwtCounter
- QwtEventPattern
- QwtPicker
- QwtPlotPicker
QwtClipper is not implemented yet (and it will probably be very difficult or 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).
This is the Python 2 version of the package.
