Displaying EMG (Electromyography) with PyQT Python

Question

I have to display an elecromyography (it's like an electrocardiogram) based on values i get from another file. Is there any widget in python Qt which will allow me to do that ?

What i want is something which will look like this picture :

Example of EMG

So, a graph based on the time (x) and voltages (y)

Thx for your help !

Answer 1

There is no built-in widget that will directly give you anything as complex as an EMG graph, so you would have to write something yourself using Qt's Graphics View Framework , which would obviously be quite a lot of work.

For out-of-the-box solutions, you could try something like Qwt (Qt Widgets for Technical Applications), for which PyQwt provides python bindings. Or there's also matplotlib , which has a backend which provides support for PyQt/Qt.

UPDATE :

As has been pointed out, there's also PyQtGraph . But rather than list all the possibilities here, it would probably be easier to just point you towards the Graphical Representations of Data page on the Python Wiki.
