View Full Version : QWT introduction

27th September 2007, 09:33

The helpdesk has recently installed (thats what they said) qt, qwt, pyqwt and pq on my linux SUSE 10.1
I can work fine with qt and py, but how do i work with QWT?
Does QWT have a user interface? Is it inside of qt?

After a measurement i obtain data in a long list, i want to plot this data in a 2D graph using qwt. What i dont understand is how qwt works.
Is there a simple tutorial just illustrating how to use qwt and create a graph, could someone please make one, ive searched everywhere.
thanks a lot.

Qwt is a library, so if you want to use it, you have to write an application. There is a number of examples available with Qwt --- check them out.

Sorry about that, wasnt sure where to post.
What do you mean writing an application, cant i just use Qt?
And where can i find those examples?

Like Jacek said, QWT is a library. If you have installed QWT you should have a folder with examples in it. I've used QwtPlot for my real-time graphs.
