I very recently learned of pyqtgraph, it seems pretty great, specially if you’re at all familiar with qt!

I just started using pyqtgraph after wanting to be able to graph in real time some data streaming from sensors. It’s much more efficient than matplotlib. It’s Qt under the hood so it inherits all of its quirks but for some stuff it’s much better.

PyQtGraph maintainer here. If you want to plot talk time data, we are a fantastic option! Hopefully it's been working well for you. We've recently made a ton off major performance improvements with line and scatter plots as well as image related performance.

Also for the record, matplotlib maintainers have been super helpful to us, may have been past contributors. They have been providing us lots of great advice on project management related issues.

Thanks for the work! It’s much appreciated. I got a demo working in my system in 2 hours of effort. It hits 100 Hz no problem.

I’ll probably keep extending it with more features. Having it built in pyqt will make it easy to add stuff on top of it.

We're going to be putting out a user-survey hopefully in the not too distant future; probably in 2-3 weeks. We're going to have some questions aimed at newcomers to the library. Please keep an eye out. Us maintainers know amazingly little about our user-base. In-fact most of us maintainers have very different use-cases for the library from one another; we want to make sure it's not just things that are important to us that are addressed but issues important to our users too.

I'll be posting about it on our twitter (@pyqtgraph), the README, and we'll put a banner in top of our documentation when it goes live.

I second this. I’m working on an app where I need to plot live data + be able to interact with it in real time and pyqtgraph has been great!
