The fancy website: https://plotjuggler.io/

Just popping into say we love your behavior tree project, and are assessing it for some work projects. If we do we will definitely be sponsoring your work. Thanks for helping push the ROS ecosystem forward!!!

Get in touch, I will be happy to hear more about it :D

cool! another neat project based on Dear ImGui that i follow is https://github.com/epezent/implot . i'm a bit of a timeseries enthusiast. if you need something for the web, check out https://github.com/leeoniya/uPlot EDIT: sorry, didn't mean to highjack the thread :(, all glory to /u/facontidavide!

we got the best results from server side rendering graphs and just dynamically updating the front end with new images. Scrolling around, zooming etc is actually really snappy.

i believe it! certainly a viable option in many cases.

any public demo?

I've been using PlotJuggler for a good couple of years now and it's one of the go to tools for debugging robotics systems for me. I'm sure it had saved me a good couple of days of my life!

I clicked on this link just out of curiosity but was delighted to see that it has support for PX4 ulog right out of the box! Pretty good chance this is going to become part of my daily workflow while working with autonomous drones!

May I ask what's the workflow like with this?

It’s quite simple with ROS - you open a bagfile or connect to ROS, select the topics of interest and then you can plot the values.

An example of the top of my head for debugging: the robot I was working with was not very eager to turn on the spot, by plotting commanded angular velocity vs angular speed from wheel odometry I was able to see that commanded velocity was fine and the issue was on the motor controller level.
