In my video, I have an angle being traced and it looks good in the video but thoes angles are not the ones being plotted. For example the video shows a 60 deg angle but that data point cant be seen on the graph.

I think the discrepancy is because the ones on the video viewport don't take the smoothing filter into account for performance reason. If you disable all the smoothing in the preferences they should match again. But the smoothing is important for accuracy, to remove digitization noise. The main thing I want to avoid is recalculating the whole series on every frame during tracking and point manipulation, maybe it could update whenever the track exits editing mode.
I have turned off the smoothing and the issue is still there. The plot is off by about 30 degrees, I don't think is a smoothing issue. In this video im tracking 2 different angles and the first one is perfect, its just the second one that isnt working

Is it a normal angle object or is it an "angle-to-vertical" or "angle-to-horizontal" object?
There was a bug with the latter that was fixed in 2025.2.

Oh, I forgot to update the little file that tells what's the latest version. It should be fixed now, you can try again.
Or you can get it from here: https://kinovea.org/download/
I'm sorry! That didn't work either. The graph also changes depending on where the video is stopped when I click on "angular kinematics". Again, this is only happening for one if the angles in the video
