Failed plotting due to gazebo publishing incompatible timestamps on /clock

See original GitHub issue

Description Hi, I’d like to tune a PID controller within foxglove connected to my live ROS2 system via the ros-web-bridge. However it seems that I cannot get anything to come up in the plot. I’m fairly sure i’ve followed instructions but they only ever refer to plotting from a rosbag. A gif is attached here showing the value i’m trying to plot changing live, and the plot (which should at least show something):

foxglove debugging

Apologies in advance if i’ve missed a ‘start’ or 'enable instruction somewhere!

I have tried with a number of different topics, but nothing seems to come through!

  • Version: Foxglove Studio version 0.27.0, Ubuntu Desktop Version
  • OS: Ubuntu 20.04

Steps To Reproduce

  1. Start a live connection to ROS2 via the webbridge
  2. Create a plot and point it to some data. Observe that nothing is happening
  3. Use a raw panel to observe that data is actually coming through

Expected Behavior The live plotting of data points on the plot as it scrolls along

Actual Behavior Nothing gets plotted

Another thing I would recommend trying is to record a bag and try playing back the bag directly in Studio. If it has the same problem then you can just share the bag with us and that will make debugging much easier – if not, then at least that narrows things down a little.
