Hi @renton.hsu.vfx. The constructor and ui.Plot.set_data() both want the list of data passed in as individual arguments. You need to unpack your list as args with the * operator: DAQ/extension.py at 23afdd6e4772b3be3e7bc8895472dc6aab61841e · kericbowman/DAQ · GitHub
I linked to this specific extension because it plots real-time data.
Let me know if you have any questions.
