  Usually, your data reading code will keep inserting data to the dataset.

  Then in your screen you can have control setup the "Refresh interval" of chart, and use Timer component to call redraw of chart region for your data.

  IMO, calling .TriggeredUpdate() for every single piece of data received is going to fail because UI update tends to be slow operation compared with your "150 nanosecond" interval. (Normal LCD refresh at 60Hz, that is 16666666.67 ns per frame)

  The forums issues have been resolved but it appears there are a few threads or posts on 08/18/2019 that are casualties. I've been asking about them but it appears so far there's no interest in fixing them.

  update: they say they're still working on it

  The broken threads I'm aware of have all been fixed.
