## Demo:
### Streaming
To get started exploring and plotting data live in your car, you can start PlotJuggler in streaming mode: `./juggle.py --stream`.
For this to work, you'll need a few things:
- Enable tethering on your comma device and connect your laptop.
- Run `export ZMQ=1` which tells the streaming plugin backend to use ZMQ. If you're streaming locally, you can omit this step as ZMQ is used to transport data over the network.
- Most importantly: openpilot by default uses the MSGQ backend, so you'll need to [ssh into your device](https://github.com/commaai/openpilot/wiki/SSH) and run bridge. This simply re-broadcasts each message over ZMQ: `./cereal/messaging/bridge`
Now start PlotJuggler using the above `juggle.py` command, and find the `Cereal Subscriber` plugin in the dropdown under Streaming. Click Start and enter the IP address of the comma two. You should now be seeing all the messages for each [service in openpilot](https://github.com/commaai/cereal/blob/master/services.py) received live from your car!
## Demo
For a quick demo, go through the installation step and run this command:
