Read local and remote decoded CAN messages I want, append to a file, plot to a GUI with some controls. Use it with [mycan](https://git.flylightning.xyz/mycan/).

build, install, and run
```sh
make
sudo make install
remote_plot
```

usage
```sh
# use default ssh destination
remote_plot
# use another ssh destination
remote_plot -d 10.0.0.7
# run locally
remote_plot -l
```
