work in progress
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
```
Infrastructure configs, some maybe included in pi_config dir
- I prefer manage infrastructure configs using my [cfg](https://git.flylightning.xyz/fsh/tree/sh/cfg) script, but that script is my personal project and I don't want to force people to use that, so I include those config files in this repo and I did not manage it with my cfg script on raspberry pi.
- raspberry pi
- ~/.config/labwc/autostart autostart remote_plot locally
- <https://wiki.archlinux.org/title/Labwc#Autostart>
- /etc/wireguard/wg0.conf wireguard config
- /etc/NetworkManager/system-connections/wg0.nmconnection, networkmanager wireguard config imported from wireguard config
- /etc/modules-load.d/wireguard.conf autostart load wireguard kernel module, see <https://wiki.archlinux.org/title/Kernel_module#systemd>
- /etc/nftables.conf nftables firewall configs
- server and laptop:
- wireguard related configs
- files in /etc/wireguard, see below
- files in /etc/NetworkManager/system-connections
- /etc/nftables.conf nftables firewall configs

- laptop: <https://git.flylightning.xyz/config_local_arch/tree/etc/nftables.conf?h=master>
- Reboot or restart/reload the services maybe needed for some configurations to work.

remote_plot future improvements
- Line plot
- Use a slider for time
- Time in current timezone
- Show data number on plot
- Webui with rest API
- Save little to RAM, read from file mostly
- Server side record data
- Better network hole punching
- Better UI
- Specify to plot last how many last seconds
- Async read remote data
- Plot average data in a time period to use less CPU
- Scroll-able plots
- Show cell name for max min data
- Better way to manage infrastructure code
- More touch screen friendly
- More platform independent
