Uploaded data files are saved in your browser. Use the buttons below to load them into the plotter.
Browsers can clear this storage under space pressure or after a period of inactivity. Asking for permanent storage makes that less likely (not a guarantee) -- Download All Data above is still the reliable backup.
Theme, panel sizes, math channels, data filters, and track corner/start-finish overrides.
Your saved vehicles and riders, as a standalone file -- to share a setup, or back it up separately from a full "Download All Data". Every vehicle/rider in the file is added as a new entry (existing ones are never overwritten). They're also already included in Download All Data above.
Optional: connect a Google Drive account to import CSVs from Drive and back up/restore from Drive, in addition to this device. Uses Google's restrictive "drive.file" scope -- this app can only see files it creates itself or files you explicitly pick.
t for the x-value, p0–p11 for fitted parameters (any subset, any order), and math names like sin cos exp sqrt abs pow PI. Example: a decaying cosine -- p0*exp(-p1*t)*cos(p2*t+p3) + p4
