Plot a file instantly.
CSV, Excel, a CAN log or audio — the chart is on screen the moment you load it. No script to write, and nothing leaves your machine.
Instant
No processing screen, no wait, no script to write. Drop a file and the chart is already there.
Many formats

A licence includes a download of Plotafile that works offline. Save it once and it runs forever without this site. Your key is checked on your own machine, so it keeps working whatever happens here.
