Upload up to 10 TXT (or CSV) files that include at least the fields TIME_CODE, ALTITUDE, LATITUDE, and LONGITUDE. For each file the row with the maximum ALTITUDE is used to compute an Adjusted_Time_Code (by shifting its TIME_CODE so that the altitude peak of every file lines up with that of the first file). You may then choose any available field (including Adjusted_Time_Code) as the x‑axis and any other as the y‑axis. Each file’s series is plotted in its own color (with a legend), and a track map of the flight path is drawn below.
