Temperature Profile Plots:
Lap difference needs X Axis = Distance and at least 2 selected laps.
Temperature profile plots are shown only when X Axis is Time or Distance.
Click "Combine From" on one segment, then "Combine To" on another to select everything between them, then merge them as one type below. Renumber a segment or give it a nickname directly in its row. Split by entering a fraction of the way through the segment (0.5 = halfway).

Use
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) + p4With Sinusoidal fit selected, click a point in the FFT chart to force the fit to that frequency.
