Yo John!

BTW, what version of gpsprof are you suing?  That looks pretty old?

Odd as it seems, looks right to me.  Using %.9f lat/lon, and your data is
only +/- a few mm, that is only a few dots high.

gnuplot makes the simple trivial, and the slightly more difficult a real

The way to play with this is to hand edit the acii plot file until you
get what you want.  Then figure out how to modify the code, or jsut send
what works to me and I can do that.

Notice on line 600, that autoscale is set:
        fmt += ('set autoscale\n'

Sometimes that is easy to change, usually it becomes a large mess.

Maybe try:
        set autoscale x
        set yrange YYY

You can easily lose a few days down that rabbit hole.
