Annotations in Igor Pro

Legends, text boxes and tags are all annotations, addressed by name.

Function Annotate(WAVE y)
    Legend/C/N=key/J/A=LT "\\s(y) measured\r\\s(fit_y) fitted"

    WaveStats/Q y
    Tag/C/N=peak/F=0/A=LB y, V_maxloc, "peak"

    TextBox/C/N=stamp/A=RB/F=0 "n = " + num2istr(numpnts(y))
End

How it works

1. Legend/C/N= replaces an annotation instead of stacking a second one.
2. Tag attaches to a point on a trace and moves with it.
3. \\s(trace) in the text draws that trace's own symbol.
