Hi,
I find here two problems:
1. The second argument of g is expected to have head Real, while you call it
with the EXACT NUMBER 3 that has a head Integer, so g is not evaluated. This
can be solved by either
1. Calling g with 3.0 (or 3.) and not 3
2. define g as g[X_String,w_(Real|Integer),f_]:=...
or
3. define g as g[X_String,w_?NumberQ,f_]:=...
after fixing this, the PlotRange->All in the first example is not "tall"
enough to show the required "X" string so you need to move from All to more
sepecific value for the vertical axis
regards
yehuda
