[Gnuplot-info] printing a string

[Francky L. <Fr...@Le...>]

Dear,

I tried numerious changes to the following and don't find a solution.

f1 = 1.2
sf1(f) = sprintf("f1 = %2.2s%c", f)
print sf1(f1)

rotation_angle = 90
dB_offset = 10
set label f1 sf1(f1) at f1, -dB_offset right rotate by rotation_angle 
font "Helvetica,12"

Errors appear. Why? What is wrong?

Regards,

Francky Leyn
