[Gnuplot-info] key problem

[farrokh y. <you...@gm...>]

Hi all

I intend to set only key "Myplot" to my graph with :

set key off
set key inside right top title "Myplot" box lt 4
plot sin(x)

But it is appeared one another unwanted key as "sin(x)----".

How to delete this unwanted key?

Thank you
Farrokh
