Hello,

I would like to print a function in the key like this:

f11(x) = -2.56·x - 103.63

I use the following code in the plot command for that:

f11(x) lt 2 lw 4 dt 4 t sprintf("f11(x) =%6.2f·x%+7.2f",a,b11)

That means, that I use the sign from the format specifier as plus sign
or minus sing in the printed function. But than I don't have a space in
front of the second number. The second number can be positive or negative.

Jörg
