Hi all,

I just stumbled over the following trying to add a title to a plot:

<hansl>

set verbose off

nulldata 10

series y = normal()

scalar a = 0.98

gnuplot y --time-series --output=display \

  {set title sprintf("Some statistics = %.2f", a);}

<>

As you can see, I tried to apply the handy expression using the sprintf() function. It does _not_ provike an error, but the value of  `a` is printed as `nan`.

Is sprintf() actually supported? If not, I guess an error should be thrown.

If it actually is supported, the right value of a should be printed.

Thanks,

Artur
