Can you provide more details?

Perhaps you can include some example code demonstrating the problem?

have you tried: set title "<your title>"?

The title in the plot command is used in the key, but you use "nokey".
If you use "set key" instead of "set nokey" than your "line titles" will
be displayed in the key.
