Re: Can I put a legend on top of grid lines?

Hi Arne,

Thanks for providing a simple program that illustrates what you are talking about.

We actually have a trouble ticket for what you are requesting (NCL-148). I'll add your email to the ticket. Right now there's no easy way to fix this.

The method you've used below with the overlay call is probably the best work-around. It's similar to what we have in example 10 at:
