How do you use gnuplot embedded fonts?

Question

In gnuplot docs there is this to say about fonts:

    Five basic fonts are supported directly by the gd library. These are
    `tiny` (5x8 pixels),` small` (6x12 pixels), `medium`, (7x13 Bold), 
    `large` (8x16) or` giant` (9x15 pixels).

But when I try to use one:

    gnuplot> set terminal png font tiny

I get:

    Could not find / open font when opening font tiny, using default

How to use these seemingly built-in fonts?

Answer 1

The problem was that for these fonts for some reason you are not using the standard syntax that I used above:

gnuplot> set terminal png font tiny

Instead, you drop the word "font" for these five special fonts:

gnuplot> set terminal png tiny
