Use the LINSIZ Ekeyword. For example, set linsize = 0.5 to make the lines half their default length. --Wayne

Well, maybe I can answer this question! How about something like
this:
lines = indgen(6)
items = 'linestyle '+strtrim(lines,2)
cgplot, dindgen(10)
al_legend,items,linestyle=lines, charsize=2, pspacing=1.0
Cheers,
David

Ah, OK, I see what you mean.
But, now we are out of my domain of expertise entirely, and
we enter Wayne's realm. He will be in touch with us shortly,
no doubt. :-)

OK, if you try this:
IDL> lines = indgen(6)
IDL> items = 'linestyle '+strtrim(lines,2)
IDL> plot, dindgen(10)
IDL> al_legend,items,linestyle=lines, charsize=1
You'll see that a plot with a legend will appear, where in the legend
there are some lines with different styles. The charsize specifies the
font size in the legend.
Now if you try
IDL> al_legend,items,linestyle=lines, charsize=2
another legend will appear on the top, with larger fonts and longer
lines.
Now, I would like to be able to change the font size, so to make my
labels readable, but not having gigantic lines.

I have no idea what you are talking about! What, exactly,
are you trying to do? :-)
Can you show me an example?

OK,
but the bottom line is:the number keyword cannot decrease the length
of my lines under a certain value.
this value is set by charsize, in the sense that:
charsize increases ----> length of lines increases

Now that I look more closely at your error, I would

Well, I don't know. I'm running in IDL 7, too.

Works fine here. Did you download the latest this morning?

I would say you probably have a programmer error. :-)

Yes, that will be VERY old. I'd get the latest AL_LEGEND
from the NASA Library. :-)

I don't believe there *is* a built-in LEGEND procedure
in IDL 7, and I don't know much of anything about Ray
Sterner's routines, except that it would surprise me
a GREAT deal if one of Ray's programs didn't work in
PostScript!
All that said, I think most people use AL_Legend
from the NASA Astronomy Library:
