Hi,
I just created a plot with a legend in new graphics (NG). LEGEND function requires that the NAME keyword is assigned to each plot command. My names include units so include the "/" character. However, IDL 8.3 returns "The identifier property value cannot contain '/' characters." Does anybody know if there is a way to escape this?
Thanks,
Haje

Here is Chris's response:
Yes, unfortunately, this happens because the "/" is used to separate the
different object graphics pieces, just like a directory separator.
But the easiest solution is to just use the "LaTeX" / character instead,
like this:
p = plot(x, y, name='2008 $\slash$ 2009')
l = legend()
Notice that I put an extra space before and after the slash character.
At least on my Mac, if you don't have the space, it doesn't leave enough
room around the slash. Maybe because it is a Unicode "math" character.
Also, I used single quotes so it doesn't think the 2008 is some sort of
weird octal number.

Thank you so much for the quick solution. I could not find the post you referred to, so I am glad you found this. Haje
