Maybe helpful for others trying to use large legends (or legends with
lot of markup stuff):
On systems with snprintf, the length of the legend "input" (before
markup) is truncated to 200 chars, which might not be long enough in
some cases (at least not for me at the moment). This is more a "hack"
rather than a real fix (which would probably to use dynamically
allocated buffers, but gives some more room for fancy formatted legends.
Cheers,
Markus
