[Gnuplot-info] how to break key and plotting

[pban92 <pb...@ya...>]

I have two things to solve and would highly appreciate if someone can help
me.

1. gnuplot default key is appeared "top to bottom" -wise. This is a problem
as in  http://old.nabble.com/file/p31089605/gnukey1.jpg  To avoid this, how
can I modify/break key something like this? 
http://old.nabble.com/file/p31089605/gnukey2.jpg 

2. Like 'hold' in matlab, is their any equivalent option that allows to plot
two graphs on the same window? For example, instead the following two lines,

plot        “case097.cor” every 2 t ‘S1' w p, \
	“case105.cor” every 2 t ‘S2' w p

How can I plot like,

plot        “case097.cor” every 2 t ‘S1' w p # plot on screen
<is there any option?>
plot        “case097.cor” every 2 t ‘S1' w p # plot on the previous screen
without deleting previous plot

(Please ask me if my problem is not clear)

Many thanks!

The key is the least of your worries with that plot.  It's quite 
completely unreadable.

You would need the development version of gnuplot for that, which has a 
'maxrows' option for 'set key'.  OTOH, you might be better of with just 
keeping the key out of the plotting area, where you don't have to worry 
about it occluding your data:

	set key outside

You're looking for 'multiplot' there.

i had a look at the newest gnuplot version, 4.4.3,
"announce.4.4.3" says:

* NEW set key maxcolumns N maxrows M

so these command options are now the official version.
