removing duplicate keys for multiple histograms

[Laurence D. <ld...@mi...>]

Hello,

Using newhistogram to have several histograms on one plot, I'd like to
be able to turn off keys for certain histgrams, is this possible?

The keys for each histogram on my plot are identical, so I'd like to be
able to turn off all but the first and save some space.  Would manually
turning off keys be the best way or could gnuplot detect they are the
same (same colors too) and omit duplicates?

Thanks,
Laurence

Syntax is from the cvs version, but the principle should be clear:

plot newhistogram "One", for [i=2:5] 'immigration.dat' using i, \
     newhistogram "Two", for [i=2:5] '' using i notitle, \
     newhistogram "Three", for [i=2:5] '' using i notitle

Thanks that does exactly what I want :)

Shouldn't the option "notitle" be called "nokey" instead, because it's
making the keys disappear and the titles are still underneath each
histogram?

You are focused on histograms, but the "notitle" option applies
to all plot types and has been part of gnuplot syntax since
approximately forever.  

Yes, histograms have a separate object that is obviously a 'title',
set by the "newhistogram" command. But all other plot types have
only the title that appears in the key.

No.  The things underneath the histograms aren't titles, they're tick 
labels.  The thing that becomes a part of the key is the title for that 
dataset.
