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
