set palette file "-" binary record=64 using 1:2:3:4; ????

[Tatsuro MATSUOKA]

Hello

In the previous mail
http://www.nabble.com/Inquiry-of-Octave-to-pgnuplot-command-log-via-pipe-to15651002.html#a15651002

It should be too long to answer.

So I changed the question.

In the octave to gnuplot command via pipe,
I found the the commands;
 
set palette positive color model RGB maxcolors 64;
set palette file "-" binary record=64 using 1:2:3:4;
?€?>・E?>8?B>

(Of course binary part is not correct because this is text mail.)

In the gnuplot help

+++++++++++++
Binary palette files are supported as well,see binary general.Example:put 64 
triplets of R,G,B
doubles
into file palette.bin and load it by 
set palette file "palette.bin"binary record=64 using 1:2:3
+++++++++++
However, record causes gnuplot to not generate coordinate information. This is 
for the case where
such information may be included in one of the columns of the binary data file.
++++++++++++++

The log tell me  'using 1:2:3:4' not 'using 1:2:3'.
What the forth is ?

I cannot understand the what octave would like to do.
Please give me advises.

Regards

Tatsuro
