Syntax:
plot '<file_name>' {binary <binary list>} ... splot '<file_name>' {binary <binary list>} ...
General binary format is activated by keywords in binary list pertaining
to information about file structure, i.e., array, record, format or
filetype. Otherwise, non-uniform matrix binary format is assumed.
(See binary matrix (p. ) for more details.)
NB: In previous versions of gnuplot there have been some differences between the interpretation of binary data keywords by plot and splot. Where the meanings differ, one or both may change in a future gnuplot version.
Gnuplot knows how to read a few standard binary file types that are fully self-describing, e.g. PNG images. Type show datafile binary at the command line for a list. Apart from these, you can think of binary data files as conceptually the same as text data. Each point has columns of information which are selected via the using specification. If no format string is specified, gnuplot will read in a number of binary values equal to the largest column given in the using list. For example, using 1:3 will result in three columns being read, of which the second will be ignored. Certain plot types have an associated default using specification. For example, with image has a default of using 1, while with rgbimage has a default of using 1:2:3.
