70 SET-SHOW gnuplot 4.3 89
set bars {small | large | fullwidth | } {front | back}
unset bars
show bars
small is a synonym for 0.0, and large for 1.0. The default is 1.0 if no size is given.
The keyword fullwidth is relevant only to histograms with errorbars. It sets the width of the errorbar
ends to be the same as the width of the associated box in the histogram. It does not change the width
of the box itself.
The front and back keywords are relevant only to errorbars attached to filled rectangles (boxes, candlesticks,
histograms).
70.5 Bmargin
The command set bmargin sets the size of the bottom margin. Please see set margin (p. 112) for
details.
70.6 Border
The set border and unset border commands control the display of the graph borders for the plot
and splot commands. Note that the borders do not necessarily coincide with the axes; with plot they
often do, but with splot they usually do not.
Syntax:
set border {} {front | back} {linewidth | lw }
{{linestyle | ls } | {linetype | lt }}
unset border
show border
With a splot displayed in an arbitrary orientation, like set view 56,103, the four corners of the x-y
plane can be referred to as "front", "back", "left" and "right". A similar set of four corners exist for
the top surface, of course. Thus the border connecting, say, the back and right corners of the x-y plane
is the "bottom right back" border, and the border connecting the top and bottom front corners is the
"front vertical". (This nomenclature is defined solely to allow the reader to figure out the table that
follows.)
The borders are encoded in a 12-bit integer: the bottom four bits control the border for plot and the
sides of the base for splot; the next four bits control the verticals in splot; the top four bits control the
edges on top of the splot. In detail, should be the sum of the appropriate entries from the
following table:
Graph Border Encoding
Bit plot splot
1 bottom bottom left front
2 left bottom left back
4 top bottom right front
8 right bottom right back
16 no effect left vertical
32 no effect back vertical
64 no effect right vertical
128 no effect front vertical
256 no effect top left back
512 no effect top right back
1024 no effect top left front
2048 no effect top right front
Various bits or combinations of bits may be added together in the command.
