36.7 Boxwidth
The set boxwidth command is used to set the default width of boxes in the boxes, boxerrorbars
and candlesticks styles.
Syntax:
set boxwidth {} {absolute|relative}
show boxwidth
If a data file is plotted without the width being specified in the third, fourth, or fifth column (or using
entry), or if a function is plotted, the width of each box is set by the set boxwidth command. (If a
width is given both in the file and by the set boxwidth command, the one in the file is used.) If the
width is not specified in one of these ways, the width of each box will be calculated automatically so
that it touches the adjacent boxes. relative indicates, that the specified boxwidth is a scaling factor for
the automatically calculated boxwidth, otherwise the boxwidth is taken as an absolute value (which
is the default). In a four-column data set, the fourth column will be interpreted as the box width
unless the width is set to -2.0, in which case the width will be calculated automatically. See set style
boxerrorbars (p. 95) for more details.
To set the box width to automatic use the command
set boxwidth
or, for four-column data,
set boxwidth -2
The same effect can be achieved with the using keyword in plot:
plot ’file’ using 1:2:3:4:(-2)
To set the box width to half of the automatic size use
set boxwidth 0.5 relative
To set the box width to an absolute value of 2 use
set boxwidth 2 absolute
or, if you didn’t specify a relative boxwidth before,
set boxwidth 2
