96 gnuplot 4.0 36 SET-SHOW<br />
To plot a data file with solid filled boxes with a small vertical space separating them (bargraph):<br />
set boxwidth 0.9 relative<br />
set style fill solid 1.0<br />
plot ’file.dat’ with boxes<br />
To plot a sine and a cosine curve in pattern-filled boxes style:<br />
set style fill pattern<br />
plot sin(x) with boxes, cos(x) with boxes<br />
The sin plot will use pattern 0; the cos plot will use pattern 1. Any additional plots would cycle through<br />
the patterns supported by the terminal driver.<br />
To specify explicit fillstyles for each dataset:<br />
plot ’file1’ with boxes fs solid 0.25, \<br />
’file2’ with boxes fs solid 0.50, \<br />
’file3’ with boxes fs solid 0.75, \<br />
’file4’ with boxes fill pattern 1, \<br />
’file5’ with boxes fill empty<br />
Currently only the following terminal drivers support fillstyles other than empty: x11, windows, pm,<br />
postscript, fig, pbm, png, gif, hpdj, hppj, hpljii, hp500c, jpeg, nec cp6, epson 180dpi, epson 60dpi,<br />
epson lx800, okidata, starc and tandy 60dpi. The BeOS driver (be) is untested.<br />
36.57.6.3 Filledcurves The filledcurves style is only relevant to 2-d plotting. It draws either the<br />
current curve closed and filled, or the region between the current curve and a given axis, horizontal or<br />
vertical line, or a point, filled with the current drawing color.<br />
Syntax:<br />
set style [data | function] filledcurves [option]<br />
plot ... with filledcurves [option]<br />
where the option can be<br />
[closed | {x1 | x2 | y1 | y2}[=] | xy=,]<br />
The area is filled between the current curve and<br />
filledcurves closed ... just filled closed curve,<br />
filledcurves x1 ... x1 axis,<br />
filledcurves x2 ... x2 axis, etc for y1 and y2 axes,<br />
filledcurves y1=0 ... line y=0 (at y1 axis) ie parallel to x1 axis,<br />
filledcurves y2=42 ... line y=42 (at y2 axis) ie parallel to x2, etc,<br />
filledcurves xy=10,20 ... point 10,20 of x1,y1 axes (arc-like shape).<br />
Note: filling is supported on filled-polygon capable terminals, see help of set pm3d (p. 82) for their<br />
list.<br />
Zoom of a filled curve drawn from a datafile may produce empty or incorrect area because gnuplot is<br />
clipping points and lines, and not areas.<br />
If the values of , , are out of the drawing boundary, then they are moved to the graph<br />
boundary. Then the actually filled area in the case of option xy=, will depend on xrange and<br />
yrange.<br />
36.57.6.4 Boxxyerrorbars The boxxyerrorbars style is only relevant to 2-d data plotting. It is<br />
a combination of the boxes and xyerrorbars styles.<br />
The box width and height are determined from the x and y errors in the same way as they are for the<br />
xyerrorbars style — either from xlow to xhigh and from ylow to yhigh, or from x-xdelta to x+xdelta<br />
and from y-ydelta to y+ydelta , depending on how many data columns are provided.<br />
If filled-box support is present, then the interior of the boxes is drawn according to the current fillstyle.<br />
See set style fill (p. 93) and boxes (p. 95) for details. Alternatively a new fillstyle may be specified<br />
in the plot command.
