I spent some time last night learning how to hack your code to do mostly what I want. GRI seems to be a very powerful and useful tool! Now could you please suggest how I could get it to display a block of each color followed by the label for it at the top right corner of the graph... I'm sure I can work this out given enough time, but the presentation is in 4 hours time... What I want to do is have the labels at the bottom attach to groups of 3 or 4 columns. For each group have 3 or 4 colors used. Each group will compare the performance of different file systems for a particular test. Russell Coker -- Electronic information tampers with your soul.

Well, I'm not claiming the stuff below is good:). But is is
easy, and you can generate it from a makefile (just make the
makefile insert your own table where I now got that postscript

Nice PS, Joost!
Folks, don't forget the power of PIC. It's sitting there as part
of groff.
Example: make a file called barchart with the following contents:
8--- cut here -
.LP
.PS
vscale = 4
define bar {
x = $1
y1 = $2/vscale
ylabel = $2
line from x,0 to (x+0.25),0 to (x+0.25),y1
line from (x+0.25),y1 to (x-0.25),y1 sprintf(%0.2f,ylabel) above
line from (x-0.25),y1 to (x-0.25),0 to x,0
line from (x-0.2,-0.2) to (x,0) invis $3 rjust aligned
}
define barchart {
i=i+1
y = $2
bar(i,y,$1)
}
i=0
copy bar.dat thru barchart
.PE
8--- cut here -
and a data file called bar.dat with contents:
8--- cut here -
widget 15.0
bidget 13.5
squidget 18.0
midget 5
didget 10.2
8--- cut here -
Then run
groff -Tps -p -ms barchart barchart.ps
and see what you get. (One advantage of doing it this kind of way
is that it's much easier to add complications to the figure using
PIC than it is by modifying PostScript such as Joost's).
Best wishes,
Ted.

Ok, here's my shoot at it using `gri'
http://www.debian.org/Packages/unstable/math/gri.html
http://www.phys.ocean.dal.ca/~kelley/gri/
(See http://www.debian.org/~psg for a pointer to a slink version)
Note that gri, like gnuplot I assume, doesn't have the concept of a
bar chart. Yet you can easily program it to do what you want (and
further customize fonts, line widths, colours, etc)
Assume the two data files:
--- bar.dat ---
15
13.5
18
5
10.2
--- bar.dat ---
--- bar.labels ---
widget
bidget
squidget
midget
didget
--- bar.labels ---
Run the following bar.gri file like so:
$ gri bar.gri
to produce bar.ps
--- bar.gri ---
set x margin 5
set y margin 8
set x axis 0 10
set y axis 0 20
set x size 10
set y size 15
.xLeft. = 1
.toggle. = 0
open bar.dat
open bar.labels
while 1
read from bar.labels
read \label
if ..eof..
break
end if
read from bar.dat
read .val.
set color hsb {rpn .xLeft. 1 - 6 /} 1 1
draw box filled .xLeft. 0 {rpn .xLeft. .9 +} .val.
set color black
draw box.xLeft. 0 {rpn .xLeft. .9 +} .val.
sprintf \.val. %.1lf .val.
draw label \.val. centered at \
{rpn .xLeft. .45 + xusertocm} \
{rpn .val. yusertocm .2 +} cm
if .toggle.
draw label \label centered at \
{rpn .xLeft. .45 + xusertocm} \
{rpn ..ymargin.. .7 -} cm
.toggle. = 0
else
draw label \label centered at \
{rpn .xLeft. .45 + xusertocm} \
{rpn ..ymargin.. 1.2 -} cm
.toggle. = 1
end if
.xLeft. += 1
end while

Hi! I'd like to know if there is any good free application for preparing of presentation graphics available in Debian distribution. Such functions as bar charts, pie charts, scatter plots, line charts, whisker box (for presentation os standard deviation) and so on are necessary. I'm just preparing small presentation about application of Linux in digital signal processing. I wouldn't like to have to present transparencies prepared with M$ PowerPoint... If someone knows about such package, or could suggest another solution (maybe a set of macros for Scilab, or Latex???) - please let me know.

(maybe a set of macros for Scilab, or Latex???) - please let me know.
The program you are looking for is gnuplot. If you use latex, there are
even some features to include the results in a latex file. Here's a quick
start (since it took me way to long to figure this out):
[ Note, file.dat is usually 2 points on each line. I haven't tried the 3d
stuff yet. ]
1) gnuplot - takes yo into an interactive mode to do the following
2) plot 'file1.dat', 'file2.dat' with style num
where style can be any of the following:
`lines`, `points`, `linespoints`, `impulses`, `dots`, `steps`,
`fsteps`, `histeps`, `errorbars`, `xerrorbars`, `yerrorbars`,
`xyerrorbars`, `boxes`, `boxerrorbars`, `boxxyerrorbars`,
`financebars`, `candlesticks` or `vector`
and num effects the color
For latex:
3) set terminal latex- make latex compatable output
4) set output 'filename.tex' - don't make the visual plot
5) plot ... - send stuff to the file
6) In latex, use: \input{filename}
HTH,
Brandon
P.S. gnuplot has excellent online help, type 'help' at the prompt to step
through everything.
