Thanks Thomas,

I wasn't aware of the possibility of running commands and using their
output as "files". Very nice!

Thanks again for your help,

nick

plot "< join file1.dat file2.dat" using 1:($2+$3) with linespoints

if 'file1.dat' has more than 2 entries per line you need to increase
the '$3' in the 'using' option.

the 'join' command is in the 'gnu coreutils' which are normally
installed on every linux-system, for windows you need to
install it (search for 'GnuWin').

Hello list,

is it possible to combine data from different files in one plot
statement? I am looking for something like this:

plot using column(1,file1.dat):(column(2,file1.dat)+column(2,file2.dat))
with linespoints

Thanks already,

1. what do you mean by 'ladder graph'? there are several different
graphs when searching for 'ladder graph' with google (images).

2. do you work with a data file? if yes, how does it look like?

Hi 

This is first time for me using gnuplot. Last week I tried to draw ladder graph with excell and other tool but not work. 
So, I'd like to know how to draw a ladder graph with gnuplot?

Thank you in advance. 
Cooky

a little bit simpler:

p [0.85:6.5] [0:1.2] 1/x,'-' using 1:(1./$1) with points
1
2
3
4
5
6
e

or a little bit more difficult:

set xrange [1:4]
set samples 4
set table 'temp.dat'
plot 1./x
unset table
set xrange [0.85:6.5] 
set yrange [0:1.2]
set samples 100
plot 1./x, 'temp.dat' with points

Thanks, really wonderful!

I did something like this, (of course very awkward one)

p [0.85:6.5] [0:1.2] 1/x,'-' w p
1 1
2 0.5
3 0.333
4 0.25
5 0.2
6 0.166

just to share with others ..

if the y-values can be described using a function (like in your example):

set samples 4
f(x)=1./x
set xrange [1:4]
plot f(x) with linespoints

Hi,

I would like to draw a very simple plot composed of a list of disconnected
points, I am wondering whether there is anything like

plot {1,2,3,4} {1/1,1/2,1/3,1/4}

where the first list is for x while the second list is for y.

What I know to plot this is to set up a file containing two columns, but to
such a simple plot, I hope there were more straightforward ways

Thanks,

Sincerely,
Jon

you could cut the first word (the line number) using awk:

history 10 '| head -5 | awk "{for(i=2; i<NF; i++) {printf(\"%s \", \$i)} ;
print \$NF}" > diary.gp'

Hi all,

I'm using Gnuplot development version 4.5. However I try I cannot make the
"history" command behave as I wish.

All history commands seem to yield the history command itself as the last
issued command (sorry for the tongue-twister).
This is a bit annoying as commands like:

history [n] "filename"

will write the last n commands PLUS the command 'history [n] "filename" ' to
file filename. So doing  load 'filename' will also execute the latter,
meaning that the file itself will change.

history 10 "|head -5 >>diary.gp"

behaves almost fine apart writing the command number at the beginning of
each line, which makes file "diary,gp" useless.

There's no way to combine the "quite" option and write to a file.

Are this behaviours normal or should they be considered bugs?

Regards,

N.

you could use the special filename "+" and the ternary operator

set xrange [-2:1]
plot '+' using ($1>=0.0?$1:0/0):(sin($1))

Hello list,

I have a data set that I fit a function to. Suppose now that I want to
limit the range this function is plotted to something less than the
xrange I am using, i.e. can I specify a separate xrange for the
function than what I am using for the data?

Hi Gnuplot,

  How I can get the mouse coordinate in 3D via a splot command. I use splot
command to show a curved surface in 3D. I want to get some point coordinate
(x,y,z) when I point these points via the mouse on the showed surface. Since
each point of the surface map only one coordinate (x,y,z), it should be a
way to get the mouse coordinate when the mouse point to a dot on the screen.

OK I worked it out and the syntax is clear. 
The mistake was not as I thought but something else.

Many thanks for your whole lot of helps.

@Tait,

Ok I see the mistake. I used 1/1500000 instead of 1.0/1500000. Having said
that I surely did not understand the syntax. Why did it differ? Is that sort
of truncation error related to integer/real number? 

Many thanks for the clarification!

Thanks Tait, I tried that but it did not work and hence the post.

Does it work to do something as simple as:
	... using (bin($1,binwidth)):(1.0/1500000) ...

Hi All,

This histogram  http://old.nabble.com/file/p30953313/hist1.jpg hist1.jpg 
was created by,

clear
set style fill solid 1.0 border -1  
set style fill  transparent solid 0.50 noborder
binwidth=0.01
bin(x,width)=width*floor(x/width) + binwidth/2.0
plot 'case769.nvd' u (bin($1,binwidth)):(1.0) t 's2c' smooth freq w boxes,\
'case001.nvd' u (bin($1,binwidth)):(1.0) t 's2f0' smooth freq w boxes,\
'case481.nvd' u (bin($1,binwidth)):(1.0) t 's2f1' smooth freq w boxes,\
'case577.nvd' u (bin($1,binwidth)):(1.0) t 's2f2' smooth freq w boxes,\
'case673.nvd' u (bin($1,binwidth)):(1.0) t 's2f3' smooth freq w boxes

But I intend to divide the y-axis range by 1500000 to give y-axis look like
this  http://old.nabble.com/file/p30953313/hist2.jpg hist2.jpg  . 
Could anybody suggest how to do it? Many thanks in advance for your answer.

It's probably not reasonable to ask gnuplot to draw 1.5 million tic
marks (the using with xtic(1)). So don't do that. Instead, only draw
every 150000th xtic or so, using every. Something like:

plot 'set1st01.txt' using 1, '' using 2, '' using 3, '' using 4, '' using 5, '' using (0):xtic(1) every 150000 notitle

The last plot item just plots the constant value 0, and creates a tic
mark, every 10000th row. See "help every" for the complete syntax.

As for a built-in way to do fence plots, there is only the link I gave
originally, using parametric mode.

@Tait, I really appreciate your continuous help.
1. The transparency problem was solved after I got the latest version.
2. For the cluster, it seems the following code is correct as it gave no
error but the never ending execution of the graph is taking ages forcing me
to quit. Is my code wrong? My text file has five columns with 1.5 million
rows. 

clear
set boxwidth 0.75 absolute
set style fill solid 1.00 border -1
set style data histogram
set style histogram cluster gap 1
plot 'set1st01.txt' using 1, '' using 2, '' using 3, '' using 4, '' using
5:xtic(1) 

3. Referring to OP, is there any built in gnuplot built in function for
waterfall/fence plotting?

The set style fill syntax you have ought to work. It did for me. Perhaps
the particular flavor of JPG terminal that you're using doesn't support
it? (That seems unlikely, as I think both libgd and Cairo support
transparency.) Transparency support wasn't present pre-4.4, but then you
should have gotten an error on the set command.

The files for all the demos are in the demo directory of your gnuplot
installation. Normally they'd also be available to in the SourceForge
CVS file browser, but that is down now because of the attacks.

Histograms are a 1-D plot type, so I'm not sure how/if it will work with
smoothing. You might have to do the frequency smoothing in one pass to
generate a data table (help table), and then plot the frequency-smoothed
data file as a histogram using 2:xticlabels(1) or something similar.

In case you can't find it, here is the first few columns of
immigration.dat:
	# IMMIGRATION BY REGION AND SELECTED COUNTRY OF LAST RESIDENCE
	#
	Region	Austria	Hungary	Belgium	Czechoslovakia	...etc
	1891-1900	234081	181288	18167	-
	1901-1910	668209	808511	41635	-
	1911-1920	453649	442693	33746	3426
	1921-1930	32868	30680	15846	102194
	1931-1940	3563	7861	4817	14393
	1941-1950	24860	3469	12189	8347
	1951-1960	67106	36637	18575	918
	1961-1970	20621	5401	9192	3273
