Re: [Gnuplot-info] fence plotting in gnuplot

[pban92 <pb...@ya...>]

@Tait, Thank you for your suggestions! I know what you mean. Now, 

1. Here is the output  http://old.nabble.com/file/p30936652/transp.jpg
transp.jpg  I do not get the transparency effect with,

set style fill  transparent solid 0.50 noborder

2. I liked the cluster histogram but confused about how my data should be
arranged as i did not find immigration.dat file to take a look inside it.

Many thanks!

Re: [Gnuplot-info] Line fitting through the origin

[Thomas S. <t.s...@fz...>]

your line is most likely something like

f(x)=a*x+b

if you want the function to go through 0,0 then
'b' must be zero and 'a' is the only free parameter.

b=0
fit f(x) ... via a

[Gnuplot-info] multiplot - key

[Kai R. <ph...@gm...>]

Hello all,

I am using a multiplot with different functions in the subplots. Now I
am looking for a way to use a single key box that shows all functions in
the subplots. Is that possible?

thanks in advance,

[Gnuplot-info] pm3d map grid question

[Raphael <ro...@cl...>]

Hi all

I have a question regarding to color-map a dataset. Lets say I have 9
datapoints (3x3). If I plot this datafile with pm3d map, than I only get
4 colored boxes (color between the points). Is there a way to get 9
boxes (in such a way that my (x,y)-coordinate is centered in that
colored rectangle and not at the edge?). I have my data like this in the
file :

x1   y1    value
x1   y2    value
x1   y3    value

x2   y1   value
  :
  :

etc

Or do I have to transform my grid my hand?


greetings
Raphael

Re: [Gnuplot-info] explanation to a short script

[Jon <dev...@gm...>]

Dear Tait,

I guess the script you analyzed is what I wrote, but not by Nunzio Losacco.
His code is a bit complex than mine.

What I am asking is basically the concept of one pass or two passes possibly
used by gnuplot, similar concept relevant to SAS or database languages.

Sincerely,
Jon

First, let me answer your question. You can do fence plots by following
the approach in http://gnuplot.sourceforge.net/demo_4.4/surface1.html
(just below halfway down).

However, fence plots are, in my opinion, the wrong solution for your
problem. Because of the pseudo-3D perspective, it is almost imposible to
directly compare the histograms in your second graph. Does "SF4 7a" or
"eSF2 7a" have the higher peak, for example?

Instead, may I suggest you use one of:
- a clustered histogram 
	second plot, http://gnuplot.sourceforge.net/demo_4.4/histograms.html
- a multiplot
	http://t16web.lanl.gov/Kawano/gnuplot/gallery/pressureSlopes.html
- transparency 
	http://gnuplot.sourceforge.net/demo_4.4/transparent.html

Any of these would more clearly present the data and comparison you're
apparently trying to make.

First, are you familiar with C? The syntax is similar, and it is described
in "help ternary". The ternary operator:
	(condition) ? true-expr : false-expr
is a single-line if/then/else construct. If condition is true, then
true-expr is evaluated. Otherwise, false-expr is evaluated instead. So
consider:
	$3<min ? min=$3 : min=min
If the third column is less than the value of the variable min, then
assign this new value to min. Otherwise do a non-operation (of setting
min equal to itself).

The "plot... using ($3<min?min=$3:min=min,$1):3" means plot the third
column as the y-coordinate, against the stuff in parenthesis as the
x-coordinate. In recent gnuplot versions, multiple expressions can
be evaluated for each line of the input file, by separating them with
a comma. The stuff in parenthesis finds the minimum value of column 3
(and saves in it variable min), then evaluates $1, which just means the
value of column 1.

The first plot is output as text in the console, so you might not have
seen it. It doesn't matter, because it's just a throwaway plot used to
find the minimum value of column 3 anyway.

The second plot is the one that matters. It plots your data file using
1:($3/min) which means plot column 3 divided* by min versus column 1.

Another approach to this problem would be to use an external program/script
to find the minimum value of column three. I often use Perl for these
tasks. Others use sed/awk/shell scripts. We should probably develop some
C programs for contrib to do common tasks like this. For example:
	filename="disy.100"
	c3min = `min_value_by_col.pl filename 3`
	set term X11
	plot filename using 1:(($3+0.0)/c3min)




* The division here is possibly integer division, depending on the values
from column 3 of 'disy.100'. If you want to assure floating-point results
from the division, you should instead:
	plot 'disy.100' using 1:((0.0+$3)/min)
or something similar. Adding 0.0 will force promotion of $3 to a float
type, which will in turn force the division to be a floating-point
operation.

Re: [Gnuplot-info] explanation to a short script

[Jon <dev...@gm...>]

Dear Thomas,

I attach the plot here for both cases using the dataset I listed in the
previous email. You can see that the rescaled data really uses 0.1 as the
minimum.

By the way, I cannot understand what you mean by saying "but should be
'0.09', '0.045', and '1'"? Shouldn't the first three be "9,4.5,1", as
correctly shown in the plot I attach in this email?

Thanks,

Sincerely,
Jon

Re: [Gnuplot-info] explanation to a short script

[Thomas S. <t.s...@fz...>]

the script correctly identifies 0.1 as the minimum, yes,
but not for all data points.
you may have noticed that the 1st three y-values in the plot are '1',
but should be '0.09', '0.045', and '1'.

the script searches for the minimum by storing the actual y-value if
it's smaller than a previous one. as long as the absolute minimum
isn't found, i.e. the data line with the minumum y-value hasn't been
yet read, y-values are divided by the intermediate minimum.
that's the reason why the y-values are always '1' when reading
my data set.

[Gnuplot-info] fence plotting in gnuplot

[pban92 <pb...@ya...>]

I am comparing two histograms (red and green) using gnuplot as in here 
http://old.nabble.com/file/p30933874/gnufence0.jpg gnufence0.jpg  but the
red is partially covered by the green. To avoid this overlapping, a fence
plot as shown in here  http://old.nabble.com/file/p30933874/gnufence.jpg
gnufence.jpg  is a good solution undoubtedly. Question is how do I do this
in gnuplot? Suggestions would be highly appreciated. Thanks!

[Gnuplot-info] Latest version of gnuplot

[pban92 <pb...@ya...>]

This is my version which I thought looking at the version number 4.5 to be
the latest one. 

        G N U P L O T
        Version 4.5 patchlevel 0
        last modified November 2009
        System: MS-Windows 32 bit

But here  http://www.gnuplot.info/download.html
http://www.gnuplot.info/download.html  it says "The release of version 4.4.0
was announced on March 13, 2010". 

So which is the latest one? 
Many thanks!

Re: [Gnuplot-info] explanation to a short script

[Jon <dev...@gm...>]

Dear Thomas,

I actually specifically checked whether the first script could capture a
minimum hidden in the data except for the first line. The sample data I used
is

1  0.9
2  0.45
3  0.1
4  0.94
5  0.44
6  0.12
7  0.36

and it seems a single pass corrected identified 0.1 as the minimum. As to
your sample data, the missing of y range is a 2nd mysterious to me as if I
change the data to float, it works fine, and even if I interpret the data to
be integer, it should still give the right answer instead of giving constant
1 for each dataline.

Sincerely,
Jon

Re: [Gnuplot-info] explanation to a short script

[Thomas S. <t.s...@fz...>]

strictly  speaking, nunzio's script only works if the smallest number is in
the
1st data line.

an example:

#ts.dat:
1 10
2 9
3 8
4 7
5 6
6 5
7 4
8 3
9 2
10 1

#script:
min=10**10
grab(x)=x<min?min=x:min=min
plot 'ts.dat' using 1:($2/grab($2))

gives a horizontal line and a warning about the empty y-range.
this means that gnuplot behaves like other programming languages
and there is no magic behind it.

a 2nd plot gives the correct result, as you have pointed out,
because then 'min' already contains the smallest value.

#script:
min=10**10
grab(x)=x<min?min=x:min=min
plot "ts.dat" using 1:($2/grab($2)), "" using 1:($2/grab($2))

... , "" using 1:($2/grab($2))
is equivalent to
... , "" using 1:($2/min)

[Gnuplot-info] explanation to a short script

[Jon <dev...@gm...>]

Dear Thomas,

Nunzio Losacco wrote a short script to get each number divided by the
smallest number in a specific column, as
min=10**10
grab(x)=x<min?min=x:min=min
plot 'disy.100' u 1:($3/grab($3))

I don't quite understand the logic behind although I checked that it works
fine. If I were to do this, I would write something like

set term dumb
min=10**10
plot 'disy.100' u ($3<min?min=$3:min=min,$1):3

set term x11
plot 'disy.100' u 1:($3/min)

and you easily see the idea I wrote it this way. I think this reflects a big
problem for me to understand deeply how gnuplot deals with datafile and how
it plots, which is obviously different from the standard programming
languages. Thanks for your in-depth explanation or references,

Sincerely,
Jon

[Gnuplot-info] Recognize end-of-file in iterations

[Nunzio L. <nun...@gm...>]

Hi all,

I have some datafiles all named disy.100 in different directories and I want
to plot them all using column 1 vs 3 the latter being divided for the
minimum value in each datafile.

After googleing a bit, for a single file I managed to do:

min=10**10
grab(x)=x<min?min=x:min=min
plot 'disy.100' u 1:($3/grab($3))

and that's fine.

Now I want to do it iteratively starting from the parent directory:

list=system("ls")
min=10**10
grab(x)=x<min?min=x:min=min
plot for[i in list] i.'/disy.100' u 1:($3/grab($3))

but in this case min gets the minimum value of columns 3 of ALL datafiles to
be plotted, while I want it to be the minimum for each dataset.
Do you have any suggestions for doing that other than processing the files
through awk first?

Thanks for your help!

[Gnuplot-info] Crashes in Gnuplot

[MortenMacFly <ma...@gm...>]

Dear all,
I actually just realised that Gnuplot also has a mailing list. :-)
Please allow me a general question: What is the preferred way to inform
about bugs? I've posted a bug on the bugtracker
(http://sourceforge.net/tracker/?func=detail&atid=102055&aid=3177173&group_id=2055),
but see a lot of recent discussion here. Is the bugtracker still
appropriate?

Re: [Gnuplot-info] re ad a datafile into an array, is it possible?

[Thomas S. <t.s...@fz...>]

sorry, yes, i meant 'stringcolumn(0)'

'stringcolumn(0)' isn't working in gnuplot version 4.4
- here we have to use the sprintf() -,
but in the development version 4.5 it is.

Re: [Gnuplot-info] re ad a datafile into an array, is it possible?

[Jon <dev...@gm...>]

Dear Thomas,

I tested the command you suggested, but gnuplot complains that columnstring
command not found, so I changed to stringcolumn command, but it still
complains that

"combined_plot_1.gu", line 8: x range is invalid

but if I change all stringcolumn(0) as stringcolumn(1), then at least it
works. So it seems to me that stringcolumn(0) cannot be corrected executed.
Am I right?

Meanwhile, I think of the following as alternative

p 'aaa.txt' u (cc=sprintf("%i",column(0)), \
                   vs=vs.'; v'.cc.'='.stringcolumn(1), \
                   ws=ws.'; w'.cc.'='.stringcolumn(2), \
                   $1):2 )

but still it is not as elegant as your previous suggestion, so I hope your
advice could work out.

Sincerely,
Jon

Re: [Gnuplot-info] candlesticks / whiskerbars in clusters

[Thomas S. <t.s...@fz...>]

plot normal candlesticks and do the clustering by shifting the x-values:

datafile.dat:

5 2 1 4 3 5 4 8 6 4 3 6 5
6 5 4 8 6 4 3 6 5 2 1 4 3
7 4 3 6 5 2 1 4 3 5 4 8 6
8 2 1 4 3 5 4 8 6 4 3 6 5

plot commands:

set xrange [4:9]
set yrange [0:9]
set boxwidth 0.1
plot "datafile.dat" using ($1-0.15):2:3:4:5 with candlesticks whiskerbars, \
"" using 1:6:7:8:9:xtic(1) with candlesticks whiskerbars, \
"" using ($1+0.15):10:11:12:13 with candlesticks whiskerbars

[Gnuplot-info] candlesticks / whiskerbars in clusters

[Simon F. <S.F...@su...>]

hi all,

Please can you help?
I am trying to form clusters - like this example, http://www.codealias.info/technotes/gnuplot_cluster_histogram_example
...but with candlesticks and whiskerbars!

Is this possible, can anyone help me achieve this result? I am also defining the set of xtics names corresponding to values in datafiles

Any help/advice appreciated
all the best
simon

Re: [Gnuplot-info] Plot a function in defined intervall

[Jon <dev...@gm...>]

The version I used is

Version 4.4 patchlevel 2

and I run help plot under entering gnuplot,

Still, is it possible to rearrange the help files so that it could be easier
for new-comers to locate specific items to help?

Thanks,

Sincerely,
Jon
