FW: Gnuplot in ubuntu

2008-07-23T22:52:21Z

Hi,

I just installed gnuplot in ubuntu 7.10 i didn't have any problem with the install but when I try to use the png terminal I cannot do it.

Does anybody knows why? maybe I don’t have the library to use the png.

Please help me

Thanks

hi,

Thank you for the quick response.. my terminal type is postscript. But I don't understand how should i use secondary y-axes??

Thanking you,

Multiplot is almost never the right technique for that kind of job.
Secondary y axes would be a lot easier to use.

Nitpick: "enhanced" is not a terminal type. It's a common terminal
option. What actually was your terminal type?

Read "help enhanced" again, slowly. Find the '~' and learn what you
just did, and how not to do it.

Ebhanced terminal type with Multiplot error

2008-07-23T09:25:26Z

hi,

This is Suman from Univ of Miami .. I have been Gnuplot since 2 years now. It's just great to use. But right now, I am need to combine two plots together whose x-coordinate scale factor is the same but not the y-coordinate. I used the multiplot command to do this and since I needed to change the font also for some labels and titles, I used the enhanced terminal type. Now I want to put a label as "~" at the end points of the two figures separating y-scales(or we can say between the two figures on the y-axis) to show the change of scale but I am not able to do so. When I do not use the terminal type "enhanced", the "~" label works but when I use it along with this terminal, I don't see my figures at all except the lower figures bounding box and the x and y scales .. I believe there is some font problem probably but I do not know what exactly it it. So please can you help me in this?? I will be very thankful to you.

Suman

Plottin 3D with one column

2008-07-22T18:46:39Z

I was thinking of creating a 3D surface with 9 regions that will be based on just one column. So, 1 entry in the column will correspond to 1 region on the surface wherein the intensity/amplitude/level will depend on the given value. I hope you guys could help me out Thanks, Bryan

No. There's no promise of the range reversal affecting sampling order.
It affects the relation between coordinates and positions on a graph,
not the order in which those positions are visited. That ordering is
generally unimportant, since you couldn't spot the difference in the
resulting image anyway.

The table driver makes that a bit mor complicated, of course. But, like
with so many problems, parametric mode helps:

Option reverse and table

2008-07-22T14:25:17Z

Hello everyone

I have to use table terminal mode to recover the coordinates from a
plotted function with decreasing X.

Example: I want to plot the function f(x)=x^2 between 0 and 10
I want the coordinates from x=10 to x=0

------------------------------------
The commands I wrote:

set table "out"
set xrange [0:10] reverse
plot x**2
------------------------

Then I edit the file called "out"
but the first lines are:

0 0 i
0.10101 0.010203 i
0.20202 0.0408122 i
0.30303 0.0918274 i
0.40404 0.163249 i
0.505051 0.255076 i
0.606061 0.367309 i
0.707071 0.499949 i
0.808081 0.652995 i
0.909091 0.826446 i
1.0101 1.0203 i
..............
Hence, x are in increasing mode, and not decreasing as I wish.

Is it a bug ? If it isn't, how can I release what I want?
Thanks in advance

Best regards

Loïc

Histograms

2008-07-21T14:30:57Z

Hi,

I am a beginner with gnuplot
I try to draw in the same figure two histograms from different data files.
I did this:

plot [-1:5] 'file1' using 1
with boxes,'file2' with boxes

The problem is that I get the boxes for the first file , however i get vetival lines for the second file.
Any idea???
And I want to used different line types for each histogram, how can I do??
Thanks in advance

Re: heatmap + ternary operator problem

2008-07-21T11:28:36Z

Thanks, after some further research I came to the same conclusion...

> set pal mod RGB funct (gray>1./400.?sqrt(gray):1), (gray>1./400.?gray**3:1), (gray>1./400.?sin(gray*2.*pi):1)

This is quite fancy! Amazing...
by now I changed the coloring to a simple gradient: white,purple,blue,cyan,green,yellow,red
Which also works - if not as sophisticated...

Many thanks,
Thomas

for each grid point a value is required, so exclusion is not possible.

make the unwanted points white:

set pal mod RGB funct (gray>1./400.?sqrt(gray):1), (gray>1./400.?gray**3:1), (gray>1./400.?sin(gray*2.*pi):1)

(you may replace 1./400. by some value smaller than your valid data)

heatmap + ternary operator problem

2008-07-21T02:57:29Z

Maybe I don't understand the syntax right, but in priciple I get the plot to work when I do

$ set view map
$ set xrange [60:200]
$ set yrange [0:300]
$ set cbrange [0:200]
$ splot "radET1.hdat" u 1:2:4 w image

This gives me a projection of my data to the xy-plane. Now, what I like to do is to exclude points in column 4 which are zero, since in my plot they have no physical meaning and should not be included in the pm3d coloring. Therefore I thought something like

$ splot "radET1.hdat" u 1:2:( $4==0 ? 1/0 : 4 ) w image

would do the trick, but doesn't. It always gives errors like
"GNUPLOT (plot_image): Image grid must be at least 2 x 2" or
"GNUPLOT (plot_image): Visible pixel grid has a scan line shorter than previous scan lines"

Mabe it isn't even possible to exclude points from grid data like this? Any clues??
(For now I shifted the cbrange sightly to negative values)
Thanks in advance,
Thomas

you don't need to (i just found out how it works):
there is the 'noenhanced' option for 'set xlabel' (and other labels)
which switches the enhanced mode off for this label.
it's useful for labels which contain no special 'enhanced' sequences.

just append 'noenhanced' to your 'set xlabel' command and the xlabel
will appear at the same position as it would appear in 'noenhanced'
mode.

it's the 'enhanced' option which positions the xlabel at a slightly
different position than 'noenhanced' mode does.
the bounding box should be adjusted differently in 'enhanced' mode,
but it isn't.

Many thanks, Thomas, this works! I reset the bounding box with pico. Is it possible to make it via gnuplot? Or is it better to write a little script to change the bounding boxes in all of my figures? I have a lot. :-) And I've never did such a thing. . .

Thanks again for your help.

it's the 'enhanced' option which positions the xlabel at a slightly
different position than 'noenhanced' mode does.
the bounding box should be adjusted differently in 'enhanced' mode,
but it isn't.

you could adjust (with a simple text editor) the bounding box from
%%BoundingBox: 50 50 410 302
to
%%BoundingBox: 50 48 410 302
in the eps-file to get the complete xlabel shown.

set label 1 "abc" at graph 0.5,0.95 center

will place your label centered in the middle of the x axis just below the
upper y axis.

Re: Gnuplot updating graphs in real time

2008-07-17T08:03:54Z

Thank you very much Thomas. So one more question about the labels.
How can I set the label to display in the same position, i.e. Top of graph if the graph starts with y values from 0 to 2, but later a value pops in to say 50? If i set it using coordinates, then the whole scale changes, the position of the labels change. Basically I'd like to create a fixed label...

a 'show label' will tell you that you have defined a whole bunch of labels,
because each 'set label' creates a new label.
but - each label has also a tag (see 'help label')!

so, modifying your script so that your labels have defined tags
will result in modified labels:

set label 1 'Packet Count: $total_packets' at 1,1;
set label 2 'Total Retransmits: $total_retrans' at 1,1.5;

I tried out many methods to avoid this problem, but I failed. When I draw an eps file via gnuplot with an x label in the figure, it always cuts down the bottom of the letters that are in the label. For example, if I write into the scripit: set xlabel "gravity" . . . it will cut down the bottom of g and y. Does anyone has a suggestion to avoid this?

Thank you very much in advance!

Kind regards,
Agoniabogar

a 'show label' will tell you that you have defined a whole bunch of labels,
because each 'set label' creates a new label.
but - each label has also a tag (see 'help label')!

so, modifying your script so that your labels have defined tags
will result in modified labels:

set label 1 'Packet Count: $total_packets' at 1,1;
set label 2 'Total Retransmits: $total_retrans' at 1,1.5;

Gnuplot updating graphs in real time

2008-07-16T12:59:48Z

Hi all I have a perl script that is updating my graph in real time.

Basically I am graphing retransmitted packets from netstat -s counter data

Everything is working pretty good, but I thought it would be nice if I could print out the total Retransmits seen as well as the total packets seen.

I can get that to work too, but unfortunately as soon as the data is updated the numbers garble up as they aren't clearing the previous numbers, but are overwriting them. I am doing this by passing the variable for total packets to the label paramter in gnuplot...

Does anyone have any idea of a way to get gnuplot to print a constantly changing number somewhere on the graph, or is this beyond its capabilities?

Here is the basic gnuplot syntax I'm using from within my perl script... This is all on one line in the script, but I'm breaking it out to make it a bit more readable.

print GP "
set term x11;
set style data line;
set title 'Retransmits';set xlabel 'Time';
set yrange [0 : ];
set label 'Packet Count: $total_packets' at 1,1;
set label 'Total Retransmits: $total_retrans' at 1,1.5;
plot '/tmp/retransmit.dat.$file_date' \n";

But unlike pwd and cd, which are needed for gnuplot's own operation (the
current directory directory directly affects file lookup), 'ls' doesn't
do anything for gnuplot. It would therefore go directly against the
Unix tool philosophy of "one tool <-> one task". Because of this, I'm
opposed to this change.

See "help loadpath".

How can I run an Executable file programmatically with PHP

2008-07-14T15:15:13Z

Dear All,

I am running an NSGA-II optimisation code with GNUPlot. I can run it successfully within linux command prompt with './nsga2r 0.64 < [input_file]' but I could not get the output when I run this command within a php program. My php code is:

<?php
$makeclean =shell_exec('make clean');
$make=shell_exec('make');
$nsga2_optimisation_result = passthru('./nsga2r 0.123 < weldede_beam_inputs.in');
echo "<pre>$makeclean</pre>";
echo "<pre>$make</pre>";
echo "<pre>$nsga2_optimisation_result</pre>";
?>

The NSGA-II code is found at: http://www.iitk.ac.in/kangal/codes.shtml and the flavour Iam using is: Revision 1.1 (10 June 2005) (for Linux only): NSGA-II in C with gnuplot (Real + Binary + Constraint Handling).

Please how can I run a program (witten in c) that has gnuplot and get the output on a web browser using php.

Any help is appreciated
Kind regards
Gokop

win32 build of wxt terminal?

2008-07-12T09:17:44Z

Hello all,

I was wondering if there are any win32 builds of gnuplot that include
wxt terminal support?

I've tried the latest binary snapshots of 4.3. Is the wxt terminal
supported in win32 builds?

Thanks,
Gary.

Projection

2008-07-10T07:46:17Z

I would like to know if it is possible, to do a 2D projection of 3D diagram in a 2D plot.

By now I only was able to do a 3D plot, unset the surface and rotate the view so it looks like a 2D projection...

You can use a function of your choice to map the fitted parameter to the
one used in the function, e.g.

a(a_fit) = exp(a_fit)
# or
# a(a_fit) = 2+tanh(a_fit)/2

fit f(x,a(a_fit)) 'data' via a_fit

Re: UTF-8 encoding

2008-07-02T20:02:43Z

Dear Robert,
you have to use gnuplot 4.3 from CVS in order to make this work (if there is a
precompiled M$-binary, what I do not know).
The only other alternative for now is opensuse 11.0 because the version of
gnuplot that is shipped with it has been patched to work as you'd expect it
to.
Hope this helps
take care

UTF-8 encoding

2008-07-02T03:43:34Z

Hi all,

I'm using gnuplot 4.2 on Windows XP. What I want to do is to plot from a file
containing IPA symbols encoded in UTF-8. However, if I do

set terminal png font arialuni
plot 'file' using 2:3:1 with labels

the correct font is used, but the UTF-8 file seems to be interpreted as ISO-
Latin-1 or whatever the default setting is (e.g. inverted e's turn to an
accented E). I tried to do

set encoding utf8

but I was told by the terminal that it was

expecting one of 'default', 'iso_8859_1', 'iso_8859_2', 'iso_8859_15',
'cp437', 'cp850', 'cp852', 'koi8r', 'koi8u'

Is there any way to add UTF-8? Or any other way to get my IPA symbols onto the
plot?

Robert

The attached patch achieves the speedup and works
properly with mousevariables.dem.

The use of __CYGWIN__ makes it specific to that platform.

I suspect this would also help other platforms.

Please consider for upstream inclusion.

and I want to make a plot where point (x,y,z) gets a color depending on the value of t. Anyone knows how to do that?
