Re: [Gnuplot-info] Errorbars not showing if specified as time/date data

[thse <t.s...@fz...>]

the y-values are interpreted according to what has been set
in 'set timefmt', the delta-y-values not.

the easiest way is to give the delta-y-data in seconds:

1 00:02:16 52
2 00:02:14 120
3 00:02:01 52
4 00:01:58 52
5 00:01:45 52
6 00:01:32 61
7 00:01:32 52
8 00:01:22 52
9 00:01:17 52

that was my point:

1) this script shows *no* errobars, whereas it should:

2) this script shows errobars correctly, as expected:

3) this script (correctly) shows the errorbars if these are specified

Should it, now?  How do you figure that column three of these two data

would both parse successfully, with the same input specification?

[Gnuplot-info] Errorbars not showing if specified as time/date data

Hi,

I am using gnuplot 4.4 patchlevel 4 (compied via homebrew) on Mac OS X
10.7.5 (GCC 4.2.1).

The following snippet should produce a series of points, all with
their errobars. However, this is the output that it produces instead:

Am I missing something?

[Clement L. <the...@gm...>]

Hello,

I did this yesterday, in fact.

In gnuplot, issue:

plot "< sort -kn3nr datafile" u 1:3 w lp

This should be roughly what you want.

Re: [Gnuplot-info] How to directly sort data and plot

[Jian-Ming Z. <jm...@gm...>]

Hi,

Thanks for the reply. I have tried "smooth unique," but it did not work for me.

For example, the data file is shown as follow.
1 10
2 15
3 1
4 15
5 30
I want plot column 2 as y values in order of the values. That is, the
first y value is 30, the second y value is 15, the third value is 15,
and so on. I can do so by sorting the file by column 2. The file is
sorted as follows.
5 30
2 15
4 15
1 10
3 1

Then I plot the sorted file by using: plot 'datafile' using 2 w linespoints

Please kindly let me know how to use "smooth unique" to do so. Thanks.

[Gnuplot-info] How to directly sort data and plot

[Jian-Ming Z. <jm...@gm...>]

Hi,

I have a data file which contains several columns. The data in the
file are not sorted. I want to sort the data of a column (for example,
column 3) and plot the data. I use UNIX command sort to sort the data
and then use gnuplot to plot the data.

$ sort -k3nr datafile > sortfile     # sort column 3 in decreasing order
gnuplot> plot 'sortfile' u 3 w linespoints     # plot sorted values of
column 3 at x = 0, 1, 2, …

Is it possible to directly sort the data and plot the results in
gnuplot? If yes, how to do it?

Thanks

[Gnuplot-info] How to plot data at the specified x values when data file has y values

[Jian-Ming Z. <jm...@gm...>]

Hi,

I have several data files which contain only one column (y values) as
follows.
162
144
140
122
…

I plot the first column in the files as y values by using the command:
plot "datafile" using 1 with linespoints

The data will be plotted along the x axis at 0, 1, 2, …

However, I want to show that the first data is at x = 100, the second data
is at x = 200 and so on. If the data file contains two columns for the x
values and y values, it should be
100 162
200 144
300 140
400 122
…
and the command is: plot "datafile" using 1:2 with linespoints

I don't want to modify my data files to contain two columns. I have tried
"set xtics 100, 100" but it did now work as expected.

How can I plot data with the specified x values when the data file has only
one column for y values?

Thanks.

ps. I can use another file which contains the x values if needed.

Not quite the same thing.
Adding minor tics on the r axis was trivial;  it only required adding the r axis to the set of existing axes to which minor tic processing is applied.  But there is no "theta" axis, and no data structures are maintained to describe it.   So introducing commands that refer to theta would involve writing new code and adding new data structures to support it.

Re: [Gnuplot-info] mrtics?

[Tom L. <tl...@cp...>]

Awesome, thankyou!

Following on from that....:

Also, as I'm coding a (LabVIEW) wrapper for gnuplot, it strikes me polar plots would have a flatter syntax, more closely related to X-Y plots, if there were "thetatics" and "mthetatics", such that "set grid polar" could follow similar syntax to XY plots, without the currently required exception of passing the radial tic spacing....

So instead of:
set grid polar 45

there [w|c]ould be:
set thetatics 45
set mthetatics 3
set rics 0,1,10
set mrtics 2
set grid polar thetatics mthetatics rtics nomrtics

-wordier, but flatter, and more flexible....?

I'm afraid, as a LabVIEW programmer, I'm in no position to submit a patch, just this feature suggestion/ request...

Thanks for your consideration,

Tom

[Gnuplot-info] mrtics?

Am I missing something, or is there no polar plot equivalent for "mytics"- minor tics on the ordinate axis? I'd expect these to be "mrtics"...

Many thanks,

[Gnuplot-info] How can I coloured a region bounded by functions?

[tobal <lop...@gm...>]

Hi! I'm plotting an optimization problem and i want to fill the bounded
region (polygon) between restrictions but i don't know how to make it, I've
seen this link http://gnuplot.sourceforge.net/demo_svg/fillbetween.html but
I don't understand anything. The code is this one:

set style fill solid 1.0
set title 'Problema de Optimizacion'
set multiplot
set border 3
set xtics nomirror
set ytics nomirror
set parametric
const1=300
const2=0
set trange [0:450]
set xrange [0:500]
set yrange [0:500]
set size ratio 1.0
plot const1,t title 'x = 300',const2,t title 'x = 0' lw 4
unset parametric
set key left top
plot 400 title 'y = 400' lc rgb 'blue',\
 500-x title 'y=500-x' lc rgb 'brown', 0 title 'y=0' lc rgb 'orange' lw 4
set nomultiplot
pause -1

And I want to colour the region that i indicate at the next image:

<http://gnuplot.10905.n7.nabble.com/file/n17581/programacionlineal.png> 

The mathematical problem is this one:

f(x,y)=450y+600x

s.a.
y<=400
x<=300
y+x<=500
y>=0
x>=0

Thanks

[Gnuplot-info] Histogram title rotation

[Dominik E. <dom...@gm...>]

Hi list,

I use some newhistogram plotting constructs like in
http://gnuplot.sourceforge.net/docs_4.2/node250.html

     set style histogram  cluster
     plot newhistogram "Set A", 'a' using 1, '' using 2, '' using 3, \
          newhistogram "Set B", 'b' using 1, '' using 2, '' using 3

The question is: how can I rotate the newhistogram titles, i.e. "Set
A" and "Set B" in the example above?

Thanks
Dominik

[Gnuplot-info] Thanks for gnuplot, plus an animation

[Keith L. <ke...@ga...>]

Hey folks!  I've been using/abusing gnuplot for years, no problems
that the excellent manual and demos haven't answered.  I still
worry about the dependence on poorly supported libgd, but no
problems so far with that, either.  Good job, and thank you,
no specific problems to report here, and thank you again!

I sometimes take the plots out of gnuplot and use libgd to
scribble on them (in for a penny, in for a pound!).  Or povray. 
I make a whole bunch of images in a directory, then stitch
them together with png2swf into SWF/flash (urk!) animations. 

One such animation (with sources) is at:
     http://launchloop.com/LaunchLoopHeating#Animation

The launchloop website is creative commons share-and-share-alike
with attribution.  Feel free to copy the code, remix it,  and
use any license you want.  I would appreciate getting back any
rewrites that turn my spagetti code into better examples,  but
any of you can have my code for free regardless.  I'm deeply
grateful for the gnuplot community that made this possible.

Again, thank you!

Keith

A final 'set output' will tidy up and close the file.

[Gnuplot-info] test. set style arrow | Blank .pdf Test Page

[mikeincousa <mik...@gm...>]

test. set style arrow 
________________________
I want to show a list of ALL the indexed arrow styles. 

This was the only command I could find but it does not seem to work.

Is this command obsolete?

How can I do this, like in the test of line style format. As in: 

gnuplot> set term postscript size 10,10
gnuplot> set ouput "test.ps"
gnuplot> test

===========================

Blank .pdf Test Page
__________________________

gnuplot> set term pdfcairo size 10,10
gnuplot> set output "test.pdf"
gnuplot> test

Renders a blank page.. What's going on in this sequence? 
Have I missed something?

Re: [Gnuplot-info] gnuplot won't plot

Hey John, 

So I'm still relatively new to terminal so my bad for the barrage of
questions. The command that you show on your last comment does not work in
my terminal?
