My apologies if I seem ignorant, but I did read all that before posting,
which is why I was using %s and not %S in the first place. Testing shows
that %S works well up to 99, and not 59 however. The documentation of
timefmt says about %S:

       %S           second, integer 0--60 on output, (double) on input

Which implies that output is limited from 0 to 60, but input is not.

It seems, because I still can't get it right.

Well, that's funny, I don't! The following snippet still gives me a
crooked line:

http://i.imgur.com/xaEOyPm.jpg

-------------------------
set xdata time
set format x "%M:%S"
set timefmt "%s"
show format
show timefmt

plot "-" using 1:2 with lp
1       0.5
2       1
3       1.5
4       2
5       2.5
6       3
EOT
---------------------------

Output of 'show format' and 'show timefmt'

tic format is:
  x-axis: "%M:%S"
  y-axis: "% g"
  x2-axis: "% g"
  y2-axis: "% g"
  z-axis: "% g"
  cb-axis: "% g"
  r-axis: "% g"


read format for time on x axis is "%S"
read format for time on t axis is "%S"
read format for time on u axis is "%S"

Tried %S as well, but this breaks down as soon as the time in seconds
exceeds 100:

So I must still be doing something wrong?

> 2. note information about time format both for data AND for plot

Actually I want the X axis to show time in [HH]:MM:SS format, which is
the reason to choose 'xdata time' at first.

So:

- input time is seconds starting at 0
- output is time in 'human friendly' notation [HH]:MM:SS

-------------------------
set xdata time
set timefmt "%S"
set format x "%S"

plot "-" using 1:2 with lp
1       0.5
2       1
3       1.5
4       2
97      48.5
98      49
99      49.5
100     50
101     50.5

[Gnuplot-info] relative second time data

[<gn...@ze...>]

Hi Gnuplot-info, 

I'm trying to plot data on a relative time scale starting at 0 the input
is a column of seconds and a column of data.

---------------------------
set xdata time
set timefmt "%s"

plot "-" using 1:2 with lp
0       0.0
1       0.5
2       1.0
3       1.5
EOF
---------------------------

can someone explain why I get these results:

http://i.imgur.com/lBmk5di.png

The data should be a straight line, but gnuplot seems to have a problem
dividing the X asis when using time.

Thank you,

Yes. That is too old (Sept 2009).  In that version the x11 terminal did not
support control of aspect ratios.

Yes, this is what I would like to achieve. If you think you can achieve the
effect I am after, could you please send back your plot based on my input

I did replot after changing these settings, but don't see any change, which
surprises me.

Thanks for further help, my gnuplot version is 4.2 patch 6, is this too old
a version?

So if you had filled both x and y it would have been a square, right?
Isn't that what you wanted?

Neither.  "set view" cares about the coordinate system itself, 
regardless of what points you do or do not plot.

"set view equal xyz" gives you an orthogonal coordinate system so 
that a line segment from [a,b,c] to [a,b,c+1] has the same apparent 
length as one from [d,e,f] to [d+1,e,f] and so on.

It  controls the size of the next x11 plot window you open.
It does not change what is already on the screen.

Re: [Gnuplot-info] how to make a 3D plot shown as in a cube?

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

Thanks for your response. I did have points on x axis twice that of y axis,
but x,y range are the same, both from -1 to 1. Would set view care about
how many points along each axis or it only cares about the values to be
plotted?

BTW, why would the following two commands

set term x11 size 10,600

set term x11 size 600,600

have no control on the output on the screen?

Can anybody comment on that?

Sincerely,
Jon

But you didn't draw a square.
As is clearly visible in the figure you attached, you drew a
rectangle that is 2 units by 1 unit.   

The "set view equal xyz" command makes sure that the unit length
is the same on all  axes. I.e. the aspect ratio is 1.
But it's still up to you to draw something with the right dimensions.

Hi Guys,

I have been fighting with it for some time and would like to know a
solution. I want the 3D plot to be shown with a cube with actual equal
length of x,y,z.

Thanks,

The problem is that you have too many blank lines in your data.  The 
separation between blocks to be referenced by `every' is _one_ blank 
line, not six.

Multiple consecutive blank lines create the separation used by "index".

Hi guys,

I had supposed I understood the concept of block, but it turned out I
cannot make the following file correctly read in by the command plot.
Thanks for your timely help,

Sincerely,
Jon

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

The script is

p [0:] 'DY_SLICE_HIST_1'  \
     u 1:2 ev :::1::1 w lp, \
   0 w l lt 0 noti

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

The error message is:

Warning: empty y range [0:0], adjusting to [-1:1]

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


The data file is:

Assumpte: Fitting output data of a fortran script by modifying input of the script 
 
Hi everyone! 
I'm totally new in gnuplot and the thing is that I'm trying to fit an spectra that can be deconvoluted in 8 functions. But the data that I want to fit must be processed before the fitting, so I made a fortran program to process it. Is there any way with gnuplot to fit the output data of my program but modifying the input data iteratively? 
Thank you!

[Gnuplot-info] gnuplot functions for cartographic projections

[Joseph G. <jos...@ya...>]

 Hello,
 Here is a library of gnuplot functions for cartographic projections in 2D and 3D

https github.com/tuxcell/gnuplotcartography
run
gnuplot demo1.gnu
gnuplot demo2.gnu
gnuplot demo3.gnu


And an R-package (Programming interface):

The R package can create maps for gnuplot from image files (jpeg, PNG, etc) or shapefiles and plot them in over a dozen cartographic projections

Re: [Gnuplot-info] path contains hyphen "-"

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

sorry, my mistake ... but gnuplot might have output inconsistent error
message,

actually it is the y range which is invalid.

y column is beyond the valid range in the dataset.

[Gnuplot-info] path contains hyphen "-"

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

Dear All,

I am trying to plot the following

p 'test_tJ_rep_10_NanNNHop/1.0/-0.25/12.0/12t90u95aa.j' u 1:9 ev ::500 w p

it complains

x range is invalid

It seems not an issue with finding the file, as otherwise it will complain

warning: Skipping unreadable file
"test_tJ_rep_10/1.0/-0.25/12.0/12t90u95aa.j"
         No data in plot

I thus wonder whether this is related to the hyphen used in the path. If
so, how to fix it?

Thanks,

Sincerely,
Jon

The color sequence of the two histogram plots can be controlled
by prefixing each with the "newhistogram" command.
E.g.
 plot 'data' using ... ,\
 newhistogram lt 1, for [i=3:19] 'data2' ..., \
 newhistogram lt 1, for [i+3:19] '' ...

[Gnuplot-info] Iteration with two commands

[<tar...@gm...>]

Hi,
I'm trying to build a sort of bar-chart using a simple
data file (data_dlex) containing only 0 or 1. I'm using the following code:

set style histogram rowstacked title textcolor lt -1
set datafile missing 'nan'
set style data histograms

plot '.data_dglob' using 2:xticlabel(1) lt -1 ,\ 
'.data_dlex' using ( $2==0 ? 1 : 0 ) ls 17 title 'NA' ,\ 
'' using ( $2==1 ? 1 : 0 ) ls 1 ,\ 
for [i=3:19] '.data_dlex' using ( column(i)==0 ? 1: 0) ls 17 notitle ,\ 
for [i=3:19] '' using ( column(i)==1 ? 1: 0) ls i-1

where the last two commands iterate over a potentially large number of
columns stacking white or colored boxes depending on the value of column
(i). To keep the same color order among different columns I would need to
merge the two iterations into a single one with two commands.

Is it possible? Any suggestion on how to do that?

Thanks in advance.

It works!  It's an obscure glibc option; thanks.

You sure it's the shell, and not the GP assignment "month = 08" ?

I suppose I'll have to pipe it through "sed" or something; talk about 
violating the POLA...

depending on the version of "date" you may
switch padding off:

#> date +%m
08
#> date +%-m
8

[Gnuplot-info] Possible to display x/y axis labels in color?

[Kevin K. <kk...@gm...>]

Suppose I have a plot where the y-axis labels are: 0, 100, 200, 300, 400
... 1000.  Is it possible to display the 200, 300, and 500 labels in red,
but the other labels in black?

Thanks

Kevin
