[Gnuplot-info] Fewer xticks in date mode

[Biloti <bi...@gm...>]

The graph bellow was produced by the following gnuplot command. However, the
x tick labels are too dense. How could I tell to gnuplot to use fewer ticks
in this "date mode" for x axis?

set xlabel "Year"
set key off
set timefmt "%Y-%m-%d"
set format x "%Y"
set xdata time
set mxtics 2
set ytics 0.5

set multiplot layout 2,2 

plot "dengue.csv" u 1:3 w l, "" u 1:2 w l ls 1
plot "dengue.csv" u 1:3 w l, "" u 1:4 w l ls 1
plot "dengue.csv" u 1:3 w l, "" u 1:5 w l ls 1
plot "dengue.csv" u 1:3 w l, "" u 1:6 w l ls 1

unset multiplot

As far as I know, you can replace (or also add) major tics manually. For
example (from gnuplot help xtics manual page):

set x2tics (1,2,4,8,16,32,64,128,256,512,1024)

will put x2tics at 2^n, for n=0..10, but you should add them manually. You
can even do this:

f(x)=2**x
set x2tics (f(0), f(1), f(2), f(3))

and so on, but I don't know if there is a way to force the x2tics (or any
other axes tics) directly from a function without specify them in some
sense.

Cheers,

Hernán

However, the problem I see here is that there is no "mapping" between x1 et x2 axis, though x2 axis should be a transformation of x1 axis through c constraint. Is there a way to put, for each label of x1 axis, a corresponding label in x2 axis?

Thanks again,

Hi!

perhaps this:

set x2tics
set xtics nomirror
set xlabel "i1"
set x2label "i2"
set ylabel "o"
plot 'myfile' u 1:3 w l t "o(i1)", '' u 2:3 axes x2y1 t "o(i2)"

hope this help. See help axes for further info.

[Gnuplot-info] multiple axis with constraint

[Martin G. <mg...@lb...>]

Dear GNUPlot:

I have a system with two inputs (i1 & i2), and one output (o).
The two parameters are linked by some kind of constraint (c1(i1, i2) = 0).
I have data in the following format: #i1 i2 o.
Of course, I can easily plot o(i1) and o(i2).
I would like to create a plot where I have i1 in x1 axis, and corresponding i2 in x2 axis, while having o in y1 axis.
Another way to say it is to have, for each tick in x1 representing i1/i2, the corresponding tick in x2 representing i2/i1 (constraint c1 is fairly easy to solve analytically).
Does it make sense to anyone?

Thanks i advance for your help.
Martin.

I appreciate your comments.  I realize ^L clears the
screen.  My app normally runs from within emacs and I
sometimes capture hundreds of thousands of lines of
debugging output in a single emacs buffer.  This can be
navigated thru using a whole collection of custom elisp
functions.  Emacs is remarkable tolerant about these
large files.  Any how, that's my use case.

The ^L should work better for interactive sessions,
as you suggest.

thanks for your reply

And if you're on an actual interactive terminal, which is what this 
terminal is primarily intended for, that's quite a nice thing, really, 
because it positions the plot on a new page, where it'll stay at the top 
without moving, while you enter the next commands.

Well, adding clever options like that to a terminal driver calling 
itself "dumb" would, kinda-sorta, defeat the purpose.

Re: [Gnuplot-info] question on label positioning / syntax of coloring commands

[Dr. I. D. J. <die...@t-...>]

Hi Thomas,
thank you very much for this information. IMHO a reference to  the 
"coordinates" syntax would be very helpful in the "label" documentation. 

It is not self-understanding to look for set coordinates when I am seeking for 
information about labels. An issue for the gnuplot-wish list (I guess it is 
unlimited like the Richter - scale  :-))

Secondly, wouldn't it make sense to make a consistent syntax? 

Using 
plot XYZ axis x1y2 ....

in plots in contrast to 
set label "LABEL" at first X, second Y

is again not self explanatory.

What regards the color specification I agree - just missing an idea how the 
reader could be pointed to looking for "set textcolor" based on the 
information provided by "help set label"; basically a similar issue as above. 
Maybe using capital letters for entries that are of composite type to indicate 
to search there? Just an idea ....

Anyway, thank you very much for helping!

Take care

'help textcolor' says:

...
 Syntax:

       ... {linecolor | lc} {<colorspec> | <n>}
       ... {textcolor | tc} {<colorspec> | {linetype | lt} <n>}

 where <colorspec> has one of the following forms:

       rgbcolor "colorname"
       rgbcolor "#RRGGBB"
       rgbcolor variable       # color is read from input file
       palette frac <val>      # <val> runs from 0 to 1
       palette cb <value>      # <val> lies within cbrange
       palette z
       variable                # color index is read from input file
...

a simple number for textcolor as <colorspec> means nothing,
there is no predefined "colortype" (in contrast to 'linetype')
which one could use.
either you may use the color of a predefined linetype
or you may give the full color specification.

[Gnuplot-info] terminal dumb plot inserts a form feed char

[Robbie M. <ro...@ac...>]

Hello all

I noticed that the "dumb" terminal, by default, inserts
a "^L" (form feed char, decimal 012) before plotting.

I normally capture the output, which is then duly
peppered with these little form feeds.  I wonder if a
better default would be to omit the form feed unless
otherwise requested.

Please note that I do not issue a 'clear' command,
which Janert (2010 p218) ["Gnuplot in Action"] suggests
should "forces a form-feed or page break" in this case.

Just a thought for the doubtless overworked
maintainers.  And I could of course deal with this
on the client side.

best wishes, Robbie

Re: [Gnuplot-info] change the output from landscape to portrait

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

Dear Hans,

Thanks for your answer. I used eps option and it does cure the problem I
raised. I would like to ask though, if I don't use eps, then a correct eps
file can still be generated and recognized. It seems to me the only
difference with or without eps option is to generate a graph which can be
fit into an A4 page either standing up or laying down (sorry for not being
able to find the correct expression for that).

And, if I don't use eps option, can I make full use of gnuplot commands to
achieve the same effect? I tried to use {10,5} to make a graph with width
larger than height, but it does not work that way, so how come?

Thanks,

Sincerely,
Jon

[Gnuplot-info] question on label positioning / syntax of coloring commands

[Dr. I. D. J. <die...@t-...>]

Dear listmembers,
I have two questions:

1.) is there a way to align labels vs. x2 or y2-axis? From the online help I 
cannot see an option like

set label "TEXT" axis x1y2 at 1.5,0.7
                 ^^^^^^^^^

specifically if you have a log - axis on one hand and a non-log axis on the 
other this would be quite helpful.

2.) if I read the command description it says

set label .....
............
............
{textcolor <colorspec>}
{point <pointstyle>}


given this, I would expect to say

set label "TEXT" at 1.5,0.7 tc 3

However, what I have to write is

set label "TEXT" at 1.5,0.7 tc lt 3

otherwise it does not work. This is not how I would interpret the given syntax 
and I cannot imagine anyone who would. Why do I have to reference a linestyle 
to specify a text color? 
Is this an error in the online documentation? It may be a necessity from 
programming standpoint, but from a logical standpoint and from a usability 
standpoint it is somewhat strange. 

I would expect "tc" to depict what the user wants to say. Textcolor, that's 
it. Just my two points after hours of struggling ..... :-)

Thank you for looking into this,
take care

[Gnuplot-info] change the output from landscape to portrait

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

Dear All,

I have been very frustrated to change the output into eps/pdf as a portrait
orientation but maintain the right ratio between x and y axis. I used
command

set term postscript portrait color solid enhanced

to try to generate a portrait output, but y axis is obviously too elongated.
If I add {10,5} into the set comand to enforce x > y, it does not seem to
work. Anyway, I just want the plot to be plotted in a rectangular just like
a landscape box but with the whole plot rotated 90 degrees. How can I
possibly do that?

Thanks,

Sincerely,
Jon

Of course it does.  == is an operator for numbers, but you're passing it

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

Dear All,

I use macro to control whether output to a file or on screen by defining a
variable debug. I would like to output a string on screen to remind me where
the output is by writing code like

debug = ''
print (debug=='#' ? 'output in file' : 'output on screen')

However, gnuplot complains that

Non-numeric string found where a numeric expression was expected

How can I possibly circumvent this error and get what I want, thanks!

Sincerely,
Jon

"%U" is only valid for "set format" not for "set timefmt".

see chapters 75.23.3 and 75.70 in the manual.

[Gnuplot-info] using week number in timefmt

[Mikhail K. <mko...@gm...>]

i am trying to use week number in timefmt specification, e.g.

set timefmt "%Y%U"
plot "2008-weekly-medianed.txt using 1:2 w lp

and receiving many lines like that:

2008-weekly-medianed.txt:11:         warning: Bad time format in string
200839  +3.408884e+002

is it possible to do it as it is described in the manual? for now i have 
to use %Y-%m-%d specification unstead?

all the best,
Misha.

Re: [Gnuplot-info] Multiplot horizontal scrolling

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

a small example (tested with the 'x11' terminal):

data.dat:

1 1
2 4
3 2
4 1
5 5
6 3
7 4
8 2
9 1
10 5

main.plt:

reset
set macro
set xrange [0:11]
set yrange [0:6]
i=1
n=5
load 'loop.plt'

loop.plt:

temp = "call 'plot.plt' 'data.dat' ".i." ".n
print temp
@temp
pause mouse keypress
if (MOUSE_KEY == 43) i=i+1
if (MOUSE_KEY == 45) i=(i>1?i-1:1)
print MOUSE_KEY
reread

plot.plt:

plot '< tail +$1 $0 | head -$2' with linespoints

start with loading 'main.plt' and use the '+' or '-' key when the
mouse pointer is in the plot window.

[Gnuplot-info] Multiplot horizontal scrolling

[babelproofreader <bab...@gm...>]

I am plotting a multi-plot plot which has 3 separate plots on the screen and
which is called thus, using the head/tail syntax

call 'all_plots' $gc 150 5000 11 1

which plots 150 points of the file, ending at line 5000 (and where 11 and 1
indicate which columns of the file to plot via if/else statements). At the
moment to scroll through the file I am manually changing the line ending
input (e.g. 5000) but this is laborious. Is there some way I can rewrite the
script so that I can scroll by, for example, hitting a designated key such
as the space bar, to scroll through one line at a time?

Re: [Gnuplot-info] Plot two or more functions

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

set the same 'xrange' and 'yrange' for all plots.

position the keys for each plot individually with
set key at ...

Re: [Gnuplot-info] Plot two or more functions

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

either plot the function first:

plot sin(x)
replot "-"
2 2
1 -1
...
e

or use 'multiplot':

reset

set multiplot

set xrange [] writeback
set yrange [] writeback

plot '-'
2 2
1 -1
...
e

set xrange restore
set yrange restore

plot sin(x)

unset multiplot
