Re: [Gnuplot-info] problem using "set xtics x rotate by 45" when "set xdata time"

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

maybe your VALUEs were too small?
VALUE in this case is in seconds, your data are monthly data.

a VALUE of 60*60*24*30 = 2592000 gives rotated time labels.
but it's better to let the algorithm for positioning the time labels do its
work automatically
(no VALUE).

[Gnuplot-info] problem using "set xtics x rotate by 45" when "set xdata time"

[Joe <jo...@fr...>]

I am trying to rotate my xtic labels by 45 degrees.  I can
do this fine when xdata is not set to "time".  If "set
xdata time" I cannot get the labels to rotate.  I am not
sure what to set xtics equal to for time.

set xdata time
set timefmt "%Y/%m"
set xtics [VALUE] rotate by 45
plot "c:\\junk\\plot.dat" using 1:3 with lines

I've tried various numbers for VALUE but it just crashed
gnuplot.  Any tips as to what I am doing wrong?

[Gnuplot-info] Checking the return of pause -1's button press

[Suresh G. <sgo...@ya...>]

Hello,

  The following command 
      
      pause -1 "Show this message"

  puts up a dialog box with buttons named OK and Cancel.
  I would like to branch based on whether the user pressed
  on OK or Cancel.  Can this be done and, if so, how?  

  (Help shows the use of "pause mouse key" followed by 
  checking for MOUSE_KEY, but I would like to use "pause -1 ["<msg>"]
  and check for press of the OK or Cancel button.)

  Thanks,

I wonder how you arrived at this expected syntax, when the documentation

[Gnuplot-info] boxed graph question

[nocturna_gr <kos...@ya...>]

Hi,
i want to create a boxed graph with categorical data and i found this
tutorial - i am refering to the 3d graph:
[URL="http://folk.uio.no/inf3330/scripting/doc/gnuplot/Kawano/tics-e.html"]http://folk.uio.no/inf3330/scripting/doc/gnuplot/Kawano/tics-e.html[/URL]

[code]
gnuplot> set xtics ("April" 1, "May" 2, "June" 3, "July" 4)
gnuplot> plot "test.dat" using 1:2:3 notitle with boxes,\
              "test.dat" using 1:2   notitle with lines
[/code]

The problem is probably, because of the example .dat file - there is none.
Is it
"1 June value"? Is it "June 1 value", etc...

Anyway, i get boxes, that are attached to each other and i cannot get a
proper graph, as the one in the picture. Can anyone please give some
guidance?

[Gnuplot-info] Multicolored 3D scatter plot

[Robyn S. <ro...@MI...>]

Hello,

I'd like to represent some 4D data and am having trouble convincing 
gnuplot to do it.  The data consists of locations in a 3-dimensional 
volume, e.g. (r, theta, phi), with a value associated with each 
location.  I'd like gnuplot to make a 3D scatter plot, color each point 
according to its value, and display a color scale.  From the manual it 
seemed like the way to do this would be:

set cbrange [range of values]
set log cb

to color points on a log scale, and then use palette cb to make the 
colors go as I want:

  splot "density31.dat" using 1:3:2 with points lt palette cb $4

(if you're curious, the positions are actually in spherical coordinates 
using a slightly different mapping than the one in gnuplot, hence the 
out-of-order columns.)

The problem is that palette cb will apparently only take a constant 
value as an argument, so the command above fails, giving me an 
"undefined value" error on the argument to palette cb.  (The command 
works fine if I replace the column argument $4 with a constant value, 
but then all the points are the same color.)  I can probably come up 
with a way to use "rgb variable" to do this, but then I don't get a 
color scale.

There were several similar questions to this already on the newsgroup 
but most of them had either no response or a minimal (and pessimistic 
one).  Is there a way to get the output I want from gnuplot (maybe with 
rgbformulae?) or should I give up and use a different program?

I have limited access to the newsgroup but if I am able to work out the 
method of doing this I'll summarize it and document it on my personal 
website and post a link to the group, so please reply by email to me.

Thanks very much,
R

gnuplot required an explicit float.

[Gnuplot-info] Vector in 3D

I'd like to graph the vector <a b c> passing through (x0 y0 z0),

Intuitively, I should be able to give gnuplot something like:

but it doesn't seem to work; what am I missing?

Well, as it works now as you want it with the ($2+$3) thing, I am just=20
throwing out the general question as to WHY this is necessary given that th=

gnuplot that columns 3 and 4 plus y error and minus y error...

It's an honest question.

It doesn't seem that it should be necessary to go all out with the extra co=

since it automatically "knows" that a   3rd column is +/- y error bars if a=

3rd column exists and you use the switch "with yerrorbars", it should be=20

Re: [Gnuplot-info] errorbars

Thanks a lot for all your help. I finally read the gnuplot help (which i
probably should do more often :-)) and solves the problem. for everyone who
is interested.it is:
plot 'data.dat' using 1:2:($2+$3):($2-$4) with yerrorbars.
in all the other gnuplot help sites this isn't necessary. so, i dont know
how they produce their errorbars.

so thanks again for all your help.

You didn't read 'help yerrorbars' carefully enough.  You appear to have 
x:y:ydelta_up:ydelta_down data, but that's not what gnuplot expects. 
Change your data or see "help using" for how to have gnuplot change them 
for you.

Sadly, I am no gnuplot expert.  I did what you likely did and read the=20
instructions ("help errorbars", etc).  From the gnuplot help information it=
=20
is clear that 4 columns SHOULD work as you expect.  I quickly threw togethe=
r=20
a datafile that contained 4 columns of "data" with the last 2 intended for=
=20
minus and plus y error numbers.  Plotting thus, 'plot "./test.dat" using=20
1:2:3:4 with yerrorbars' produces a nonsense plot.  The x and y data is=20
plotted properly but the two y error columns are, like you experience,=20
plotted separate from the actual xy data (though the plus and minus y error=
=20
bars are correct).  Same result if I simply do 'plot "./test.dat" with=20
yerrorbars'.  Simply changing the command to 'plot "./test.dat" using 1:2:3=
=20
with yerrorbars' DID plot properly with the symmetrical y error bars=20
coincident with the datapoints.=20

What is the format of the dat file?  Tab separated data?  Comma separated? =

Are the x y datapoints plotted properly such that only the two  error colum=
ns=20
are mis-plotted?

Re: [Gnuplot-info] errorbars

[blooopsi <gr...@we...>]

the command is

plot `agevsgamm.dat` with yerrorbars

the data set contains of four columns of numbers so i think that normally it
should plot asymmetric errorbars on the datapoints which it isnt doing.it is
plotting errorbars but not on my datapoints. they are plotted below the data
points which is an absoulte miracle to me why it would do that.

thanks for your help :-)

Re: [Gnuplot-info] labelling dates on x and corresponding numbers on x2 axis

[lambert <van...@il...>]

Answering my own question (see below): 

You can bind a key that will align the x2range to the xrange simply by
typing this (or putting it in your .gnuplotrc):

bind "=" "set x2range [GPVAL_X_MIN:GPVAL_X_MAX] ; replot"

Now, each time you hit the "=" key the x2range is adapted to the xrange (you
need to redo this after each zoom).

The zoom facility of the x11 window acts on the xrange and yrange
coordinates and the x2range and y2range coordinates 'follow', but not
necessarily one-to-one. Like this the "=" key will force the one-to-one
correspondance.
