Re: [Gnuplot-info] Basic question: how to plot the data on a bar chart?

[<rhu...@ih...>]

Thanks this gets me much closer. 
I don't feel so bad now. That isn't as simple as I had expected.

Now I need to figure out how to add some additional logic to position the label
for those bars that are shorter than the number of chars in the label. I think I
can use a -/+ offset based on the bar size.
 
I tried

gnuplot> help $0

But didn't turn up anything and the mention of $0 in the doc
wasn't enough. Is the $0 in this case relative? 
i.e. is it the position on the x-axis of the x-value from "using"? 

I thought $1 was the first column of the data file so $0 is still unclear to
me.

One thing I found was that the Index in the 4.4 gnuplot.pdf is empty/blank.
Intentional? Or a bug?

You'll probably want to change that to Ctrl-H.

Note that setting: it's showing right the kind of escape sequence that 
ends up on screen in your gnuplot session, doesn't it?

So either you need to change this, or you need to change your Linux 
session's configuration to match it.  That's where TERM comes in.

These mean your X11 terminal must _not_ be in "Application cursor keys" 
mode.

Then you should probably be using Linux or XTerm R6 for the function key 
setting.

That may add new layers to the problem.  You may be better off trying 
off the original PuTTY.

Look up "help expressions", read up on string operations, then follow

[Gnuplot-info] character replacement functionality?

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

I need to use gnuplot to quickly glance whether a sequence of data follow a
reasonable pattern, thus I need to modify a figure in the datafile name to
achieve it. For example,

p 'a1000_phi_24' u (f($1,width)):(1) smooth freq with
boxes,'a1000_phi_24.hist' u 1:2 w p,'a1000_phi_24.hist2' u 1:2 w p

where 24 will be replaced by 25, 26 ,...

I am wondering whether I can do something like the following:

define a string as

s=24,

and issue a command as

p 'a1000_phi_'+str(s) u (f($1,width)):(1) smooth freq with
boxes,'a1000_phi_'+str(s)+'.hist' u 1:2 w p,'a1000_phi_'+str(s)+'.hist2' u
1:2 w p

just like in python. Then I can change s=24 to s=25, etc, thus easily plot
according to the rest data files.

Thanks for your hints!

[Gnuplot-info] Basic question: how to plot the data on a bar chart?

[<rhu...@ih...>]

I just want to plot the underlying data for each bar on the bar itself.
Can someone show me how to do so using this page?

http://www.bmsc.washington.edu/people/merritt/gnuplot/

go down to:  Histogramming Tabular Data

On that histogram I would like to plot the y-values on the bars.


I am using:

For the putty setting, go from putty -> change setting -> terminal ->
keyboard, there are a lot of options and I list them here

Change the sequences sent by:
The Backspace key  --  Control+?(127)
The Home and end key -- Standard
The Function keys and keypad -- ESC(n~

Application keypad setting:
initial state of cursor keys: -- Normal
Initial state of numerical keypad -- Normal

Enable extra keyboard setting: Control+Alt is different from AltGr

------------------------

For your information, I also list choices in putty -> change setting ->
terminal,
Set various terminal options  (checked)
   Auto wrap mode initially on
  Use background color to erase screen

Answerback to ^E:   -- putty

Line discipline options:
Local echo -- Auto
Local line editing -- Auto

-------------

There are several options for the three items, I tried to modify to other
options, but does not help in gnuplot, the keys changed from 1~ to wH etc.

For the command "echo $TERM" running on the remote computer, it returns
xterm.

The version of putty I used is 0.60 with Cyg enhanced, that is, it is
puttyCyg

Thanks for further help!

It's pretty much impossible that that would have anything to do with the 
problem.  This is happening several layers of software away from the 
physical buttons.

For starters, inspect all settings of PuTTY in the "Terminal" folder of 
the options dialog, and do a

	! echo $TERM

in your remote gnuplot session (or just

	echo $TERM

directly in the remote shell, before starting gnuplot).

This could be the case as well. The laptop I am using is lenovo x61s. The
whole keyboard is separated into several "isolated" parts. The
misfunctioning keys are separated from the character keys and are located on
the very upper part of the keyboard. So, it could send some unusual
character encoding. The reason I didn't doubt this too much is that these
unusual character keys(if there were) can be correctly interpreted by the
remote computer's linux system. So, why not within gnuplot?

Please let me know how to check "TERM environment variable, gnuplot build
options (readline or not), and the settings of your terminal emulator (PuTTY
in your case)" I am not familiar with these things, thank you very much for
your kind help.

Re: [Gnuplot-info] erratic key stroke response in gnuplot

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

Thanks, I would guess the same on my local computer. I let it installed by
ubuntu itself. I have no idea on how it is actually carried out.

But for this remote computer, I would trust that the administrator(my friend
and is very good at linux, but I cannot reach him these days) has done it to
perfection. That could be too arrogant, here are some facts I noticed, don't
know whether these are only provided by readline support

it can copy and paste as usual, it responds well to arrow
up/down/left/right, it has .gnuplot_history at user's home directory. I
never tried key bindings, so I don't know that.

Re: [Gnuplot-info] how to adjust legend font size?

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

Thanks, I will do this the next time, now I really cannot recall it. I have
found a solution to use the so-called enhanced format

p '***.txt' u 1:2 w d title {/Times=20 kljlkjf}

to do it. It works fine when in .pdf or .eps file, but not intended under
x11. I cannot understand why since a larger display of characters should
still be within the capability of x11. Further alternatives to do this is
highly appreciated!

You could start by actually _showing_ us how you tried to use 'set key' 
to change the font, and the actual error message that yielded.

It is.  It's regularly caused by a mismatch of the character encoding 
used by the terminal (emulator) and the terminal setting.  Double-check 
your TERM environment variable, gnuplot build options (readline or not), 
and the settings of your terminal emulator (PuTTY in your case).

Re: [Gnuplot-info] erratic key stroke response in gnuplot

[Johannes R. <ja...@ho...>]

 It sounds to me as if your version of gnuplot is not compiled with
readline support.  readline is the library which is responsible for all
the nice editing features, including the history and the key bindings.

Did you compile gnuplot yourself?

[Gnuplot-info] how to adjust legend font size?

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

use the command

p '***.txt' u 1:2 w d title 'kljlkjf'

but how to adjust the title size to bigger?

It seems set key does not work, (would not recognize font option, don't know
why, version 4.2), it seems no font size control on the title text in the
plot statement, what else can I think of ... Thanks!

[Gnuplot-info] erratic key stroke response in gnuplot

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

Dear All,

I had raised this issue some time ago, but was persuaded that it could be
due to the operation system setting instead of gnuplot itself. Since I am
not very familiar with the linux system on my local computer, I gave it up
as it is.

Now, I tried to use putty (with -X option on) to connect to a remote
computer and run gnuplot there. The remote linux system can correctly
respond to the keys of insert, delete, home, end etc, but when I get into
gnuplot, these keys cannot be recognized. For example, insert is shown as
2~, delete is shown as 3~ .... Any idea on what could be the reason?

Thanks for helping me out on this issue

Sincerely,
John

[Gnuplot-info] Unrendered Quadrangles

[Christian S. <csc...@uo...>]

Hi,

Thanks for reading my mail.

I'm using the most recent version of Gnuplot for windows, 4.4.0 I think.

I have a 64x64 value data file which plots perfectly using:

plot "datafile.txt" matrix with image

However, when I wish to create an associated surface plot using:

splot "datafile.txt" matrix with lines ls 1

Gnuplot seems to "forget" to render certain quadrangles - roughly a dozen, maybe - near the back of my plot. The result is a surface plot with strange holes in it! 

??!!

Any ideas how I can fix this?

Previous to the splot command are the following:

set terminal postscript color rounded size 8cm,8cm enhanced eps
set output "surf.eps"
set palette maxcolors 0xFF
set nokey 
set noxtics
set noytics
set noztics
set border 0xF
set size square
set xrange [0:63] 
set yrange [0:63] 
set zrange [0:25] 
set cbrange [0:]
set xyplane 0
set style line 1 linetype 1 linecolor rgb "white" lw 0.03125
set hidden3d offset 0 front
set pm3d

Any help is appreciated. I must admit, I'm even at a loss as to what to search for in an attempt to solve this problem myself, though I've tried. Sorry if I've missed something obvious, and thanks again for your time.

You'll have to remove sargraph from the picture before this can be 
treated as a gnuplot problem.  That means you have to find out the exact 
command sequence set up by sargraph, and check it directly in gnuplot 
yourself.  As is, gnuplot's error messages appear to go straight to 
/dev/null.

It could be something simple, like the PNG driver missing from your 
gnuplot executable.

Now plot your data using

where column 1 contains x-coordinates, 2 contains y-coordinates and 3
contains whatever labels you are interested in.

Hitting o in the interactive window now asks you for two points and prints
the labels/keys of the points contained in the specified rectangle to the
gnuplot terminal.

[Gnuplot-info] Back reference to data in interactive terminal

[till_hm <ti...@gm...>]

Hey,

I was wondering whether there was any way to get a back reference to the
original data from a scatter plot in an interactive terminal.

In particular, I have a dataset where each entry is identified by a unique
number. Given a scatter plot I would like to be able to make a mapping from
points on the plot to my original data. Using labels does not seem feasible
because I have ~10^5 datapoints.

Thank you!

Till

Thanks Thomas, that worked great. I never knew about these internal variables.
I am curious about specifying xrange after the first plot command instead of before.

I tried doing it before the first plot but it didn't work. I'm guessing that the x values
don't get initialized until a plot command is given.

Re: [Gnuplot-info] xaxis alignment for multiplot

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

after the first plot command:

set xrange [GPVAL_X_MIN:GPVAL_X_MAX]

[Gnuplot-info] xaxis alignment for multiplot

[<rhu...@ih...>]

I have a multiplot with 4.4p1

The x axis is time data

I run

set multiplot layout 5,1 title "test"

set xdata time
set timefmt "%Y%m%d"

set tmargin 0
set bmargin 0
set lmargin 4
set rmargin 4

plot "f" u 1:2 w l
plot "f" u 1:3 w l
plot "f" u 1:4 w l


set format x "%Y%m"
set xtics nomirror

plot "f" u 1:5 w l

The plots have no space between them and the plots before the "set xtics"
start at the left-most point on the x axis but the last plot after "set xtics"
Has a gap then the data is display along the x axis.

I don't want to have to specify the start point for the x axis as it requires
extracting that from the data.
Is there some other way to make this work?
