I use this gnuplot script ( I'm bound to use the 4.6 version of Gnuplot ) :
Code:
reset
FILE = "LINEARFIT.txt"
set datafile separator ";"
set xdata time
set timefmt "%Y-%d"
set format x "%Y\n%d"
plot FILE u (StartDate=timecolumn(1)):0 index 0 every ::0:0:0
EndDate = strptime("%Y-%d","2020-20")
f(x) = a*(x-StartDate) + b
FIT_LIMIT = 1e-8
fit f(x) FILE u (timecolumn(1)):2 via a,b
set terminal png truecolor size 900,520 background rgb "#eff1f0"
set output "/xxx/xxx/xxx/xxx.png"
set xrange[StartDate:EndDate]
set grid xtics, ytics
set yrange[0:30]
set format y "%g"
myLabel(n) = sprintf("%g",n)
plot FILE u (timecolumn(1)):2 w lp pt 7 lc rgb "red" notitle, \
'' using 1:2:(myLabel($2)) w labels offset 0,-0.5 notitle, \
f(x) ti "linear fit with extrapolation"
And the output is :
Can you tell me why, on the x axe, the values are displayed "Two by two" : 2020-04, 2020-06, 2020-08, 2020-10, 2020-12, 2020-14, 2020-16, 2020-18, 2020-20... While I want 2020-04, 2020-05, 2020-07, 2020-08, 2020-09, 2020-10, 2020-11 ,2020-12 ....
Hi, I am a beginner using UNIX, and was wondering how to use gnuplot from UNIX on my pc. I am connected remotely to my work's UNIX server using Secure Shell Client, and gnuplot won't open a new window when I use the plot command. How do I do this?
Moreover, is it possible to save things from the... (0 Replies)
Hi guys,
I have a AIX 4.3 system, and I need to configure a printer, but that printer it's connected to a axis print server. I have lot of years working with unix, but never added a printer in a AIX system. I need to add using "remote print queue", and add the hostname and ip to the /etc/hosts?... (2 Replies)
I'm using my wife's Macbook, and I just noticed that her screen is off axis, but I can't find a way to adjust it. I've tried playing around with resolution in preferences, but nothing.
Maybe a terminal command for adjusting the x and y values of the screen?
Any and all suggestions welcomed :) (2 Replies)
Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:
for example plot filename.txt
It says that (.txt ) is not identified ... I tried to write it without the .txt part, but I also get the error msg.
Any idea why? :confused: (1 Reply)
Hi All,
Seems I have an xargs stdin problem that I don't understand.
I have a script (call it myscript.sh) that takes the names of one or more file(s) specified on the command line and creates a single gnuplot command file containing multiple records, one for each specified file. Each of... (9 Replies)

Hello
I have a text file with tens of thousands of rows
The format is

asql
ASQL(8) Perl Programmers Reference Guide ASQL(8)NAME
asql - Provide an SQL interface to Apache logfiles.
SYNOPSIS
asql [options]
General Options:
--help Show brief help intstructions.
--manual Show more complete help.
--version Show the version of the software.
Scripting Options:
--load Load the named file, or glob.
--execute Execute a single query then exit.
Options:
--file Rather than running as a shell read commands from a named file.
--quiet Don't show the banner at startup.
DESCRIPTION
asql provides a simple console interface to allow a user to
query the contents of an Apache logfile via an SQL interface.
The shell features include:
Persistent alias definitions.
Command line completion
Command history
Simple scriptability
INTRODUCTION
The asql shell will create a temporary SQLite database based upon
any number of Apache logfiles. This temporary database may then
be interactively queried using common SQL syntax.
To get started you should load your logfiles into the database:
load /var/log/apache2/acces*
(The tool will automatically decompress files which have been
compressed with gzip or bzip2.)
Once you've loaded at least one file you may run queries, for
example:
SELECT source,SUM(size) AS Number FROM logs GROUP BY source ORDER BY Number DESC, ip
This example shows all the clients connecting to your webserver
and the size of files/requests that they have downloaded in total.
As you can see we've selected two columns "source" and "SUM(size)".
To see which other columns are available you may execute the "show"
command.
Because parsing the Apache logfile(s) specified might be quite
slow there is the option of dumping the temporary SQLite database
to a known filename with the 'save' command. The analog to the
save command is the 'restore' command, which will read in an
existing SQLite database and allow future queries to be executed
against it.
FILES
When the shell starts up it will read and intepret the initialisation
file of ~/.asqlrc if it exists. Any commands present in that file
will be executed prior to the launch of the interactive session.
All aliases will be read and written to the file ~/.asql.aliases.
All interactive history will be written to the file ~/.asql.
