I'm curious if anyone know how to plot stem-and-leaf plot using perl? Basically, what I was wanting to do is read a bunch of numbers from a text file into an array, sort from smallest to biggest, and plot the following (last digit serves as the "leaf", so for example, for the following graph, going down from top to bottom is 7, 7, 12, 13, 18, 18, 23, 25, 27, 27, 27, 27, 27, 27, 28, 28, 29, 59, 30, 31, 31 etc.):

I want to use xplot in order to plot a spectrum but when I executed the code by typing "xplot qso.fits" in terminal it returned the following error one after the other so I was force to stop the program using "Ctrl + C". (I am using Ubuntu 10.4 and I have also PGPLOT installed on my Linux).

View 13 Replies View RelatedIt's been a while since I did any kind of graphics programming, but I would like to start learning how to do graphics stuff in *nix. I started reading the GTK+ 2.0 Tutorial, but a) I've only been able to write a small "Hello World" program, and that tested my patience, and b) I'm not seeing anything which allows you to plot a pixel directly. Back before I migrated to Linux, I used the Windows GDI SetPixel() function for plotting pixels sequentially (this was for a small fractal generator). Mostly what I'm asking is if there's any kind of equivalent function in *nix graphics APIs? GTK+? Would I have to deal with SDL/OpenGL?

This is not happening in gnuplot script I have written, it holds the current window and plots the next data on the same window.A way I found to see separate plots was to use multiplot, but this plots multiple plots in the same window. Can someone tell me how to plot multiple plots in separate window in gnuplot? I could not find the answer in documentation/man pages.

I'm running Maverick on an HP dv6 laptop. I tried recording a video via VLC with the machine's 'TrueVision' webcam. The result seemed to lack audio, so I had a look in preferences > sound. The input tab had the mute button ticked, so I unticked it and tried adjusting the level (while realising I was probably just configuring the mic port and not the webcam's inbuilt mics).
Then things turned bad: pointer became sluggish, and changes I made to the level slider took ages to be reflected visually on screen. I queued up a pile of clicks on the 'close' button and went away for a while. On return, I was met with a box inviting me to stop a script with some screen-width-long incomprehensible name, which of course I did.
Now the system's in a state which sees windows missing title bars (tho' not menu bars) and (more problematically) the upper and lower bars on the desktop absent. I issued a hibernate command from the terminal in the hope that on waking the system would be 'fixed', but nothing changed. I tried alt-tabbing to access my open applications and close them gracefully but this command is ignored. I have 'zillions' of apps going with unsaved data and am not sure what to try next. I'd be happy just to be able to task switch to each open prog and exit it gracefully then restart. But my knowledge of the command line is such that your help is required =) .
The current Octave 3.4.0 on Fedora 15 is giving me an "out of memory" message when I plot certain data. See example below. It depends on the range, and the particular function. Anyone else get this behaviour?

I would like to use a package manager to generate a list of all installed packages that are not depended on by any other installed package. That is to say, a list of installed packages that are not required by any other installed package. I believe these are referred to as packages with 0 forward dependencies. I believe they are also called "leaves."
I am on Red Hat, so a method of doing this with rpm, yum or smart would be optimal. I discovered the package-cleanup program that is a part of yum-utils. According to package-cleanup's man page, the option --leaves will "list leaf nodes in the local RPM database. Leaf nodes are RPMs that are not relied upon by any other RPM." I thought this would do what I wanted, but it seems to do a poor job. It listed only two packages. While those two packages are indeed required by nothing else, I am sure there are many more than two on my system. (For example, it did not list firefox)

View 1 Replies View RelatedI am searching for a program which may be used in order to display a list of "leaf" packages (i.e. installed packages upon which no other installed packages depend), but only those "leaf" packages which are not marked as being mandatory packages belonging to some installed group. For example, assume we have package group "Example" which comprises the following packages:
core-package-one [ MANDATORY; installed; ]
core-package-two [ MANDATORY; installed; ]
extra-package-alpha [ OPTIONAL; installed; not required by any other package; ]
extra-package-beta [ OPTIONAL; installed; required by extra-package-alpha; ]
extra-package-delta [ OPTIONAL; not installed; ]
Format: <package name> [ <group priority>; <install status>; <leaf status> ]

If such a tool does not exist, I would like to create it. However, I am new to RPM-based systems, and, as such, I am having difficulties finding the necessary documentation. Should I be reading the yum source code? Is there some sort of document describing the package database on RH/CentOS/etc. systems and how 3rd party applications are supposed to work with this database?
I have a small problem with Perl and Apache.
If I use "#!/usr/bin/perl" in the beginning of a perl script the script won't work if the script is at all complicated. Simple scripts like "Hello World" works.
But if I use "#!/usr/bin/perl -w" in the beginning all scripts work?
If I don't use the -w this is whats in the logs:
(2)No such file or directory: exec of '/home/test.net/html/cgi-bin/uh/meny.pl' failed
Premature end of script headers: meny.pl
When I use the -w in the script the error-log shows me this.
meny.pl: Name "main::http_path_cgi" used only once: possible typo at /home/test.net/html/cgi-bin/uh/meny.pl line 24.

I recently reinstalled the B module for perl. Now I found out it didn't just do that, it installed a whole new copy of perl into /usr/local/bin/perl. When I type 'which perl' at the terminal, it says '/usr/local/bin/perl' instead of '/usr/bin/perl'. Normally, this wouldn't bother me. But I installed the one in local/bin without threading support. The one that comes with the system already is build with threading support, which is why I want to switch back to the system perl, and possibly remove the one in /usr/local/bin.
So how do I change it so that the result of 'which perl' returns as '/usr/bin/perl'? And what do I have to do to remove /usr/local/bin/perl?
The reason I need threading support is because I'm designing a file copier that copies several chunks of a file simultaneously to speed up the copying process. Guaranteed a useful script if it works.
I'm new in perl programming and linux OS. What is the difference between perl and perl-devel? What does mean devel? Iwant to install Catalyst and before install as required I have to check if make, gcc and perl-devel are installed in my system. make and gcc are installed. But I have to install perl-devel. First I searched for make, gcc and perl-devel in YAST Software Management and search did not find perl-devel. I visited the software.opensuse.org and wrote "perl-devel" and searched. The result was many similar zips with a prefix perl-devel and I can not choose one for needed perl-devel.

I had a problem recently, where a perl script was consuming server resources. I found out it was a perl script by using "top". But it didn't give the path to the script. Nor did ps.Also, ps -ef showed that the process with that pid is /usr/bin/httpd (apache), so it must have been apache serving some perl page I suppose.Is it possible to get the path to currently running perl script, if I only know the process PID of the perl process that is running that script? If so, how? I don't need the path to the perl binary, I need the path to the perl script that binary is currently executing.
