What Happened To Gnuplot?

Hi there. My environment is Ubuntu 12.04 OS. I have an example of the files I create with gfortran and gnuplot. The gnuplot draws this picture from a data file with 2D Cartesian coordinates. It is perpective projection. I need to color some parts of the plot (various lines) in different colors because some other details must also be drawn and I feel that the resulting network will be confusing. Gnuplot user manuals treat this subject but only in conjunction with lines drawn through a formula like sin(x), etc. I don't have that. All I have is columns of floating point numbers. Is there way I can draw lines of different color with gnuplot 4.6?

Thanks, - A.

Hi there. I have a problem installing the newest version of gnuplot which is 5.0. I downloaded it from this website (sourceforge): a source tarball. The Ubuntu 12.04 archive manager in my laptop placed it in the directory /home/alex/gnuplot-5.0.0.tar. I opened the directory/folder with a click and began reading manuals. The install procedure (read INSTALL.gnu) calls for issuing this command:

Quote:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
It is impossible to get to the directory gnuplot-5.0.0.tar via a terminal. If I type cd gnuplot-5.0.0.tar it says that this is not a derectory. If I omit .tar it does not recognize the name at all. I tried to rename it but after that I could not open it even with a click.

What shall I do?

Thanks, - A.

Chapter 17 of gnuplot pdf manual (Mouse Input) says "The x11, pm, windows, ggi, and wxt terminals allow interaction with the current plot using the mouse." I wonder if my Ubuntu 13.04 has any of those, if not, then perhaps the three terminals (Terminal, UXTerm, Xterm) I can invoke here, maybe they also have the same property? The proper term is: are they mouse capable? Thanks, - A.

Trying to work with gnuplot in Ubuntu 12.04 I run into confusing comments about binary vs. ASCII files. Take this as an example for instance. Looking for a good explanation I open this link. It is an outstanding sample of confusion and obfuscation. My own understanding is that binary is an executable file and ASCII is a source file. With gnuplot it is all upside down. I am confused.

Thanks,- A.

I am reading a gnuplot pdf FAQ. In section 3.13 it says: "This requires you to write contours into a temporary file using the table terminal." Then I google and all I get is terminal-table. It says: install terminal-table by applying this command:

Quote:
$ sudo gem install terminal-table
What is it all about? What is a table terminal? What is a terminal-table? It looks like terminal table is to print tables in a terminal, right?

Thanks, - A.

pl help.
very urgent

I am not sure what happened here, and I find it oddly disturbing that a Putty session from Window could do this, but here is what I did -

I was attempting to open a ssh redirect session from Putty command line on my W7 work PC to my home PC running Ubuntu 14.04. I've done this before with the Putty GUI and had no issues at all, but this time I was using cmd line and it never did connect. I ran this command:
Code:

putty -ssh -D 1080 -P 22 domain.com

The Putty window opened but never connected. I tried twice and when it didn't connect, I gave up and went back to the GUI. I connected with the GUI just fine, but after connecting an SSH session to my Ubuntu server at home, I noticed it was acting odd.

Long story short: It was in a "read-only" mode, saying the file system was read-only. I couldn't run apt-get update or even create a new folder in my Home folder or desktop. I remotely rebooted the machine and it never came back online.

When I got home I checked it, and it told me that Ubuntu had found some errors, and was asking if I wanted to correct them. I said yes and it took a short while, but then finally let me log back in.

After this, the box is about 90-95% back to normal except for a couple of odd things that I don't understand.

The main issue is that my Samba shared drives are no longer working. The fstab file looks the same and can connect to other machines, but nothing can connect back to the Ubuntu box. The folder permissions are correct also. I have a CentOS7 box, a Fedora laptop and a W7 box - none of them can connect to my Ubuntu box. I only run Samba and connect with it, even from Linux boxes, just to make it simple (since Windows is stupid and can't use NFS) - this has always worked in the past. Now for the life of me, I can't figure out why nothing will connect.

Is there a logfile or trouble-shooter I could look at it see what happened? It should be in /var/log somewhere, but I don't know where to start. SSH? Samba? The entire filesystem was read-only for a short while, so is there a FS or System log in /var/log?

I am kinda confused on this one, any help is appreciated.

Hi, please excuse any misunderstanding about the title.

I'm an experienced computer user, but not with Linux. As a matter of fact, even with Windows, I only do so much at the command prompt.

I am looking for a very fast (boot and etc.) Linux system, that has nothing more than a command prompt. No X-Windows. However, I would like to configure X-Windows immediately after an installation.

I noticed the LFS project. Very cool, but way too complex for me. It is exactly what I'm looking for, except, I would like the basic system to already be proven, maybe even with security updates.

The biggest most important thing is (ONLY WHAT I WANT). I don't want dozens of browsers, a hundred text editors, or any other cool or stupid open source or commercial software. I simply am looking for what Dos 6.22 was in Linux.

There are many distros. Can you guys help me pick one out that is light, secure and ready to be configured to run X windows or X-Free or Xorg, I'm not sure what the best is right now.

PS: I'm a linux noob, but I have had several decent installations of Ubuntu, and some experience with the command line, including compiling software, but still a beginner.

Hi there. I'm new to Linux. My son installed it. First, I was pleased. Then I was angry: we have three printers in the house. It was incompatible with them all (when I connected the printer, it did not automatically install it. Now I'm frustrated. I have been to sites to find out what version of Linux I have. I am not a techie. I worked out how to get into the black terminal screen. I worked out how to write the command uname -a and got the answer Ubuntu 109. I don't know what this means but I then worked out how to put a command in $ sudo apt-get install cnijfilter-ip4500series to install the printer. It asked me for my password. I entered the password I use to open the user interface when I turn on the laptop. No dice. I need to distribute posters this pm. I will have to spend more money, going into town to get them from there. Not great. Any help appreciated. Advice, guidance, kind words of encouragement....
