How to Add points on graph from a text File ?

Hello and Good Morning to all,
I have a text file with my data and i read them by using the Read From Spreadsheet File VI,i enter the path where my file is saved,read all rows delete the first row because i don't need it and my problem is that in the text folder i have specified date and time which i want to be my X axis in my Graph and Y axis to be the Vout that means i have to use a XY Graph ,below you can see my data:
Date        time              Vout
3-9-2012 7:45:37            2,35
3-9-2012 7:45:39            2,75
3-9-2012 7:45:41            3,15
3-9-2012 7:45:43            3,50
1) Is the text file format compatible with the input of the graph command?
I do not find a LabVIEW function which convert the “date” from the text file (example:3/09/2012 07:45:37) into a compatible format for X axis for the graph.
(Conversion from string format => into a “date and time” format)
Can someone please provide a code solution for this problem?

Some tips:
1) If you are adding or deleting stuff from a text file you need to write a new, modified file and then, optionally, do something like:
rename the old file to whatever.bak or the like.
rename the new file to the old.
2) Don't depend on System.out so much on a GUI application. For example if you get an exception use javax.swing.JOptionPane to display an alert (and show the message from the exception). You can write the stack trace to System.out if you want.
3) Don't muck about with calculating bounds for screen objects, let a layout manager sort it out. I like BoxLayoutManager for most things like this.
4) For bonus points do your IO in a separate Thread. Generally you don't want anything happening in an actionPerformed method which significantly delays it's return. The method should launch a new Thread to do the job, and disable the button until the Thread finishes.

How can I add random mail signatures from a text file?

I'm trying to add a different quote to every email that I write... is there a program or way for Mail to pluck and append a quote at random from a external file of quotes? (I'm not talking about the standard "Random" feature built into Mail.)
There must be one out there, but I can't find it. I'm using Snow Leopard and Mail 4.5

Hello,
Here is a running start on getting specific lines in the case lines starting with ComboBox. I took your data and placed it into a text file named TextFile1.txt in the bin\debug folder. Code below was done in
a console app.
using System;
using System.IO;
using System.Linq;
namespace ConsoleApplication1
internal class Program
private static void Main(string[] args)
var result =
from T in File.ReadAllLines(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TextFile1.txt"))
.Select((line, index) => new { Line = line, Index = index })
.Where((s) => s.Line.StartsWith("ComboBox"))
select T
).ToList();
if (result.Count > 0)
foreach (var item in result)
Console.WriteLine("Line: {0} Data: {1}", item.Index, item.Line);
Console.ReadLine();

How to import data into JTable from a text file?

thanks in advance!

My guess is you will have to read the data in from the file, parse it, populate some vectors or something and use those vectors to instantiate the JTable. You could use FileReader to read in the data:
FileReader in = new BufferedReader(new FileReader(file));then use StringTokenizer to parse it.

How to read every line from a text file???

How can i read every line from my text file ("eka.txt")
now it only reads the first line and prints it out.
What is wrong with this?
import java.io.*;
import java.util.*;
class Testi{
     public static void main(String []args)throws IOException {
     BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
File inputFile = new File ("eka.txt");
FileReader fis =new FileReader(inputFile);
BufferedReader bis = new BufferedReader(fis);
String test=bis.readLine();
String tmp= "";
while((bis.readLine().trim() != null)) {
int spacefound=0;
int l=test.indexOf(" ");
     for(int i=0;i<test.length();i++){
     char c=test.charAt(i);
     if(c!=' ') tmp+=""+c;
     if(c==' ' && (spacefound<1) && !(tmp.equals(""))){
     tmp+=""+c;
     spacefound++;
     if(tmp.length()==l) {
     System.out.println(tmp);
     tmp="";

     if(tmp.length()<l){
     for(int i=0;i<=(l-tmp.length());i++)

Average Data from multiple text files

I am new to labVIEW hence a little help is appreciated:
I have a 100 txt files with two columns (tab separated) for X and Y value.
I need to average the Y values to generate one single txt file and generate X versus Y graph.
So how do I read the data from these text files? (without having to select each one of them individually) and how to average the data and create a XY graph from it?
Thanks in advance
Solved!
Go to Solution.

Use X-Y Graph.
You were able to get two arrays of X and Y points from text file right?

Yap the row and column will change but i had already parse these lines into my code. However, i am still figuring on how to get the integer number 1,2,2,4 of the text file using while loop and not include the "</matrix>" in the reading. Can this be done?If the numbers you want are at fixed byte positions in the file that are known ahead of time, you can use java.io.RandomAccessFile to skip to those positions. However, that seems unlikely.
If, as is the more likely case, those are not at fixed positions, you'll have to read everything preceding them. (Note that this is not a Java issue. This is how file I/O works.) You'll need to ignore the lines that are meaningless to you (read those lines and do nothing with them) figure out, by whatever rules you have--line numbers, preceding tokens, whatever--when you're at the lines you do care about, and then read and process those lines accordingly.

How can I plott data from a text file in the same way as a media player using the pointer slide to go back and fort in my file?

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

How to add pdfs n movies from my PC without creating ne library

How to add pdfs n movies from my PC without creating ne library... Does iTune has ne converter tht can convert movie into format that iphone can play..

That's easy, while connecting the iPod to the computer on Windows with iTunes 7.3 installed hold down the Shift + Ctrl keys. This will stop the iPod from auto-syncing with iTunes and the iPod will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 20 to 30 seconds depending on your computer. If your iPod shows up ok in iTunes you can change it to manual from there.

How do I remove padlock icon from all my files?

On one of my drives, every single file has a little padlock icon superimposed over the file icon. I recall when I did a clean install of windows 7 RC over my Vista install, I wasn't getting write access to the drive so I had to take ownership of the drive and mess with the security settings before it started working normally.
I have to admit, I find the security settings in all versions of NT mystifying... For instance, although my account is in the administrators group, having full access to administrators never seems to work. I always have to add my individual user account and explicitly give it full access.
In any case, I can't remember exactly what it took, but after messing around with the security settings for a while, I eventually was able to have full access to the drive and have no problems reading/writing/deleting files and folders, but there's the padlock icon still on everything.
Can anyone explain how to get rid of it, and/or maybe point me to a good, clear, understandable guide on how to properly set NTFS permissions.
Thanks!
