How to plot a graph from text file?

This is driving me nuts!
I would like to plot a list of numbers in a text file to a graph. Each munber is on a new line, like this -
345
356
378
379
345
etc.
I managed to import the file and split it with the 'Spreadsheet to array' function but can't get much further than that.
Help would be much appriciated.

You just need to use the Read From Spreadsheet function and wire a 'True' to the transpose input. Wire the 1D array output to a graph.

How to find largest number from text file

I am using the "Read from text file" block to read the data from my .txt file into labview. It is now in string format. I have many numbers in the file.
For example:
0.45
0.35
0.12
1.354
1.56
2.89
5.89
0.56
That is what a text file might look like. I want to find which of these numbers is largest, and do calculations with that number. I am having trouble with strings/number formats/arrays, etc. Thanks
Solved!
Go to Solution.

The spreadsheet functions and VIs typically work on strings representing numbers separated by delimiters. This is a typical way to save a "spreadsheet" (of numbers) to a text file, for example .csv files. These are quite versatile and powerful functions. Spend a bit of time becoming familiar with them because you may find yourself using them a lot.

Continual plotting of data from text file

I would like help with automated plotting of multiple sets of data on one axis. The file attached shows a sample of the data where the first number (eg 405) is the reference and the next two are the date and time. The data after that all needs to be plotted in a different color. The A.A.. (or .....) does not need to be plotted, the N/A's can be assumed to have either no reading or the same as the previous day. The data needs to be read from a text file and then graphed. The sample shows only a few variations and the reference number is incremented by 1 (I have shown random data) everytime the data is obtained from the source. Is this possible. If it is possible, the system will then need to be expandable to be able to updat
e the graphs daily as the new data is obtained (although this is not so important at the moment). Can anyone please help me with detailed instructions if possible. All help will be greatly appreciated.
Thanks

I have written a rough vi for you in LV 6.0. Basically it shows how to open a file and write the string to an indicator. Then create an array from the numerical parts of the string which are plotted in a graph. I have assumed that the date/time and ref numbers will always be of the same format on each line of text.
I'm not sure if i have done exactly what you want, but should give you an idea of what to do. Let me know if you have any problems..

Convert a line read from text file into string

how to convert a line from text file into string?
i know how to convert to numbers,
private int parseLine1(String line) {
          StringTokenizer tokenizer = new StringTokenizer(line);
              value1 = Integer.valueOf(tokenizer.nextToken()).intValue();
              value2 = Integer.valueOf(tokenizer.nextToken()).intValue();
             return value1;
                 }but what about charactrs?

ok, here is my problem, i have a file with a bunch of Xs in it but position function doesn't return a correct value, what's going wrong?
private int positioni(){
       int i=0;
       int j=0;
       int b=0;
       String line="";
        while(line!= null){
            for(int a=0; a<line.length(); a++){
                if(line.charAt(a)=='X'){
                    i=a;}
            b++;
            j=b;

Read from text file and plot in real time

Hello to everybody,
I recently started using labview and so I know very few features, I apologize for any crap I'm about to write.
My problem is as follows:
_ A wireless node is sampling, with a known frequency, the voltage and the current of an electronic device
_ These data are sent to a coordinator connected to the PC
_ Each packet sent includes a single column with: Letter V followed by voltage samples, Letter I followed by current samples (all in a single column as in the attached example)
_ The coordinator saves it in a .txt file
I want to do a labview application that:
_ Reads that file (continuosly update by the coordinator)
_ Plots on two different graphs the values (over the time) of current and voltage
Thanks for your help
Danilo

There are File IO examples that ship with LV which show you how to write to red from a file . A more fundamental question though is why have the file at all? Is it serving strictly as a data communication channel, or will it be used for something else?
The "coordinator" that you mention, can it be accessed directly? Serial IO? TCP/IP? Telnet? ActiveX? .NET? Anything?
If so, that would be the preferred way to handle this situation.
Mike...
PS: Sorry for the next bit, but I used to be a magazine editor and my grandmother was a school teacher so I am just a tiny bit anal retentive about word usage: In English "data" is a funny word in that while it is a singular form, it is (depending upon context) often understood to referring to multiple things and so can be sort of plural. Consequently, it is proper to say: "This data is sent.. " or "The data indicates...", but not, "The data are showing..". Likewise it is always incorrect to try to make it plural by saying "datas".
PPS: The same goes for the word "code" when used as a noun. It can also be a verb, but that's a whole different rant...
PPPS: Also be aware that many of the people who know me well would object to the "tiny bit" part...

How to open saved files using 'read from text file' function

Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?
Here are some screenshots on part of my program
let me know if you guys would need more information / screenshots thank you!

Ohmy, thanks altenbach. oh yeah i forgot about those sub VIs. will upload them now. Was rather demoralized after reading the comments and really struck me on how weak i'm at on labview really hope to get this done. But of course i have to study through and see how it works. Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.
( ps . cant connect it now unless my program is working otherwise labview will crash )
( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )
The sample code of ThoughtTechnology is named as attachment.ashx.vi. too bad i cant use it and present it as my project

How to create PDF from text file with specific layout?

I wanted to create the pdf from text file in specific layout - Landscape orientation and JIS B3 Page size while at Adobe Acrobat Pro.
In past, I could do a right click on a text file (desktop area) and select print to print out the document into .pdf BUT only if I set the Adobe PDF to Landscape and JIS B3 Page size BEFORE. And I could only do 15 text documents at once.
I wanted to see if I could do the create the pdf from text file with specific layout in Adobe Acrobat without having to go to Control Panel to preset the Adobe PDF to specific layout at every time. I would have to set Adobe PDF back to normal layout after I'm done with these pdf print outs. I do lots of pdfs in normal layout. Sometimes I would forget to do that.
So, How do I do that?

No such luck. It would output the contents in letter size even in JIS B3 Page layout at MS word.
Is there a script or action where I could set the orientation and page size before creating PDF on these text files?

Where are these unix executable files coming from and how do I recover the original text file?

where are these unix executable files coming from and how do I recover the original text file?

When you upgraded to Lion did you have AppleWorks installed on your mac?
Most of the AW documents can be opened by Pages 09 or Numbers 09 with most of the orginal format in tact. (I do not know if previouse verision will work) just open the AW file with both and see which one works best.
Text Edit will also open most of the AW files as well but will require a lot of work to restore them to their orginal format.
If you have AW Database documents then they are not supported.
These document show up as "exec icons", Kind: Unix Executagle File.
They also will show up as .cwk file if they are small files. I have a couple that were under 1mb that are shown as " Kind: AppleWorks Document" but will not open.
The only option to open AW database is to have AW installed on a mac with a pre-Lion OS to recover the file.

How to plot waterfall graph in vb6 from offline data

How to plot waterfall graph in vb6 from offline data?The data load from SQL Server Database.Thanks.

asrol,
If you look at the Plot Styles example in the folder I mentioned in the previous post there is a section of code there that you might want to refer to in order to recreate your data.
'=============================================================================
' Plot Curve Button Handler
'=============================================================================
Private Sub PlotCurve_Click()
    ' Create curve data
    Dim x(40)
    Dim y(40)
    Dim z(40)
    For i = 0 To 40
        x(i) = Sin(i / 3#)
        y(i) = Cos(i / 3#)
        z(i) = i
    Next i
In this example they create 3 arrays to represent the three dimensions of the array. For your case if you were to plug your data into two of the array (axes) that would give you the data for the channels, then you can simply input a constant for the third array it would produce a single line of your data as shown in your example GIF. You can then repeat this process for each set of data, with a new constant value for that third axis, and it should manually create a graph that will look something like you desire.

The standard Excel Insert Graph.vi cannot insert multiple XY Graphs to Microsoft Excel, so you will need to use the Report Generation Toolkit for Microsoft Office. You will find a link to an example program at the bottom of the page. I have also attached it below.

How can we read a column from text file

hai,
the Text file contains :
m1 m2 m4 89
m1 m2 m4 89
m0 m4 m2 90
I need one array for each column
m[0]= m1,m1,m0 (first column from text file)
m[1]= m2,m2,m2 (second column from text file)
m[2]= 89,89,90 (third column from text file)
andvance thanks

If a 2D array is OK (instead of 4 separate arrays), try something like this
import java.io.*;
import java.util.ArrayList;
class FileReadColumns
public static void main(String args[]) throws IOException, FileNotFoundException
    String line;
    ArrayList lines = new ArrayList();
    BufferedReader in = new BufferedReader(new FileReader("data.txt"));
    while ((line = in.readLine()) != null) lines.add(line);
    String bits[];
    bits = lines.get(0).toString().split(" ");
    String grid[][] = new String[bits.length][];
    for(int i=0;i<grid.length;i++)grid[i] = new String[lines.size()];
    for(int i = 0; i < lines.size(); i++)
      bits = lines.get(i).toString().split(" ");
      for(int ii = 0; ii < bits.length; ii++) grid[ii] = bits[ii];
for(int i = 0; i < grid.length; i++)
for(int ii=0;ii<grid[i].length;ii++)System.out.print(grid[i][ii]+" ");
System.out.println();
System.exit(0);
