Reading from a .txt and displaying in XY graph with time stamp

Hi,
I am a newbie to LAbView. I need to read from a text file having two columns, one carrying the temp value and other the time stamp. I need to plot this in XY graph on a real time basis. Please help as how can I do this..
I am attaching my files for your reference.
Thanks in advance

So what is the question about... I have to use XY graph in my program. It is used in Loop while cycle. It shows the statistic of a variable. I am using cursors in this graph to check the actual value of a variable in different period of time. But there are 7 variables and it is extremely hard for user to check each value independently. So I tried to make them moving on the X axis (TIME) together using the property node (cursors reading the position (only X axis, Y axis status lock to plot) of the major cursor and follow it... Everything looks great? But it did not work when I am trying to move the major cursor manually on graph... It works only when I am using the cursor movement buttons... But they work very slowly when there is a lot of data in graph.
I want to find out is it possible to make seven coursers mouthing together By the X axe and be Locked each at its plot by Y axe manually (Using mouse moving on a graph). Is it possible? If it is than how to do it?
Hello Shidla,
The attached VI should help give you an idea of how to create a VI that allows all cursors to move together. The main idea is to keep track of the current location of all cursors and move all of them when you see a change in one's position.
Good luck with your development.

How to read time stamps from a spreadsheet and calculate the difference between consecutive time stamps?

Hi,
I am new to Labview. This question might be a joke to some of you here, but any help would be greatly appreciated. I have a spreadsheet with time stamps and power outputs from a generator. I am supposed to calculate the difference between consecutive time stamps, which will act as a delay for the next power output update that needs to be sent. For example, lets say that I have to following data:
Time Stamp                    Power Output
11:00:00 AM                       3kW
11:00:02 AM                       2.9kW
11:00:04 AM                       3.2kW
11:00:06 AM                       3.1kW
The above data doesn't make any sense, but it is just for the purpose of this question.
So, I have to read 11:00:00 AM and 3kW initially - 3kW is the initial request that is sent. Then I have to

Read a text file and display a xy graph

Hi!
I am using LabVIEW 8.5, and I am trying to read columns from
a file and plot with xy graph. I can do it with two channels, but I am having
problems when the numbers of channels connected increase (maybe six or ten).
My text file looks like this:
[Where first column x = time, the rest of the columns are
channels = y]
8.828        22.604        23.076            [The number of channels connected can
change]
9.828        22.604        22.604
10.828      21.658        22.131
11.828      22.131        22.131
12.828      22.131        22.131
13.828      22.604        22.604
14.828      21.658        22.604
15.828      22.131        22.131
16.828      21.658        23.076
17.828      22.604        22.131
18.828      22.131        22.604
I attached a picture of what I already try… Now I am trying
a combination of those. If anyone has some
advice or suggestion, please let me know.

Thanks for the advice!... I just modified what I had a
little bit and it is working, maybe is not the optimums solution…
I would like to make the time invisible in the graph… It that possible? I attached a picture of my graph, because my English is not good. There are two lines near to 22 (two channels
connected at that moment), and a line near to 0 which is time (the strong pink one). I would like to make invisible the strong
prink one only. I try to make invisible,
but I fail… I changed colors looking for another solution and I fail again,
because it is taking the colors that I choose for the channels. I can not disable because I need it to make
the x axes works with the time that I already saved.
If someone has an advice or suggestion I really appreciate it…
Sincerely,
Julieta.

Read from spreadsheet and plot multiple XY graph

I'm trying to read a text file using the "Read from Spreadsheet" function. Next I want to plot the data in it on a single XY Graph.
The text file contains 4 coloums and the first coloumn is X axis and rest are for Y axis. I'm not able to get the multiple plots.
However, I could get it to plot when only a single graph is to be plotted(only 2 coloumn in file). I've attached my VI and a picture here.
I need help in plotting multiple XY graph from the text file with the 4 coloumns.

Trying to read a recorded file that display the x-axis recorded time stamp?

How do I read a recorded file with (XY) data, meaning I want to plot the x-time recorded data and be able to scroll back and forth.

Hi Gina,
If I understand your question correctly, it sounds like you are trying to plot some data that you have saved in a file. I am assuming that this data is in the form of X and Y values.
If this is correct, the easiest solution would be to use an XY-Graph in LabVIEW. I would start by using LabVIEW's File I/O VIs to load the data into an array or even a string indicator. You can then parse the data that you need and separate it into two arrays, one for X values and one for Y values. You can then bundle these two arrays together and feed the resulting cluster into an XY-Graph.
I have attached an example that may help to point you in the right direction when it comes to the actual programming.
I hope this helps!

"Ellie,
The first thing you need to do is to read your file in as a spreadsheet file. Then, you display it in a chart.
That sounds simple, but looking at your dataset, there's a few things you should know. First, the "read from spreadsheet VI" is looking for data in columns, like your data set, but columns separated by tabs. Therefore, your data must be saved that way; currently, it doesn't seem that it is. Another thing; you must skip the header portion (labels) of your file when reading.
Next, it would be easier if your time was first, and your data was second in your columns, but that can be overcome. In the VI I am including, I have copied your data set into a file called data.txt, and I've removed the header and separated the columns with a tab. Then, I read in the data, and I break out each column so I can put the time first, and then I combine them again into a cluster so it can be displayed on an XY chart.
Take a look!
Mark"

All you have to do is use Read From Spreadsheet File.vi that's on the File I/O palette. For your example .txt, set the Transpose input to true and wire the First Row output to a waveform graph. The only problem I see is that since your file doesn't contain any sampling info, the time axis will be relative. If have that information elsewhere, then you can put a build waveform function between the read and the graph. Wire the First Row output to the Y input Build Waveform and add t0 and dt values. I've attached an example.

Efficient optimized way to read from serial port and GPS data display using map

Hi,
I have a custom h/w which reads the data from GPS Rx and after parsing send it to PC over RS232.
Each second it sends 201 bytes to PC. I have developed a VI to read the GPS data and display it. Project file is attached.
Fulctionality of different loops are as following:
1. LOOP 1: 1.1 Reads the serial data from com port.
               1.2 Synclonize the frame using start bytes "a" and "z".
               1.3 Reads next 4 bytes containg receiving error information.
               1.4 Reads next 195 bytes. in which initial 80 byes are GPS data. rest are others.
2. LOOP 2: 2.1 Extarcts the GPS information and put them in an array.
                  2.2 Extarcts the receive error infor and counts the total error by incrimenting the variable using shift reg.
3. LOOP 3:3: 3.1 Displays the GPS data in chart and log the data in a file.
4. FLOW : Uses the GMAP .NET based API to creat a MAP and display.
Problem statement:
1. Functionality acheived.
2. However in between data set is being missed by the programm.
Quesitions:
1. Is the developed VI is efficient in terms of using queue loacl variables etc.
2. What are the improvments I can do to solve the problem.
Any other suggestions|
Thank you

One of the most common problems in serial communication is the need for an adequate timing: how much time is expected your device to spend before answering? Have you put and adequate pause in your code before reading from the serial port?

Trouble reading from serial instrument and DAq simultaneously.

Greetings,
I am having some trouble getting my VI to read from my DAq and a serial instrument at the same time. If I run the subVI's simultaneously (i.e. subANG is running in one window and subVEL is running in a second window) both return the proper values and behave as I would expect. However, if I call the subVI's into a parent VI and try to run them both in the same loop structure subANG gets stuck and will not resond with a change in signal.
I have also tried to use a stacked or flat sequence to separate out the execution of subVEL and subANG, but I still get the no response from subANG.
The most confusing thing is that if I run Parent.VI in one window and then create a copy of subANG (call it '....-copy' or whatever) and run it in a second window, Parent.VI behaves properly and will refresh the readings as they appear in '...-copy'.
I have attached 3 files.
(1) subANG.VI     -This reads an RS232 signal from an inclinometer. The signal is refreshed every 10ms or so.
(2) subVEL.VI      -This reads raw voltage from one channel on the DAq, calculates the mean then converts that into a pressure differential and finally a velocity based on the pressure and temperature inputs.
(3) ParentVI.VI     -This simply calls and displays the subVI's
My guess is that it is a buffer issue, but I am stumped. Does anybody out there in Labview land know why this might be happening? All suggestions welcom.
Solved!
Go to Solution.

I am noticing it is not an NI DAQ card. How are you communicating with the DAQ? If it is using a serial port, that could be your problem.
I also highly recommend using the VISA drivers for serial communications instead of the serial.llb VIs.

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. And then reboot your computer.
See if that fixes your problem.

Hi,
According to your post, my understanding is that you wanted to search result to get data from bing search and displayed it in sharepoint page.
To display more items, you can modify the item number when you add
New Query Rule.
To get all results, I recommend to use the “Show More”
link in the result page.
You can enter the URL when you add New Query Rule:
"More" link goes to the following URL: http://www.bing.com/search?q={searchterms}
