• selection of data for analysis

  I have an additional column of measures of conductivity at intervals of 1/10 s. In preparation for the analysis of the data I isolate each individual tournament that starts when the dyeing point is introduced into the system, the pulse then goes to the measuring device and conductivity registered values increase until they peak and then decline down once again. Finally, the event "ends" when the next pulse is introduced. The problem is that the entry of dye time was not at regular intervals, so are the tails of events of different lengths, so I need to truncate the data in a more systematic way.  I want to truncate the data at a point after the Summit, somewhere in the tail when the average of the 5 consecutive values are< 0="" (i="" need="" to="" specify="" after="" the="" peak="" because="" sometimes="" negative="" values="" occur="" before="" the="" peak="" and="" i="" need="" to="" keep="" this="" information).="" i="" think="" using="" a="" while="" loop="" and="" running="" it="" until="" the="" criteria="" is="" reached="" is="" the="" way="" to="" do="" it.="" but="" i="" am="" not="" sure="" how="" to="" structure="" my="">

  PS I'm using Labview 8.6

  How about something like this? I'm not so he can go below 0 five times instead of that I find the peak value and then seek to cross the line of the zero down. You can do more complicated if you wish.

• How to build a table of measured data permanently

  Have a good day for everyone,

  I have a problem about the construction of a table permanently. I tried to find the solution for a long time, even if it's a task really simle.

  I want to build a table permanently, virtually:

  I like to read data from a measuring devices and I would like to sotre it one by one, at all times. I made a simple VI to present one where my problem is. The random generator represents the data given the measuring device.

  At currently I am able to store data only 1. When I want to store then that it is crushed.

  Thanks for anyone who can help me.

  Hi LIG.

  no need for a structure business when you can use autoindexing:

  

  Also, the code snippet shows how to convert a number in your reading string. You probably prefer tanks instead of integers...

• How to build a table of TDMS file open

  Hello

  Examples NI TDMS - Express write data .vi (time domain), I can build a PDM file with 2 channels (sine and square waveforms) data, which are stored as test.tdms.

  Using Express read .vi data (time domain), 2 channels of waveform data are read. How to build a table later? How to separate the 2 channels of data in the tables 1-2 and manipulate the data using table functions?

  For example,.

  I want to collect 100 from index100 between channel 0 and their average. I want to take 50 samples from the channel 50 1 index and double each element.

  Thank you for your help.

  Bing@NCL

  Hey Bing.

  You can perform operations on different channels in the 2D table using the table to index. This will allow you to choose the channel to operate on, then you can perform the operation inside a loop on each element. In the included code snippet, I used a shift register to find the total cumulative values in channel 0 and then divided by the number of samples.

  I recommend you read some tutorials LabVIEW and bases of knowledge on topics that are related to yours. These could help a lot.

  I hope that my suggestions help,

• build the table when values change at run time

  Hi all

  I have a continuous stream of frequencies that continue to change during execution. I need to make a table of these values. I use the array build function. This option stores the first value only and the order of the day replaces the stored rather than settle down after that. I was going through the examples of labview and I think that by using the shift register can somehow solve this problem. However after an hour of futile play with lag, while loop records and build blocks table that I decided to post on this problem. I would like if someone can delete my concepts as well as a solution. The conceptual linkage is for what the first value to maintains have replaced. If I use the table of generation block the values that come should then fill the following vacant location logically. Instead, it replaces one only.

  You are right that I have simply the case that I warned the first sentence.

  Other methods require a certain amount of planning on the structure of data-handling. It is suggested at least...

  A better approach would be something like a circular buffer where you initialize an array of the desired size (for example 10000 items) and then start to replace the items. You can use the iterator of the loop you have to 'reduce' using quotient & reminder (which is the 'modulo' mathematical operation).

  hope this helps,

• How to build a table in a master/slave relationship?

  Hello NOR community,

  I can't build a table in a master/slave relationship. I want two paintings to be built for a fixed amount of iterations, once press the 'pressurization '. (This data acquisition would occur only once per program). I am new to Labview so I apologize in advance for my layout disorder.

  I want the slave program to create two tables and analyse the slope of pressurization to arrive at the same time as the master's program and the master program to continue to acquire data of pressure.

  Master slave relationship is even necessary here? How to pass a variable (pressure main once a loop without getting stuck in a nested loop situation?

  Here is a small example, just to show an idea (many things is not optimal in this example!). Based on your VI you have attached, you miss a lot of basic concepts of LabVIEW, you go through online training.

  

• Build a table or merging of signals?

  I know that there is more than one way to merge waveform signals to display in a waveform chart. The two that I know are a fusion signal express vi and build the table. But I was wondering which of the two were more effective. I read once somewhere in this forum that this "generation" is one of the tasks much more time.

  Not very critical of what I'm doing (a data acquition loop takes a few milli seconds with table generation) but was just wondering if one or the other has a better way to do it. Or it could both be the same.

  Thank you.

  If I understand correctly, you only build a piece of data in an array of 1 x 1 each time through the loop.  If this is the case, then there is no problem with the way you use table build and build waveform to get your data on the graph with the timestamps of law.  It is perhaps not the most effective approach, but at a rate of 200ms update, you are unlikely to have problems.

  Build problems when you add constantly in an existing table because the table maintains more and needs to be reallocated whenever a new item is added.

• How can I write time to build the table in just a few seconds?

  Hello world

  I am able to use "elapsed time" to send a time stamp to "build the table" using the output of 'elapsed time to text.  But after 59 seconds, it gives then a minute.  In the excel file, it is as follows:

  0 00:00:59

  0 00:01:00

  0 00:01:01

  I want to continue to 60, 61 seconds and so fourth.  When I try to connect to an another Subvi, it gives me a connection error.  Any help would be greatly appreciated?

  Thank you

  Ferriol

  I guess that's the Express VI, you can use the output of the time elapsed (s) instead of the number of seconds passed.  If you want a string, use the Format String VI, or build an array of DBL to add to the rest of your data.

• The table of hash of the dates

  Hello.  I have a table of hash on the dates and phone numbers (string/integer).  I need a loop through the hashtable and get the sum of the values for all the keys that fall between 2 dates.  Not sure how I'm going to address the issue.  What is an effective way?  I think something like what follows however not sure it's the right approach...

  Keys enumeration = theHashTable.keys ();

  Elements of the enumeration = theHashTable.elements ();

  Key of type string;

  Integer value;

  {while (Keys.hasMoreElements ())}

  key = (String) keys.nextElement ();

  value = (Integer) elements.nextElement ();

  somewhere / somehow thrown string date as long to compare/verify if this key is between a range of dates and, if so summarize values

  }

  Any suggestions on an efficient way to achieve this?

  For me, this is not a very large number and thus probably justifies no complications.

  I would design your data structure to optimize the use of the most active and then do all the rest by brute force.

  So if your use is going to be mainly the extraction of values between two dates, and then use a sorted vector, sorting manually if you think that it's easier and do a search sequential or same binary to find the values associated with a date specific.  If you're always looking for dates, then stick with the hash table and then enumerate over it to the value of a total range.

• Data for random table Gahering

  I searched the boards for help on this and do so taught me SOME of what I have to do, but not all.
  
  I think I can build a table now, but what I need to know how to do is to COLLECT the data for the table of user-seizures of text, then having Flash back a # of random inputs.
  
  That's the drug testing. I have to be able to enter the names of the employees (collected by the table) and then enter the number of employees, I want to have tested (say 6 of 20 names entered). So I want the Flash to give me 6 of these names randomly without duplicating.
  
  As I said, the research here, I think I learned to build the array by using the dynamic text boxes. What I didn't know is how to return X number of these data to the user randomly.
  
  Any ideas?

  Once you have a table, you can mix it and then just count however many elements you need.

• Unable to display data for the date where there is no entry in the table

  Hello
  
  I need a urgent, described below:
  
  I have a table named as 'dirty', consisting of three columns: empno, sale_amt and sale_date.
  (Please ref. The table with data script as shown below)
  
  Now, if I run the query:
  "select trunc (sale_date) sale_date, sum (sale_amt) total_sale of the sales group by order trunc (sale_date) by 1.
  It then displays the data for the dates there is an entry in this table. But it displays no data for the
  date in which there is no entry in this table.
  
  If you run the Table script with data in your schema, then u will see that there is no entry for the 28th. November 2009 in
  sales table. Now the above query displays data for the rest as his dates are in the table of the sale with the exception of 28. November 2009.
  But I need his presence in the result of the query with the value "sale_date' as '28. November 2009 "and that of"total_sale"as
  « 0 ».
  
  Y at - there no way to get the result I need?

• Create table with several Collections of data control

  Hello

  I have a requirement about to display data in a table. It shows simple, but certain columns in the table are within a collection, and the others are in another collection. I read this chapter Creation of ADF Databound Tables - 11 g Release 1 (11.1.1.7.0), and she explains to create the table with a collection.

  I have no knowledge on the model, I know just as control data, so what should I do? :

  -Ask for the template designer to redraw the control of data to include a collection with all the data?

  -Try to work with the actual data control? If so, how can I create the table several Collections of data control?

  Plese let me know if there is another solution. I work with JDeveloper 11.1.1.7.

  Thank you!

  Hello

  You can have a managed bean that e... g exposes an ArrayList of objects. This can then binds to the value property of the table. If the object sets the information of table row combination that you get multiple iterators (collections), then the table will display the joined data.
