• How to add corresponding elements of two arrays in a continuous acquisition?

  Hi all

  I am writing a program (in version 9.0 of labview) to acquire the signal of a fast set. I use the acquisition rate of 1.25 Ms with an external trigger. Now what I need, is to add the "n" data these acqisitions and then further process.  E.g. If I signal to 200µs acqiring can total number of data points with the acquisition of 1.25Ms rate will be 250. I'll get a table 1 d of 250 data points whenever I run my acquisition.

  Let's say Array 1of acquisition number 1, 0.1, 0.3, 0.5, 0.6,... up to a total of 250 data points

  Table 2 of the acquisition by number 2, 0.4, 0.5, 0.8, 0.4,... up to a total of 250 data points

  ----------------------------------------------------------------------------------

  Added table should be 0.5, 0.8, 1.0, 1.3... .route to a total of 250 data points

  -----------------------------------------------------------------------------------

  To do this, I need first to save the table of acqisition number 1, then run the No. 2 acquisition and add points of data corresponding to the saved table. This should continue at a nuber defined by the user to purchase say 10, 20 or 50... I don't know how to do it. Can someone help me with this problem?

  Thank you very much in advance

  Kind regards

  I guess that time avarages and acquisition will not change during the measurement, so keep a cela outside loops. If you know your settings for made her make it constant.

  you create task (outside the loop) and a narrow at the end.

  Avoid the dashboard generation where possible. With no.. AV., and no. acq.points declared, the size of the arrays is fixed and you can (re) use a single Bay and replace the elements in the array.

  No need to collect all the data and avarage them after the rally. Just add

• How to use the elements in the array

  Hi, I am trying to automate a questionnaire using table.

  In the compositionReady for the scene

  SYM. Actual = 0;

  sym.arr = ['Hi', 'Love', 'You'] / / this is my picture of the issue.

  sym.checkArr = function() { / / this function I use to check the issue table whis I'll use.}

  sym. Question = arr [real];      I want to use the value 'Hi' and then increase my 'real' var and then use the value 'Love '.

  }

  In my symbol calendar, I use a trigger in the trigger that I use

  SYM. Stop();

  sym.quest = sym.getComposition () .getStage (). Question; / / I get the value of the Question;

  Sym. $("Ask") .html (quest);                                                        "Ask" is an empty textfield;

  sym.getComposition () .getStage (invested) ++;                    Increase 'real' for the nex time.

  But the code does not work, I think that the problem is the way I use the array index.

  Help, please!

  Thank you =)

  at the outbreak of timeline you why did you use a local variable?

  It is advisable to use local variables when possible. The quest variable apply only to this trigger, and it will not be postponed to another trigger in the same timeline. So when you use a trigger to set the HTML for a text element in the same timeline, I find cleaner to assign a new value of a local variable HTML.

  and if you call the 'real' global variable of Manager compositionReady of why didn' there you call him with all the way like ' sym.getComposition () .getStage (invested) ++; '?

  I think I have didn't express it as clearly as I could have. When you declare sym.actual in compositionReady, you actually declared a variable whose scope is the symbol of the main stage - it is not a global variable. To declare a global variable (which is not always recommended), your code in compositionReady would be:

  real = 0;

  This real variable would now be accessible from any element/symbol in the composition simply by assigning a value to the membership. You can see how quickly this could be embarrassing.

  So back to the scope of variables: If you declare a symbol variable using sym.varName, any element in the same scope may call using sym.varName. If your main scenario triggers can call without using the full address of sym.getComposition () .getStage () invested ++. Instead, you can simply use ++ sym.actual. Less code and easier to read. But if you call from another symbol (outside), you need to use the full, addressing the address actually the variable, i.e., sym.getComposition () .getStage () invested ++.

• How to add an element to an array, and then be able to remove more precisely

  So, I have a list of numbers. The user can then add numbers to this list. I have a button that allows the user to remove any number of their choice by typing this number in a text box. For some reason the numbers that the user adds to the list will not disappear once selected, while the original numbers go without problem.

  The name of the table itself is mesEntiers and the name of the TextBox: IntegersIn_txt

  Here is the code:

  function supprimer(event:MouseEvent):void

  {

  var indiceChiffre:int;

  indiceChiffre = (mesEntiers.indexOf (IntegersIn_txt.text));

  The indexOf method returns the index of an element or - 1 if not found.

  trace ("testBtn")

  If (indiceChiffre! = - 1).

  {

  for (var i = indiceChiffre; i < mesEntiers.length; i ++)

  {

  mesEntiers [i] = mesEntiers [i + 1];

  trace ("test")

  }

  mesEntiers.pop ();

  }

  } / / End of function remove.

  Two things I can think (I ran a small test)...

  (1) make sure your textfield is a single line, multi-line not... multi-line end up with additional stuff in them that you can't see.

  (2) convert the text to a number unless the table is now strings... indiceChiffre = (mesEntiers.indexOf (Number (IntegersIn_txt.text)));

• How to remix the elements of an array

  Hello

  My question is I have a table a = [0,1,2,3], and I want to get a table b with elements of a distributed randomly. I tired the below code but it does not work

  var a: Array = new Array();

  a = [0,1,2,3,4];

  var b:Array = new Array();

  4 = b.Length;

  b [0] = math. Floor (Math.Random () * 4);

  for (var i: int = 1; i < b.length; i ++) {}

  b [i] = math. Floor (Math.Random () * 4);

  for (var j: int = 0; j < b.lenght; j ++) {}

  {while(b[i]==b[j])}

  b [i] = math. Floor (Math.Random () * 4);

  }

  }

  }

  The code does not work. Smbd can help please.

  Thnx...

  Something like this should work:

  var Tester: Array = new Array (1,2,3,4).

  var randomArray:Array = new Array();

  function randomizeArray(array:Array,newArray:Array):Array

  {

  While (array.length > 0)

  {

  var obj:Array = array.splice (Math.floor (Math.random () * array.length), 1);

  newArray.push(obj[0]);

  }

  return newArray;

  }

  randomizeArray (test, randomArray);

  trace (randomArray);

• How to order the elements of an array?

  I m trying to elements of order in a table. When the dates come from dinamic text it s no problem, bad when come input text dates are treated as strings and it s imposible to order correctly, because 15 is considered to be less than 3. In both cases I can operate this date as numbers. ¿How is possible to order that this date of text entry, as the numbers of Pentecost?

  Thank´s

  textfields values are strings (even if it looks like a number to you).  There are several ways to handle this, and we need to get this string as a number before you add it to your table:

  My.push (Number (yourtextfield. (Text));

• How to select an element of a list with a separate button item

  This is a repost, I decided it would probably be better here than in the General discussion Forum. I will try to remove it.
  
  Hi all
  This is my first post here. I'm trying to find a way to select an item in a list with a button element. This button calls a function. I searched for the last 3 hours online and I can't find anything about it. I thought that maybe I could together the selectedItem parameter, but which is read-only and I think it returns an object rather than something like a number reference, so even if I could put it, it would be useless. I also found a button of update of get, thinking that can lead somewhere, but I think it's to define which element has the focus currently insofar as grasping and things like that. I'm lost.
  
  Basically, I'm looking for a way to type this myList.setSelected (5); where 5 is the 5th item in the list.
  
  Any help would be appreciated.

  

  Never mind found. It's called selectedIndex property and it is writable

• How to extract the value of the element as an array in javascript

  Hi all
  
  I want to do some calculations on the value entered by the user in the textfield of a tabular presentation, how can I retrieve the value of the element as an array in javascript?
  
  I use as a normal, do not use in the form of apex_item.
  
  I can pass the current value of the textfield to the function using 'this' as a parameter, but how can I retrieve the value of other lines of the same column?

• How can I view all the elements of an array?

  Hello

  I'm learning about the handling of tables.  The example finder includes this one, 'build array_forum.vi', which shows the two modes, concatenate and adding, I understand, HOWEVER, I can't understand how they built this vi.  For example, I can find the Array function to build, but I do not understand how they created the "digital data table 1" "data table 2" digital... etc, and I can't find the functions on the pallets that cause display "build the CONCATENATE entries table". ".  Where are these blue functions?

  Where these functions are found in the palette, and how we build them like that?

  The other vi indicated here, 'for loop array_forum.vi' is my attempt to reproduce, but it doesn't show all the elements of the array; However, it only displays a SINGLE element, the last element of the array.  How can I view all the items in the table I am creating using the FOR LOOP?

  Thank you
