• Average values for separate sets of data graph XY multiplot

  Hello

  I'm using Labview 2010 and I'm a bit of a novice, unfortunately.

  So I am currently trying to get average values of the three plots I have on a multiplot XY Chart. I thought the best way to achieve this would be to use the express VI of statistics, but when I try to wire the data I need for this I can get statistics for a set of data and not the other two.

  I don't know how the separately on data sets, as it is not a table.

  If anyone can help me, it would be much appreciated. Sorry for the probable simplicity of the question.

  (The program is basically an ODE Solver, which then displays pressure at different places in a bioreactor).

  In the small LOOP where you have data of y for each parcel in the form of a 1 d table, add a "mean.vi" in the math palette: statistics. AutoIndex the output on the edge of the loop to get a table 1 d containing three ways.

  (In addition, a lot of your code could be considerably simplfified. You can [i] connect directly to the structure of the case and a case of '0' and the other, by default. Better would simply initialize the shift, no means required register. Index table is resizable, so you don't need to a single instance on the lower right corner. Wouldn't be easier to just get the latest column and it wire back the entrance inside the structure cases via the feedback node? No need to "subset of table to replace").

  You have forgotten to attach a Subvi, so we can't really test.

• Calculate the average value

  the data that I measured changed quickly, so I want to get the average value of the data

  Don't tell me to use mean.vi, I already know.

  and I got an idea that is to add data in a table every time, then the sum of all value data and take the line of result by the number of items

  but I don't know how to do this, anyone can build a simple vi to show me? Thank you

  I enclose my vi that uses mean.vi to the average value of calc, you can remove it and help in your path, thank you!

  Do not add your data in a table that grows forever. What a waste of RAM. To calculate the average, you only need to sum and N.

  Here is a simple code to accumulate the sum of the values in a shift register and divide by the number of add operations.

  

• Problem adding values to a table with the state machine architecture

  Hello

  I currently have a problem that I have to build a program using state machine architecture and now I want to add a value in a table whenever you press a button, but I would like the table to add the new value, rather than deleting the last value. I can't seem to figure out how to make this work without using while loops and similar. It doesn't seem to work properly.

  It is in the case of measurement.

  The idea is I draw several lines then it records the length of the lines in a table and then I'll take one average this so I can convert pixels into real life SO units. But right now I can't seem to add the information in the table.

  There is a little screw Sub, but I think that they should not be important for this question please!

  What's the problem with just the table help build?

• Average values of several 2D arrays

• calculation of the average value of the sorted data and polar route drawing

  Hello

  I did a VI that calculates the average value of the wind rotor/speed-ratio in the sections of 30 degrees (wind direction). He also called the polar plot of calculated data. Everything works, but I would like to make more detailed calculations and drawings, by increasing the resolution to 1 degree, or...

  Problem is VI, I did, is not easy on a large scale. At the moment, I have 12 parallel structures of switch-box to calculate the average value and build the array function to collect data calculated for Polar plot to draw the image in real time. I know it's probably the worst way to do it, but since I have done a few things with LV, it was the only way I managed to do what I wanted.

  Now, if I continue in same way to reach my goal, I have to create 360 Parallels switch-case structures... that are crazy.

  Something like the calculation of the average of the table or matrix (zero/empty values should not be calculated on average) inside the loop or similar way would probably be the best solution.

  So, polar plot drawing is not a problem, but creating a reasonalbe average metering system is. Any ideas?

  I would also like to rotare northward to the top (0 deg), and degrees of increase in a clockwise direction on polar ground dial plate (as on the compass).

  I have signals:

  -Wind speed

  -wind direction

  -Rotor speed

  I want to:

  -calculate the average value of the speed of the wind / rotor - ratio in sections (5 degrees, 1 degree)

  -Draw a polar path of the wind rotor/speed-ratio of averages in propotion of wind direction

• acquire a signal and the rms value in a table every second

  Hello everyone,

  Sorry, but I am known in the world of LabView and I'm going crazy because I can't understand how to do a simple thing (or what it tends to be in my mind).

  As said by the object,
  my wish is to acquire a digital (a through the DAQmx) continuous (it's ok for this part), get the RMS (or average) of such acquired signal (thanks to the Amplitude and levels of measurement, for example) and put the value in a table (1 d); and, every second.

  In one sentence: acquire a signal, the average value, put in a table, and then restart each second. In the end, for example, the program for 1 minutes gives me 60 value in the table.

  Is someone can help me?

  Thank you in advance.

  Viviogs.

  First of all, I'm not sure that you can be sure exactly a second measurement using this technique.  If the precise timing is important, I think that you need a timed loop.

  That said, if the only problem you have is how to write the table indexed in a spreadsheet, you just need to use "Write in the worksheet file."  See here.

• Average value in a second a series of signals from the DAQ card

  Hello

  I'm trying to average signals in one second of my DAQAssistant.I am using a shift register to add all signals in a second interval and then dive out of the turn register by the number of iterations of my time loop (which I think should be the total number of samples per second-1). But when I studied the value of i from inside while loop by placing an indicator it always returns a value that is equal to my (sampling rate of DAQAssistant) / Samples as follows. This means that the average value I get something wrong, it is the average value seems within the reach of the signal I get.

  I wanted to use an array to store all the signals in a second, but I might have to increase the samples up to read the value in this case it will not be a very efficient way to store 500 data in a table.

  Any reclassification help how to get mean value over a cycle would be greatly appreciated.

  Thank you

  This is because an iteration of the loop returns a type of dynamic data that is under the hood an array of 100 samples.  The loop runs 10 times because you stop the loop after 1 second, only lasts only 1/10 of a second because she the 1000 Hz divided by 100 samples.  That's why I + 1 is equal to 10.

  Now you have 10 bays (buried in the dynamic data type) added.  Divided by 10 gets you the average of these 10 tables.  But this average is always an array (buried in DDT), but when connect you up to the average indicator, is to return only the first sample of average average array which is why your average seems essentially functional.  However, the averages of the other 99 data points (x iterations of the loop 10) are lost.

  You would be better off away from the DDT.  Just work with arrays.  Add the 10 tables to each other.  Now, you'll have an array of elements of a thousand that you can all wire to the average function in the range of statistics.  You won't have to worry about count the iterations of the loop, in summary and dividing.

  

• exclusion of a calculation of the average value

  Hello people from Adobe,.

  I am trying to exclude the "NC" 10 value are used to fill an average value (average rating of text box) on a form, I created.  I used the script from another topic on the exact topic thread, but I modified to fit my needs.  I think that it is a quick fix very.  For some reason, I don't get the average of all 10 drop boxes in my text box.  Can someone check this script and see what I might be missing.  The text box displays '0' because of this line event.value = 0;

  What Miss me?

  Here is the code:

  Average values of non - NA;

  var aFieldNames = new Array ("ListeDéroulante1", "Dropdown2", "Dropdown3", "Dropdown4", "Dropdown5", "Dropdown6", "Drop-down list 7", "Dropdown8", "Dropdown9", "Dropdown10");

  counter to the values non - NA;

  var nCount = 0;

  variable for values of sum of non - NA;

  nSum var = 0;

  default value of result if no average not calculated;

  Event.Value = 0;

  Table of process of domain names;

  for (i = 0; i < aFieldNames.length; i ++) {}

  If (this.getField(aFieldNames[i]).valueAsString! = "NA") {}

  field doesn't have a value of "NA";

  nCount ++; incrementing counter

  nSum += Number (this.getField(aFieldNames[i]).value). Add the value of the sum

  } / / end of value not of NA;

  } / / end of treatment a loop field;

  calculate the average;

  If (nCount! = 0) {}

  divisor of zero, so we can calculate the average;

  Event.Value = nSum / nCount;

  }

  I noticed that there 'Dropdown 7' as opposed to 'Dropdown7', which is what the field other names are similar. Could this be it?

• Inserting in a Table MYSQL Via Air/PHP unauthorized =?

  I have a problem inserting data in my mysql database tables through my air application. All the code is pretty much exactly the same as in some examples I've seen, but it will not simply do it. Is it because of some kind of restriction of security because the air application is on my computer and the server with my database mysql on elsehwhere? Or is it possible to insert data via an air application?

  Here is the example that I follow:-

  Thanks for the replies boys. I decided I'll change in a flex app rather then it would be any problems. It just means I'll have to add a login system.

  While were on the subject you guys happen to know of examples anywhere of how someone can DELETE data in a table sql via flex/php?

  I'm looking for is essentially when a user uses my application and between info in some text entries, if this specfic info exists in a table so that the data will be deleted from the table. The way this works is that they will choose an element in a tilelist populated by the data in this table mysql and this will insert the data from the selected item in the text entries and then they click a Remove button to remove this element. Cannot find anything similar anywhere well.

  You will need to use a common identifier, for example:

  give each line of your database of ID.

  then pass this value to ID the press of button to a PHP script, that something like:

  $deleteID = $_POST["delID"];
  
  mysql_query("DELETE FROM exampleTable WHERE ID='$deleteID
  '");
  

  maybe check if a line with this ID exists primarily for verification, then go back a value that indicates whether the deletion was successful or not.

  You can delete on other values, but remember they must be unique in the database, otherwise you run the risk of clear multiple values.

  Or you could delete on a compound key, based on the data that you store in the grid.

• NPE for rows with null values in the table of the adv

  I created the table adv, 2 columns, equipped with two text fields. Initially the col2 is empty,
  say that the structure is as follows:

                col1          col2
  Hdr         Question    Answer
  row1       abc           zxc
  row2       pdd           null (user doesnt enter anything)
  row3       zxc            lkj
  
  APPLYBUTTON

  When the user clicks on apply button I want to update these values in the table.
  
  I don't know how to do that, but that's what I'm trying to do. Please guide me the right way if its wrong.
  
  in LICS, I took the APPLYBUTTON action, got all lines of the object corresponding to the view, consulted with everyrow and I'm checking if there are values in the fields in the table, if the value zero, are simply print null. (we would not update on this line). . I could get o the part update, due to null pointer exception
  I get on the row line null pointer exception [1].getAttribute("Answer") for row2, it prints the value of row1 however.
  
  Here is the code I wrote:
  Set of rows from the rowset = (RowSet) vo.getRowSet ();
  Rank rank [] = vo.getAllRowsInRange ();
  System.out.println ("row.length" + row.length);
  for (int i = 0; i < row.length; i ++) {}
  String question = row.getAttribute("Question").toString ();
  String response = row [i].getAttribute("Answer").toString ();
  If (question! = null & &!("".)) Equals (question. Trim()))
  {
  System.out.println ("Question line" + i + "-" + question);
  }
  on the other
  {
  System.out.println ("Question line" + i + "is null");
  }
  
  If (response! = null & &!("".)) Equals (Answer.Trim ()))
  {
  System.out.println ("Response line" + i + "-" + response);
  }
  on the other
  {
  System.out.println ("Response line" + i + "is null");
  }
  
  Why the NPE survey code, I'm checking for null value and you want to print the value null in the logfile... I can not to getAttribute() on the null field, why can not just give me null in the variable I'm assigning to?
  
  You can guide me what approach to take, if it is not correct.
  I must examine DataDictionary and collect data there?
  Thanks in advance.

  Hello

  handle the exception of null on these two statements like this pointer

  String question = "";
  String response = "";

  Try
  {
  question = row.getAttribute("Question").toString ();
  }
  catch (NullPointerException e)
  {
  question = "";
  }

  Try
  {
  answer = row.getAttribute("Answer").toString ();
  }
  catch (NullPointerException e)
  {
  response = "";
  }

  Si ( !("". Equals (question. Trim()))
  {
  System.out.println ("Question line" + i + "-" + question);
  }
  on the other
  {
  System.out.println ("Question line" + i + "is null");
  }

  Si ( !("". Equals (Answer.Trim ()))

• How do you find the average value of all the data between two points on a single channel

  I'm tring to calculate the average value of all data points in a single field between two distinct points

  I rasthaus an illustration.

  Hi smoothdurban,

  I thought you wanted to specify the area of interest with the sliders of the band.  If you rather automatically define the area of interest based on thresholds, etc., we cannot see the interactive nature of the example I sent.

  What are the criteria used to determine the start and end of the region of interest lines?

  I would be able to type this out for you if you sent a representative data set ([email protected])

• Find the average value of a buffer

  Hello

  In my VI Panel, I have a digital control, a button and a digital display.

  When the user, enter a number in numerical order and press the button, the digital display should show the average value of all the past 5 values entered in the digital control, for example:

  1st entry: 10-online average = 10 (as sum = 10)

  2nd type: 0-online average = 5 (as sum = 10 + 0 = 10)

  3rd enter: 5-online average = 5 (you get the idea...)

  4 enter: 1-average online = 4

  5 enter: 14-online medium = 6

  6 enter: 2-online average = 4.4 (sum = 0 + 5 + 1 + 14 + 2 = 22, because the 1st value is thrown)

  How to write this VI?

  Thank you!!

  You can also use arrays to hold the data in a registry change and find the average value of the last five items.

  

  Good luck

• maximum values of five table 2d

  Hi, I have a vi that reads in the values of a 2D array, and then uses this information. I currently use the vi 'Table Max and Min' to find the maximum values of the table. It can be beneficial for my application find the maximum of 5 or any other number of values in the table. My current plan is to use a loop that detects that the maximum value of the original array and then subtract this value and repeat the operation once 5 or greater. However, I believe that it is innefficient and can take a long time in a vi that must run pretty quickly. I would like suggestions. Thanks in advance.

  It would be a bit faster

• Find most common value in a table of enums

  Hello

  I'm looking for a stylish way to find most common value in a table of enums

  My being of enum:

  0 - close

  1 - open

  2 - undefined

  For example, if my table contains:

  Close, close, open, close, close, open.

  The most common value would be 'Closed'

  I created a very personalized VI which allows me to get the desired result, but I'm really not proud of doing it this way, just simply because I need to change if I add a new value to my enum...

  If anyone can share some ideas to enlighten me, I would REALLY appreciate it.

  Thanks in advance!

  I don't know, I'd go the yard road, to propose, he could save a single iteration since you know 0 is the first point of departure, but you then must deal with the determination of lengths and dealing with missing values that return-1, etc..

  If you really expect of very large tables, I would have moved my previous version which is supposed to be quick to write in another simple method of counting.
