  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

• 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.

  

• [Labview] I want to get the average value in each new 100 samples.

  Hello. I'm Sophie.

  I'm studying Labview for my research.

  For me, the sampling frequency is 125KHz.

  I want to get the average value in each new 100 samples.

  Therefore, I want to get an average value of 1 ~ 100th samples and store this average value. Call assets(1).

  Then, I want to get an average of 101 ~ 200th samples and store this means value, call moyen2.

• 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).

  VI on the attachment. (simplified version of the complete system)

  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

  I'm using LabView 2009

  Thank you very much.

• 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?

• 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.

• How the two function return values

  Dear all,

  Please explain, how the two values of function return?

  give a simple example.

  OK, a few examples...

  First example, using a type of structured on the database object:

  SQL > create or replace type tMyValues as an object (yr number, number, number of dy mn)
  2.

  Type of creation.

  SQL > create or replace function getMyValues return tMyValues is
  2 number of y: = extraction (year sysdate);
  number of 3 m: = extraction (sysdate months);
  number of 4 d: = extract (day of sysdate);
  5. start
  6 return new tMyValues(y,m,d);
  7 end;
  8.

  The function is created.

  SQL > set serverout on

  SQL > declare
  2 myValues tMyValues;
  3. start
  4 myValues: = getMyValues();
  5 dbms_output.put_line (' year: ' | myValues.yr);
  6 dbms_output.put_line (' month: ' | myValues.mn);
  7 dbms_output.put_line (' date: ' | myValues.dy);

• Insertion of the calculated values and values into a new table. How?

  Hi guys. Had a slight dilemma here. My problem is that:
  
  1. I have an average of two values (in the same column) for the 2 different lines (which is 7 days before the event and the other which is 14 days). I need to insert a new table
  
  WITH
  
  2. the data in some of the other columns of the lines of these two values I have on average.
  
  So, for example, I have the source table table S, with the values of Company_Name, Date, name of the Emp, salary, Date. I have to calculate the average salary, corresponding to the date criteria I described before. So I have to insert into another table (the average value) while keeping other data (Date, name of the Emp) etc.
  
  This is really confusing me. I think that the mix of simple db and sql pl theory is to play with my head.
  
  I know that the scenario is a bit confused, so please ask any questions! I'll check this thread very frequently!

  Frankly speaking, I'm lost.

  Please post some samples of entry and your required output in a formatted way.

  Kind regards.

• Read TDMS - calculate the average

  Hello

  I have data I stored in a PDM file, I want to do some calculations, such as finding the average of all of my data.

  Successfully, I have read the PDM file and linked to a waveform graph, no problem on this part.

  However, I'm stuck trying to figure out how can I access data other than just to print them on a graph.

  How could I summarize all the values to find the average value?

  I am using LabVIEW 2010.

  Thank you.

  Use the Mean.vi function under the probability and statistics.  I'm guessing that you read a wave form and you may need to remove the values of Y by using the function to get the elements of waveform.  Display code if you get stuck.

• 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.
