• 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])

• 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.

  Can anyone help?
  
  Thank you

  You must go to the current line, that is included as twelfths a form 11 months.
  If you round the result is 67,42 67,41 rather than. This is the result on all the cust_num.
  If you want to the result for each customer comment just the partiton of clause.

  SELECT      cust_num, month, agreed_rate
  ,      round (sum (agreed_rate) OVER ( --PARTITION BY  cust_num
                                  ORDER BY month
                     RANGE
                     INTERVAL '11' month
                     preceding
                     ) / 12,2) AS avg_agreed_rate
  FROM       test
  ORDER BY  month
  

  Partition on cust_num

  SELECT      cust_num, month, agreed_rate
  ,      round (sum (agreed_rate) OVER ( PARTITION BY  cust_num
                                  ORDER BY month
                     RANGE
                     INTERVAL '11' month
                     preceding
                     ) / 12,2) AS avg_agreed_rate

• Calculate the average per slot?

  Hi Chaps,

  I am a beginner on numbers (almost everything on Mac I would say) and I need help to calculate average values.

  These are calculated values (column 2) taken on a specific time of the day (column 1).
  I managed to create a third using a built-in function to get the time slot (column 3).

  14:58:42	235	14
  14:59:42	274	14
  15:00:50	7937	15
  15:01:55	5157	15
  16:02:57	1822	16
  16:03:57	207	16

  Can please somebody see me step by step how to calculate the average by time slot as below?

  14	254,5
  15	6547
  16	1014,5

  Kind regards

  This can help you

  

  Assuming you data in a table named 'Data' and the information is summarised in another table (right) named "Summary".

  Select cell B1 in the summary table and then type (or copy and paste from here):

  = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  shortcut for this is:

  B1 = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  Select cell B1, copy

  Select column B, paste

• Filtering and calculate the averages for subsets of a table

  I have a 2D picture that comes out of a loop, and I need to calculate the average of the subsets corresponding to iterations 0-9, 10-19, etc...  In addition, I need to filter the values above and below acceptable limits before calculating the average.  Any suggestions for how to address the issue?

  Here are examples of code does exactly that. This post, looks like you need an upper limit as well. I'll leave that as an exercise for you.

• 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?

• HO to calculate the average in the Transient attribute?

  code to calculate the sum is
  
  public getEmpOverallRating() number + {+
  RowIterator comp = getEmpSkillView();
  Number sum = new Number (0);
  + all in (comp.hasNext ()) {+
  sum = sum.add ((Number) comp.next () .getAttribute ("Ratting"));

  Set the default value of the transient attribute to type of expression with a value like SkillView.avg ("Rating") where SkillView is the VO.

• PDF form field calculates the AVERAGE incorrectly

  I have a PDF form field which is defined to calculate the AVERAGE of the other 4 fields. Each of these other areas has its validation configured to allow only the values from 1 to 3.
  
  The average field is dividing the total by 4, even if a person completes only 2 fields. I thought THAT AVERAGE would count only the fields that have a value in them. But it is to see which ones are empty as containing a 0, even if it is an invalid value for this field.
  
  How can I fix? The client really wants to have up to 4 fields and an average of only those that are filled. I thought it was what average was supposed to do.
  
  Is there a way to tell Acrobat to ignore fields if their value is less than 1?

• JavaScript to calculate the average of a column

  I have my PDF file I'm trying to calculate the average in a column of fields.

  My problem is that there are 7 areas, but all 7 can be omitted, so I think I need some sort of statement 'if' that would only count the number of fields containing values.  Then, somehow working in the rest of my calculation...

  That's what I have so far...

  (function () {}

  Get all the field values, as numbers
  var v1 = + getField("column.0").value;
  var v2 = + getField("column.1").value;

  var v3 = + getField("column.2").value;

  var v4 = + getField("column.3").value;

  V5 var = + getField("column.4").value;

  var V6 = + getField("column.5").value;

  v7 var = + getField("column.6").value;

  var V8 = + getField("column.7").value;
  
  Calculate the result and the value of this field
  Event.Value = (v1 + v2 + v3 + v4 + v5 + v6 + v7) / the number of fields that have been filled;

  })();

  I'm pretty new to javascript. Any help would be greatly appreciated! Thank you

  First of all, I woul write this function withou field reference to make it more universal, and then I have a funcion of document level so it could be used more than once in a PDF document and easily put into another PDF file.

  function Avg() {}
  average computer of the last non-empty field names
  var sum = 0; sum of the fields
  var number = 0; meter for non-empty fields
  for (i = 0; i< arguments.length;="" i++)="">
  iField var = arguments [i]; get the element of arguments passed
  var fField = this.getField(arguments[i]).value;
  If (!) isNaN (fField)))) {}
  field is a number
  If (fField.ToString ()! = ") {}
  field is not null or empty
  sum += Number (fField); Add to the sum
  Count ++; County of increment
  } / / do not blank end
  } / / end of number
  } / / end of loop iterative arguments
  If (count! = 0) {}
  calculate the average if there is one or more items on average
  to return the sum / count; Returns the average
  } else {}
  return ";
  } / / no end no average calculated
  } / / end of function Avg

  Your custom calculation script would then become:

  Event.Value = Avg ("column. 0', 'column.1', 'column.2', 'column.3', 'column.4', 'column.5', 'column.6', 'column.7');

• 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.

• 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
