  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?

• 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.

• 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.

• 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:

• 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.

  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;

  Hello

  If you want to calculate the average of the last 7 days, including the current day, then then RANGE should be 6 PRIOR, not 7.

  Try this:

  WITH got_min_date_val AS

  (

  SELECT id_key, date_val, value_num

  MIN (date_val) compared to (AS min_date_val)

  T

  WHERE the date_val BETWEEN TO_DATE (April 1, 2013 ', "dd-mm-yyyy")

  AND TO_DATE (April 20, 2013 ', "dd-mm-yyyy")

  )

  SELECT id_key, date_val, value_num

  CASE

  WHEN date_val > = min_date_val + 6

  THEN SUM (value_num) OVER (PARTITION BY id_key

  ORDER BY date_val

  PRIOR TO TIER 6

  )

  / 7

  END AS avg_7_day

  CASE

  WHEN date_val > = min_date_val + 6

  THEN AVG (value_num) OVER (PARTITION BY id_key

  ORDER BY date_val

  PRIOR TO TIER 6

  )

  END AS avg_7_day_2

  OF got_min_date_val

  ORDER BY id_key

  date_val

  ;

  Output:

  ID_KEY DATE_VAL VALUE_NUM AVG_7_DAY AVG_7_DAY_2

• How tke an average value to th 0pour 15, 16 and 30, 31-45, 46 and 59 minutes

  

  Here is the picture wt I want to do and also attached with file...

  It is pretty clear to me what you want to achieve but here my 2 cents...

  You have a 2D array and you want it on average by the columns of index 0-15, 16-30, 31-45 46-59.

  Now what I would do is first, split the table 2D-lines in order to have a 4 2D paintings. Then, wrap around the columns and use the "MEAN.vi" LabVIEW for samples on average. Then merge the results.

• Ranking of average values of a table MySQL in PHP (Dreamweaver code)

  Hi all

  I have a table with different entries in this document, including a bunch of columns in which people note criteria, on a basis of 1 to 10.

  As a brief example, I could be a part of the table that looks like this:

  Implementation	Setting_Rating	Product_Quality	Customer_Service_Rating	Speed_Rating
  Dining Room 1	5	8	9	7
  Joes coffee	8	5	6	8
  Moe's Tavern	3	6	7	5
  Big Ben	3	5	4	8
  Mamas House	9	8	10	3
  Fast foodies	7	4	2	9

  What I want to do is to put some tests on my site. The three main functions, I would like to present are:

  "The region is the highest average rating"Customer_Service_Rating"". "

  "At least the top sides (scores from) institutions are:"

  «1: mamas house' "»

  "" 2: big Bens".

  ' 3: dining room 1.

  "The average rating of the Foodies fast is"5"" "

  ... etc, etc, etc.

  Taking these examples as my starting point - how in the world I get this?

  It is difficult to make statistical analyses on several columns. You would do this by using a combination of SQL and programming of the procedure.

  But you can try to create a VIEW that would consist of a UNION that would turn your columns in lines. Something like:

  SELECT the implementation, Setting_Rating, "Setting rating" from myTable

  UNION

  SELECT the implementation, Product_Quality, 'Product quality' from myTable

  UNION

  SELECT the implementation, Customer_Service_Rating, "Note Customer Service" from myTable

  UNION

  SELECT creation, Speed_Rating, 'Speed of note' from MyTable.

  Then you can do your analysis on the VIEW by using the standard SQL aggregates operators (MAX, AVG, etc.) and the Group By clause.

  > and that the table in question has already had a lot of data

  It would be a simple matter to transfer its current form data in the format that I have proposed. However, he would have to rework the front end, so it will take some time for you. Try to create the VIEW I suggested.
