mean values to array

[bugmaker]

Hi

As new in LabView I am having difficulties in saving my measurement data. I have some images from which I measure their color mean values. After measurement I want to save  these measurements in an excel sheet, but I somehow fail to save these into a some kind of array and consequently I get only the last color value of the last image. Any ideas how to preserve all values?

Use a loop to read the values(A while loop or a for loop).Right click the array structure and choose enable indexing.Now you will get all the values.Use write to spread sheet function to write the values and save it.

I am trying but I still don't get the wanted results. I have exaclty 20 images. attaching the part of the code.

You have to put your value generator inside the loop.

Hi

while it works generally it still doesn't work for my specific example.

See in the diagram instead of random numbers u can put your "Image to mean value generator".

It doesn't work. With this method I get the last value written 20 times at the excel sheet. I have looked pretty much how to do this, and frankly I am frustrated not to be able to do it.

u have to have the read value  function,Inside the for loop.For each iteration u will be reading a different value and at the end of it if you index it u will get all the values.In your vi u are just converting the last value into double.So obvoiuosly the number of iterations specified by u will the the last value ouput so many times.
