LabVIEW
Programming labview
Hi again,
right, i've been trying to change something myself, but it seems i'm
useless in this. well, at least i know what's "vi" now and can find a
diagram, but that's it:)
find attached to this message the vi i want to change and the example of
results i get. i will also attach a doc file with a pic explaining what i
want to change.
apparently, the vi i use is just one of the examples in LabView (High Speed
Data Logger and High Speed Data Reader). so, i run the data logger during
my cutting test for about 200000 readings, then i stop it, save the file
and view it in the data reader. all i get is a diargamm showing the graphs
of forces in 3 directions. after i have to view each cycle on the diagramm
to find the average max value of each force (i take 10 readings for each
force in every file and the calculate average). this is very time
consuming.
basicly i don't need the diagramm, all i need is the
average max value for each of 3 forces within one file. this would really
help me and save my time.
i hope my explanation is ok, because my english is not so good, so if there
are any questions - please ask. i hope you can help me because it seems
that i can't do it myself or it'll take me really long time, though i'm
sure that it's possible to make these changes.
Many thanks!

Hello Evgenia,
maybe this could help you. I changed the Reader.vi to show the mean of a plot...
(I could not test it because of missing data and missing subVi.)

i'll as soon as i get the equipment set up, to check if it works.
Hi there again,
well, i've just checked the new reader, and it's not what i need it shows the mean of everything together, but there are 3 curves and i need a mean for each of them...please, if somebody can do this, this would be great, i really need it!
i've just tried to attach an example of the readings i get to this mesaage, maybe this could help, but the file has no valid extension, it's just a "file", so i can't attach it:(
well, anyway, if anybody can help me, this would be just great
many thanks
Hello Evgenia,
just rename your file before attaching... (Extension txt will do in most cases.)
To your data reader:
the data is shown in indicator "LOGGED DATA". From that indicator/wire i take one row of data (you may change this to columns) and get the mean of it. What else do you want when you say: "there are 3 curves and i need a mean for each of them"? At the moment you can select the curve to compute the mean from with 'index (row)' control.
But well, I changed it to compute the mean of all curves of your plot.
