Width of Hysteresis

[gregorian7]

Hi GerdW,

Thanks for your reply.

1. Separate your data into the up and the down cycle.

At the moment all plot date are stored in one array. How can I split in for up and down cycle date? Find the index with max value  for Y and create subarrays?

Hi Gregorian,

How can I split in for up and down cycle date? Find the index with max value  for Y and create subarrays?

I took your data "3.csv" and played with it using Excel:

1. Take the first half of the measurement data, containing just one "pulse"
2. Delete all datapoints with Y < 0.1
3. Search the max value for Y in the remaining data
4. split the remaining data at max(Y): the first part of the data contains only rising Y values, the 2nd part only decreasing Y values
5. Now you have 2 curves: one for the upcycle of the hysteresis measurement, one for the downcycle.
6. Use Threshold1DArray to search/interpolate interesting data like finding X values for certain Y values…

See how far you get and attach your VI with some example measurement data again.

Btw. IMHO a VI should not have a filesize of 9MB (or more). Especially when the filesize is dictated by that huge image you placed in the frontpanel! To lower the filesize you could scale that image to a reasonable size!

Hi GerdW,

Thank you for your message.

Can you have a quick look on my VI if does it make any sense to you. I don't know why all data in "Index2" array is 0. 

Thanks,
