How to sample only on a measurement change
If only the data points that show changes in values are desired, it is possible to filter out data points that are duplicates of the previous values.
The sample calculations can be placed into any Capstone workbook where the data points that do not have measurement changes above a critical value will not be shown.
Use of the Change Filter.
changefilteredposition=chgfilter(0.0000001,[Position (m), ?])
Returns a copy of the data source X that includes the first value and only those values with a change in value greater than "Change" compared to the prior value. All other values are removed.
change = value only
x = data only
