Search Waveform
Returns the timestamp values of the waveform that correspond to a y-axis input value.
Inputs/Outputs
tolerance
The amount, in percentage, values may differ from the input value and still produce a match.
Default value: 0.01
waveform
The waveform you want to search for a particular data value.
Default value: empty
value
The data value for which you want to search.
Default value: 0
start index
Point in the waveform data where the search begins. The node returns an error if start index is out of range for the waveform.
Default value: 0—Corresponds to the beginning of the waveform.
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
| error in does not contain an error | error in contains an error |
|---|---|
|
|
| If no error occurred before the node runs, the node begins execution normally.
If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out. |
If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out. |
indices of fits
An array of indexes of all values that meet the input value and tolerance criteria.
index of best fit
The index of the data value that best matches the input value.
time of best fit
The timestamp value where the data value that best matches the input value was found.
error out
Error information.
The node produces this output according to standard error behavior.
