Can we construct a waveform using XY pairs in LabVIEW and if yes, then How

[Khalil]

Sir/Ma'am,
I have a query about the waveform data type in LabVIEW.
As we can extract XY pairs [Data Values + Time Stamps] from a waveform,
so can we construct a waveform using XY pairs and if yes, then How? I
will
be
waiting for your response.

Khalil,
If you already have X and Y array of data, it would be easier to use the XY graph. But, you can certainly manipulate the data to get the required inputs for the Waveform Graph.
To create a Waveform Graph, you would use the Build Waveform function. You need to wire Y array, t0 and dt inputs. These second 2 inputs you can get from your X array of data, with some array tools.
Please find the attached example, built with LabVIEW 6.0.2, then builds a waveform graph based on the input X and Y arrays.

Hi, the waveform data type only contains the start and increment of the
timestamp. These values can be extracted and used in a loop to contruct
an array of Time values.
