Overview
This VI shows how to convert unevenly-spaced digital data into a form that you can plot on a waveform graph in LabVIEW.


Description
In order to be plotted on a waveform graph, the data must be evenly spaced. You could use this technique to display time-variant (unevenly spaced) digital data on the same graph that you use to display corresponding analog data.


Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Set unevenly-spaced X values in the "X" array
  2. Run the VI
  3. Note that the Waveform Graph shows the correct values at the correct time points, but has interpolated to provide evenly spaced data.
