Displaying Waveform Data in a Graph

Last Modified: August 31, 2020

Use a waveform graph control to display data from one or more waveforms in the system definition file to monitor and verify acquired data.

Before you begin, set up timing and logging properties for waveform acquisitions. You can only graph waveforms with a double-precision floating-point data type.
  1. Open the Workspace.
  2. Select Screen»Edit Mode to display the Workspace Controls palette and alignment grid.
  3. Click the Workspace Controls palette.
  4. Select Graph»Waveformand drag the waveform graph onto the alignment grid.
  5. In the Waveform Graph Settings dialog box, select the waveforms to display in the graph and the conditions that you want to stream data.
To configure the x-axis to represent absolute time, right-click a waveform graph and uncheck Ignore Time Stamps.

Note  

By default, the waveform graph ignores the absolute time associated with samples in a waveform and plots relative time on the x-axis. This behavior is useful if the data has no time correlation, or if you want to graph multiple waveforms from two or more systems that are not time synchronized.
