Overview
To dynamically set a waveform chart's x-axis minimum and maximum value based on the sample rate and the number of samples per channel.

Description:
This example shows how to dynamically set a waveform chart's x-axis minimum and maximum value based on the sample rate and the number of samples per channel.  The x-axis is also set to start at a relative time of zero.  The example is setup to read and display 3 channels.

Steps to implement or execute code
To implement this example:

  1. Define the physical channel to be used
  2. (Optional) Set the rest of the parameters as needed
  3. Run the VI


To execute this example:

  1. Install the required software.
  2. Connect the DAQ hardware that supports the Analog Input features
  3. Confirm the connection with the MAX with TestPanel
  4. Open the VI and refer the Implement Steps


Requirements
Software
LabVIEW 2012 or compatible
NI-DAQmx 16.0 or compatible

Hardware
cDAQ with C series Analog Input Module
