Use Cursor on Waveform Graph to Increase Graph Area During Runtime

[Claire_Reid]

Overview

Coding that exemplifies how to increment the graph area by moving the cursors.

Description

This example allows you to drag the cursor in the graph with the mouse to expand the X and Y scale of the graph. The position of the cursor is read via property nodes which contains the cursor position and allows the VI to read both the X position and the Y position of the cursor. The X and Y scale are then modified by using the range properties to set the maximum value for the X and Y scale. These properties are continuously monitored inside a while loop. The case structures monitor the properties within the while loop and restore the graph to its original size as needed.

Requirements

LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code
1. Configure the following front panel controls:
          * frequency
          * amplitude
          * offset
          * phase
          * sampling info
2. Run the VI
3. When you drag the yellow cursor around, the graph will resize as needed
