How can I have a Waveform Chart using a Waveform Graph?

[matteobr]

Overview

This example demonstrates how to use a Waveform Graph as a Waveform Chart.

Description

This VI shows how to implement a graph with chart behavior.  A graph plots all the available datapoints at once so in order to update it at each iteration like a chart the VI updates the data. In this case a random value is used as data. At the first iteration it initializes all the datapoints on the graph to zero then each iteration the new data is inserted at the end of the array and the waveform is rebuilt.  The x-axis scrolls with the data as it updated.

Requirements

 Software

• LabVIEW Base Development System 2012 (or compatible)
• If running in a Real-Time context, you will need the LabVIEW Real-Time Module 2012 (or compatible)

 Hardware

• No hardware is necessary to use this example VI

The dt input in this sample is incorrect.

The correct units are seconds, so the milisecond input "Time Interval Between Points" should be divided by 1000 first before being input into the Waveform "dt" input.
