Two methods for writing multiple plots to a waveform chart

[mr-vizsla]

Overview

This example shows two methods for writing multiple plots to a waveform chart.

Description

The first method uses a bundle function to combine the single data points into a cluster.

The second method converts each single data point to a 1D array using a build array function and then combines the 1D arrays into a 2D array using another build array function. In order to display the 2D array correctly, the Transpose Array option of the chart is disabled. If you need to do this in your code, right-click on the chart border and deselect Transpose Array as shown in the image below. This option is only enabled for Array data types.

Requirements

LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

Run the attached VI

Feel free to download the VI and right-click, show as icon. Hope that helps.

If I want to change the X-axis to show the real time, how can I do that? I understand I have to use "Build Waveform" and intrudoce the real time to the chart but then I can only wire one array to Y ... how can I include al the plots and get the chart to show real-time?

When I try doing this myself, "transpose array" is grayed out when Iright click on the chart.  I'm not the only person whose had this problem.  Any ideas?
