Waveform Chart Displays Incorrect Number of Plots in LabVIEW

Issue Details

I have created a simple VI to visualize 20 plots with 20 data points for each of them. However, I can only see 9 plots on my waveform chart. Kindly refer to my VI snippet below for better understanding on my concern.

Note: This image is a LabVIEW snippet, which includes LabVIEW code that you can reuse in your project. To use a snippet, right-click the image, save it to your computer, and drag the file onto your LabVIEW diagram.


The default amount of array that will be converted into the cluster is nine. Therefore, to convert more than nine arrays into clusters, you have to double-click Array to Cluster node and input the correct amount of array you wish to convert into clusters.

Additional Information

The maximum size array that can be converted into a cluster using the Array to Cluster functionis 256 elements. 
Using a Type Cast function can be more complex, but can be used to convert arrays larger than 256 elements into clusters.
