Clusters group data elements of mixed types. A cluster is similar to a record or a struct in text-based programming languages.
You can choose from the following cluster types, and clusters can be nested:
|Groups a checkbox, numeric control, and string control together to input error information.||Error In|
|Groups a checkbox, numeric indicator, and string control together to display error information.||Error Out|
|Groups a timestamp, numeric array, and numeric control together to display waveform data.||Waveform|
|Create a custom group by dragging and dropping controls, such as buttons, graphs, arrays, and so on, into the cluster shell.||Empty Cluster|
You can reorder cluster elements by using the Data Items section on the Item tab or by moving controls inside or outside the cluster. The order of the controls within the cluster is determined by the order in which you add them to the cluster.
Press Ctrl-Down Arrow or Ctrl-Up Arrow to tab through cluster elements, even nested clusters.
