 Arrays
 Clusters
 Error Cluster
 Enumerations
 Graphs and Charts

3. Review Question 1
True or False?
1. Arrays can contain only one data type.
2. An array must contain at least one element.
3. The Bundle function can be used to add elements to a
cluster.
4. Clusters can contain both controls and indicators within the
same shell; however, arrays cannot.
5. It is possible to have clusters containing arrays as well as
arrays containing clusters.

4. Review Question 1
True or False?
1. Arrays can contain only one data type. TRUE
2. An array must contain at least one element. FALSE
3. The Bundle function can be used to add elements to a
cluster. FALSE
4. Clusters can contain both controls and indicators within the
same shell; however, arrays cannot. FALSE
5. It is possible to have clusters containing arrays as well as
arrays containing clusters. TRUE

5. Review Question 2
The Error Cluster contains which of the following?
a) Boolean
b) Array
c) String
d) Numeric
e) Cluster

6. Review Question 2
The Error Cluster contains which of the following?
a) Boolean - status
b) Array
c) String - source
d) Numeric - code
e) Cluster

7. • Cluster elements have a logical
order unrelated to their position in
the shell
• You can view and modify the
cluster order by right-clicking
the cluster border and
selecting Reorder Controls
In Cluster from
the shortcut menu
• Order determines how cluster is
unbundled
Clusters: Order

8. • Clusters differ from arrays in that they are a fixed size
• Clusters can contain mixed data types; arrays contain only
one data type
• Like an array, a cluster is either a control or an indicator
and cannot contain a mixture of controls and indicators
• You can create a cluster of clusters, cluster of arrays,
array of clusters, but NOT an array of arrays
Clusters vs. Arrays

9. Enumeration
• An enum represents a pair of values, a string and
a numeric, where the enum’s value is one of a
defined list of value pairs
• Appears as a string to you, and a number to computer

10. Enumeration: Configuring
1. Right-click on the enum
2. Select Edit Items…

Configuring an Enum

12. • Chart:
• Remembers history – new point added to end of plot
• Good for inside a loop
Graphs vs. Charts
• Graph:
• New plot of all new data
• Good for outside the loop
• Use the Context Help window
to determine how to wire multi-
plot data to Waveform Graphs
and XY Graphs

13. • Right-click the chart and select Advanced»Update
Mode from the shortcut menu
• Strip chart is the default update mode
• Scope chart and Sweep chart modes display plots
significantly faster than the strip chart mode
Chart Update Modes

14. Demonstration 2:
Plotting Charts and Graphs
