more information about Clusters refer to Chapter 14, Array and Cluster 
Controls and Indicators, in the G Programming Reference Manual.

Graphs

A graph is a two-dimensional display of one or more data arrays called 
plots. There are three types of graphs in the Controls»Graph palette:

• XY graph

• Waveform graph

• Intensity graph

This palette also contains the Historical Trend, which is an XY Graph 
specifically configured for displaying logged data in BridgeVIEW. The 
difference between a graph and a chart (discussed in Chapter 10, 

, in this manual) is that a graph plots data as a block, whereas a chart 

plots data point by point, or array by array.

For examples of graph VIs, see

Customizing Graphs

Both waveform and XY graphs have a number of optional parts that you 
can show or hide using the Show submenu of the pop-up menu for the 
graph. The options include a legend, through which you can define the 
color and style for a given plot, a palette from which you can change scaling 
and format options while the VI is running, and a cursor display. The 
following illustration of a graph shows all of the optional components 
except for the cursor display.
