Graph Control (G Dataflow)

Plot numeric, complex, X/Y, or point sample data contained in arrays and analog waveforms.

What Types of Data Can I Plot?

You can plot numeric, complex, or point sample data contained in arrays and analog waveforms. By default, the graph data type is an array of doubles. You can change the data type on the diagram.

The waveform data type carries the start time (t0), delta t (dt), and y-values (Y) of a waveform. When you wire waveform data to a graph, the graph automatically plots a waveform based on the start time, delta t, and y-values of the waveform.

For data contained in arrays, the graph displays a general-purpose Cartesian graph that plots any set of points, evenly sampled or not.

The following table describes how graphs plot different types of array data.

Data Type Plot Behavior
1D array of numeric values

The array is a single plot.

• X-value: Array index
• Y-value: Array element
1D array of complex or cluster values

The array is a single plot. The cluster must be a two-element cluster.

• X-value: First element of the complex number or cluster
• Y-value: Second element of the complex number or cluster
Cluster of two 1D arrays of numeric values

The cluster is a single plot.

• X-value: Elements of the first array
• Y-value: Elements of the second array
1D array of waveforms Each waveform is a separate plot.
2D array of numeric values Each row of the array is a separate plot.
2D array of complex or cluster values Each row of the array is a separate plot. The cluster must be a two-element cluster.
• X-value: First element of the complex number or cluster
• Y-value: Second element of the complex number or cluster
1D array of clusters of 1D arrays Each cluster of arrays is a separate plot. Arrays within a cluster must be the same size, but arrays in different clusters can be different sizes.
Cluster of two numeric values and a 1D array The cluster is a single plot.
• X-value: An initial x value incremented by a delta x. The first numeric value represents the initial x value, and the second numeric value represents the delta x value
• Y-value: Elements of the array
