XY Graphs

The XY graph is a general-purpose, Cartesian graphing object that plots multivalued functions, such as circular shapes or waveforms with a varying time base. The XY graph displays any set of points, evenly sampled or not.

You also can display Nyquist planes, Nichols planes, S planes, and Z planes on the XY graph. Lines and labels on these planes are the same color as the Cartesian lines, and you cannot modify the plane label font.

The following front panel shows an example of an XY graph.

The XY graph can display plots containing any number of points. The XY graph also accepts several data types, which minimizes the extent to which you must manipulate data before you display it.

Displaying a Single Plot on XY Graphs

The XY graph accepts three data types for single-plot XY graphs. The XY graph accepts a cluster that contains an x array and a y array.

The XY graph also accepts an array of points, where a point is a cluster that contains an x value and a y value. The XY graph also accepts an array of complex data, in which the real part is plotted on the x-axis and the imaginary part is plotted on the y-axis.

Displaying Multiple Plots on XY Graphs

The XY graph accepts three data types for displaying multiple plots. The XY graph accepts an array of plots, where a plot is a cluster that contains an x array and a y array.

The XY graph also accepts an array of clusters of plots, where a plot is an array of points. A point is a cluster that contains an x value and a y value. The XY graph also accepts an array of clusters of plots, where a plot is an array of complex data, in which the real part is plotted on the x-axis and the imaginary part is plotted on the y-axis.
