XY Plotting

The functions in the XY Plots module allow you to study the relationships between data vectors in results files. This section introduces the functions that are available.

Information about xy plots is stored in plot collectors, which are referred to as plots. Plots maintain a list of pointers to curves that are to be displayed on the plot. The plot may contain any number of curves. There is no limit to the number of plot collectors that an HM database may contain.

Information about curves is stored in curve collectors, which are referred to as curves. To display a curve, you must assign the curve collector to a plot. A curve may appear on more than one plot at a time and there is no limit to the number of curves that an HM database may contain.

You can create standard plots or dual plots that show real /imaginary or phase/magnitude data.

Procedures for creating and editing xy plots and curves include:

•	Creating an XY Plot

•	Modifying XY Plots

•	Working with Multiple XY Plots

•	Modifying Multiple XY Plots

•	Creating Curves on XY Plots

•	Reading Curves from an ASCII File

•	Creating Analysis Based Curves

•	Creating Curves using Simple Math Operators

•	Creating Curves from Files or Math Expressions

•	Modifying Curve Attributes

•	Displaying Selected Curves on Plots

•	In addition, you can use the Curve Editor to view and modify curves already defined in your HyperMesh model.
