HG-1030: Reference and Filter Curves

In this tutorial, you will learn how to reference and filter curves.

The Define Curves panel can be accessed in one of the following ways:

Click on the Define Curves icon,
From the menu bar select Curves > Define Curves

This panel allows you to edit existing curves and create new ones. The Define Curves panel also provides access to the program's curve calculator.

Referencing Curve Vectors in HyperGraph:

x and y vector expressions can reference any curve vector in the session. A curve vector reference defines the x or y vector (values) by page, window, and curve number. An example of a curve vector reference is p2w3c4.x, where:

p2	is page 2
w3	is window 3
c4	is curve 4
x	is the vector

There are two common methods to specify curve vector references:

Pick a curve in a plot window	For the x = input field.	Shift and pick the curve to get the curve x vector reference.
		Shift + Ctrl and pick the curve to get the curve y vector reference.
	for y = input field.	Shift and pick the curve to get the curve y vector reference.
		Shift + Ctrl and pick the curve to get the curve x vector reference.
Select a curve vector reference from the Curves… dialog, which is accessed from the Define Curves panel.
