Creating Curves from Files or Math Expressions |
|
|
|
|
The Edit Curves panel allows you to create new curves or edit existing ones. Each vector of a curve can be defined using either a data vector in a data file or a math expression. For example, the data source for the x vector could be a file, and the data source for the y vector could be a math expression. The data sources for the x and y vectors are displayed in the x = and y = fields.
To edit the x and y vectors of a math curve, you must indicate the curve number and the x or y vector, in the format curve number.vector: For example:
c1.x To reference the x vector of curve 1.
c1.y To reference the y vector of curve 1.
When you modify a curve, the curves are recalculated in the proper order, based on what has been modified. The y vector can be a function of x or the x vector can be a function of y.
New data can be selected from a source file or mathematically defined. Source file data is divided into type, request, and component.
Type |
Data files can consist of different types of data. Available data types depend on the data file. |
Request |
Once the data type has been selected, the data request set needs to be selected. |
Component |
After the data request set has been selected, the component must be selected. |
