The interp1 X-Function dialog box is typical of Origin's analysis dialog boxes. Note that at the top of the dialog box, there is a list box used for naming or retrieving a Dialog Theme -- a particular group of dialog box settings. Directly beneath, is a brief Description of what the tool does.
The center portion of the analysis dialog box lists the controls specific to a particular tool (though some of the same controls may appear in other dialog boxes). These controls are organized in a tree-like structure, with branching sections marked and controlled by a familiar or control.
