IGETDATA

Syntax

IGETDATA, ID, Arg1, Arg2, ... [, OBJECT=Value] [, TOOL=iToolID]

Arguments

ID

A string containing the identifier of the iTools object from which to retrieve data. If you pass a partial identifier, the IGETID function is called to retrieve the full identifier string.

Args

Named variables that will contain the returned data.

Keywords

All other keywords are passed to the iTools object.

OBJECT

Set this keyword to a named variable that will contain an object reference to the iTool visualization object specified by Id.

TOOL

Set this keyword to a string specifying one or more iTools in which to search for Id. If this keyword is not set, only the current iTool is searched.

Contour	Z, X, Y	Returns the Z, X, and Y arrays of data.
Image	DATA	Returns the image data.
Plot	[X], Y [, Z]	Returns Y (if one argument is supplied); X, Y (if two arguments are supplied); X, Y, Z (if three arguments are supplied and it is a 3D plot).
Plot3D	X [, Y] [, Z]	If Y and Z are not supplied, a 3xm array is returned in X.
Polygon	VERTICES	Returns a 3xm array of vertices in device coordinates.
Polyline	VERTICES	Returns a 3xm array of vertices in device coordinates.
Region of Interest (ROI)	VERTICES	Returns a 3xm array of vertices in device coordinates.
