Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
- Python API

- Tcl/Tk Commands
  The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
  - Program with APIs for Beginners
    APIs can be used to perform various actions in an application. For example, the AddPage API can be used to add a page within the project.

plt3DIWaterfall GetNumberOfSlices

Gets the current number of slices in the waterfall.

Syntax

plt3DIWaterfall_handle GetNumberOfSlices

Application

Tcl Query

Description

A waterfall can contain any number of curves. Unlike in the case of a curve group, the slices are assumed to be related curves and to share an orientation or direction.Returns the number of curves (an integer).

Example

To get the number of slices in an existing waterfall:

hwi GetSessionHandle mySessionName
mySessionName GetProjectHandle myProjectName
myProjectName GetPageHandle myPageName 1
myPageName GetWindowHandle myWinName 1
myWinName GetClientHandle myClientName
myClientName GetWaterfallHandle myWaterfallName 1
myWaterfallName GetNumberOfSlices

Errors

Returns an empty string if the value is not defined.
