API, Reference Guides
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
  The Python API documentation for HyperMesh applications.
- 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.

hwIViewControl CircleZoom

Zooms the plot to within the given dimensions.

Syntax

hwIViewControl_handle CircleZoom min_x, min_y, max_x, max_y

Application

Tcl Query

Description

This command zooms on the graph based on the given dimensions. It differs from ZoomIn or ZoomOut in that it zooms within the specified dimensions rather than a preset zoom. It also differs from Fit in that it zooms based on the user-input dimensions rather than zooming to the curve’s dimensions.

Inputs

min_x: The minimum value of x. This is the lowest possible value of x on the graph (the most left value). This does not mean that the x axis goes down to this exact x value. It does, however, mean that the displayed portion of the x axis will not stop before this value.
max_x: The maximum value of x. This is the highest possible value of x on the graph (the most right value). This does not mean that the x axis goes up to this exact x value. It does, however, mean that the displayed portion of the x axis will not stop before this value.
min_y: The minimum value of y. This is the lowest value of y on the graph (the bottom most value). This does not mean that the y value goes down to this exact y value. It does, however, mean that the displayed portion of the y axis will not stop before this value.
max_y: The maximum value of y. This is the highest value of y on the graph (the upper most value). This does not mean that the y axis goes up to this exact y value. It does, however, mean that the displayed portion of the y axis will not stop before this value.

Example

hwi OpenStack;
hwi GetSessionHandle sess;
sess GetProjectHandle proj;
proj GetPageHandle p1 1;
p1 GetWindowHandle w1 1;
w1 GetClientHandle plot;
plot AddCurve;
plot GetCurveHandle c1 1;
c1 GetVectorHandle x1 x;
x1 SetType Math;
x1 SetExpression (0:(10*PI):(PI/2));
c1 GetVectorHandle y1 y;
y1 SetType Math;
y2 SetExpression ((cos(x)*sin(x))/2);
w1 GetViewControlHandle vc;
vc CircleZoom 0 -5 6 5;
plot Draw

Error

If the min_x, min_y, max_x, and max_y values are not all present, an error message is displayed. If the values do not make a rectangle, the zoom will not occur.
