Tools Workflow

Zooming in Graphs

Zooming changes the magnification of a graph without changing the size of the figure or axes.

Panning — Shifting Your View of the Graph

You can move your view of a graph up and down as well as left and right with the pan tool.

Rotate in 3-D

You can rotate graphs to any orientation by enabling rotation mode and controlling rotation options,

View Control with the Camera Toolbar

The Camera toolbar enables you to perform a number of viewing operations interactively.

Programmatic Workflow

Camera Graphics Terminology

Graphics provides functionality, analogous to that of a camera with a zoom lens, that enables you to control the view of the scene.

Understanding View Projections

Graphics supports both orthographic and perspective projection types for displaying 3-D graphics. The one you select depends on the type of graphics you are displaying.

Low-Level Camera Properties

Camera graphics is based on a group of axes properties that control the position and orientation of the camera.

Setting the Viewpoint with Azimuth and Elevation

You can control the orientation of axes using graphics functions.

Dollying the Camera

The camdolly function allows you to move both the position of the camera and the position of the camera target in unison.

Moving the Camera Through a Scene

This example shows how to move a camera along a path traced by a stream line and how to move a light source with the camera.

Manipulating Axes Aspect Ratio

There are several axes properties that control the aspect ratio. Set these properties to achieve the effect you want.
