SETZAUTO

Purpose:

Specifies the z-axis Window coordinates for autoscaling.

Syntax:

SETZAUTO(win, zbottom, ztop)

win

-

Optional. Window reference. Defaults to the current Window.

zbottom

-

A real. Bottom Z boundary.

ztop

-

A real. Top Z boundary.

Example:

W1: spline2(randn(5), 10);setplottype(4);hot

W2: w1;hot;setzauto(-1, 1)

 

W1 contains a spline interpolated random array displayed as a Z surface.

W2 contains the same surface but sets the Z autoscale range from -1 to 1. The image is clipped to the Z auto range when autoscaled.

Remarks:

A Window can be autoscaled with the AUTOSCALE function, by pressing Ctrl-Home when the Window is activated, by pressing the Autoscale button or selecting Autoscale from the right click popup menu.

 

Use setzauto(-1, -1) to set automatic z-axis autoscaling. CLEAR also resets autoscaling to automatic.
