SETZ

Purpose:

Specifies the z-axis coordinate range of a Window.

SETZ(win, zbottom, ztop)

win	-	Optional. Window reference. Defaults to the current Window.
zbottom	-	A real. The bottom 3D axis boundary.
ztop	-	A real. the top 3D axis boundary.

W1: xyz(grand(10,1), grand(10, 1), grand(10, 1))

setz(-3.0, 3.0)

creates a 3D series and sets the Z axis range from –3.0 to 3.0.

setz(min(W1), max(W1))

sets the z-axis range from the minimum value of the series to the maximum value of the series.

W1: spline2(randn(5), 40);setplottype(4);hot;sethatch(0);gridhv

W2: W1;hot;setz(-1, 1);sethatch(0);gridhv

W1 contains a high density 3D surface.

W2 contains the same surface, but sets the Z plot range from -1 to 1. Values outside the Z range are not displayed.

See SETZTIC to set the tic spacing.

See SETZAUTO to specify the Z autoscale range.
