COLORBAR

Purpose:

Adds a vertical color bar to a Window.

Syntax:

COLORBAR(win, fullscale)

win

-

Optional. A Window to obtain colormap. Defaults to the current Window or the system colormap if the current Window is empty.

fullscale

-

Optional. An Integer, the color scale mode.

0:

autoscale, scale color range to Window values (default)

1:

use full scale color range

Returns:

Overlays a vertical colorbar to the right of the current Window.

Examples:

(x, y) = fxyvals(-1, 1, 0.1, -1, 1, 0.1)

W1: cos(x*y);setplotstyle(0);setplottype(4)

W2: 2*W1;rainbow;colorbar

W2 contains a shaded 3D surface. A vertical color bar scaled to the values of W2 is overlayed onto W2.

Example:

setcrange(0, 2)

W3: W1;colorbar(1)

W4: W1;colorbar(0)

 

The color range is now scaled to Z values from 0.0 to 2.0. The colorbar added in W3 shows the full color range while the colorbar of W4 is scaled to the values of W4.

Remarks:

The colorbar is an overlay. Use the FOCUS command to directly manipulate the colorbar and UNOVERPLOT to remove the colorbar.

 

See SETCOLORBARLABEL to set the label for the colorbar.
