# colorbar

## Purpose

Display color bar (color scale).

## Synopsis

    colorbar('vert')
    colorbar('horiz')
    colorbar(h)
    colorbar
    h = colorbar(...)

## Description

`colorbar('vert')` appends a vertical color bar to the current axes, resizing the axes to make room for the color bar. `colorbar` works with both two-dimensional and three-dimensional plots.

`colorbar('horiz')` appends a horizontal color bar to the current axes.

`colorbar(h)` places the color bar in the axes `h`. The color bar is horizontal if the width of the axes is greater than its height.

`colorbar` with no arguments adds a new vertical color bar or updates an existing one.

`h = colorbar(...)` returns a handle to the color bar axes.
