colorbar

Syntax

h = colorbar()

h = colorbar(hAxes)

h = colorbar('on')

h = colorbar('off')

h = colorbar(hAxes, 'on')

h = colorbar(hAxes, 'off')

h = colorbar([c_lo c_hi])

h = colorbar(hAxes, [c_lo c_hi])

[c_lo c_hi] = colorbar()

[c_lo c_hi] = colorbar(hAxes)

Inputs

hAxes

Handle of the axes.

Type: double | integer

Dimension: scalar

on/off

Determines if the colorbar is visible or not.

Type: string

Dimension: scalar

c_lo, c_hi

Lowest and highest ranges.

Type: double | integer

Dimension: scalar

Outputs

h

Handle of the colorbar object.

c_lo, c_hi

Current range of the colorbar.

Example

Simple colorbar example:

cla;
x=[0:0.1:2*pi];
y=x;
z=sin(x')*cos(y);
contour3(z);
colorbar();

Figure 1.

Set colorbar min/max values:

cla;
x=[0:0.1:2*pi];
y=x;
z=sin(x')*cos(y);
contour3(z);
colorbar([-0.5 0.5]);

Figure 2.

Comments

colorbar is available in the contour and contour3 plots.

c_lo, c_hi specify the values assigned to the first and last color in the colormap. Data values lower or higher than c_lo/c_hi will be assigned the lowest/highest color of the colormap, respectively.
