Specifying Transparency
Transparency values, which range from [0 1], are referred to as alpha values. An alpha value of 0 means completely transparent (i.e., invisible); an alpha value of 1 means completely opaque (i.e., no transparency).
MATLAB treats transparency in a way that is analogous to how it treats color for the respective objects:
See the following sections for more information on color:
Transparency Properties
The following table summarizes the object properties that control transparency.
Property |
Purpose |
AlphaData |
Transparency data for image and surface objects |
AlphaDataMapping |
Transparency data mapping method |
FaceAlpha |
Transparency of the faces (patch and surface only) |
EdgeAlpha |
Transparency of the edges (patch and surface only) |
FaceVertexAlphaData |
Patch only alpha data property |
ALim |

Transparency Functions
There are three functions that simplify the process of setting alpha properties.
