Specifying Patch Coloring

Patch objects employ a coloring scheme that is basically different from that used by surface objects in that patches do not automatically generate color data based on the value of the z-coordinate at each vertex. You must explicitly specify patch coloring, or MATLAB uses the default white face color and black edge color.

Patch coloring methods provide a means to display pictures of real-world objects with information superimposed on them through the use of color. For example a picture of an airplane wing can be colored to indicate the air pressure across its surface.

This table summarizes the patch properties that control color (exclusive of those used when light sources are present). See patch properties for a complete list of properties.

Property
 Purpose
CData
Specify single, per face, or per vertex colors in conjunction with x, y, and z data.
CDataMapping
Specifies whether color data is scaled or used directly as indices into the figure colormap.
FaceVertexCData
Specify single, per face, or per vertex colors in conjunction with faces and vertices data.
EdgeColor
 Specifies whether edges are invisible, a single color, a flat color determined by vertex colors, or interpolated colors determined by vertex colors.
FaceColor
 Specifies whether faces are invisible, a single color, a flat color determined by vertex colors, or interpolated colors determined by vertex colors.
MarkerEdgeColor
 Specifies the color of the marker, or the edge color for filled markers.
MarkerFaceColor
 Specifies the fill color for markers that are closed shapes.
