Specifying Patch Coloring

Patch coloring is defined differently from surface object coloring 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.

You can specify patch face coloring by defining

• A single color for all faces
• One color for each face, which is used for flat coloring
• One color for each vertex, which is used for interpolated coloring

Specify the face color using either the CData property, if you are using x-, y-, and z-coordinates, or the FaceVertexCData property, if you are specifying vertices and faces.

Patch Color Properties

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

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
