Patch PropertiesThe second diagram illustrates the use of true color. True color requiresm-by-n-by-3 arrays to define red, green, and blue components for each color.Single ColorOne ColorPer FaceOne ColorPer VertexCDataBGRRGBCDataRedBlueGreen[X,Y,Z]Data[X,Y,Z]DataCDataFace1Face2Face3Face4Face5[X,Y,Z]DataNote that if CData contains NaNs, MATLAB does not color the faces.See also the Faces, Vertices, and FaceVertexCData properties for analternative method of patch definition.CDataMapping{scaled} | directDirect or scaled color mapping. This property determines how MATLABinterprets indexed color data used to color the patch. (If you use true colorspecification for CData or FaceVertexCData, this property has no effect.)• scaled – transform the color data to span the portion of the colormapindicated by the axes CLim property, linearly mapping data values to colors.See the caxis command for more information on this mapping.• direct – use the color data as indices directly into the colormap. When notscaled, the data are usually integer values ranging from 1 to2-327
