alpha
Set transparency properties for objects in current axes Syntax alpha alpha(face_alpha) alpha(alpha_data) alpha(alpha_data) alpha(alpha_data) alpha(alpha_data_mapping) alpha(object_handle,value) Description alpha sets one of three transparency properties, depending on what arguments you specify with the call to this function. FaceAlpha alpha(face_alpha) sets the FaceAlpha property of all image, patch, and surface objects in the current axes. You can set face_alpha to A scalar — Set the FaceAlpha property to the specified value (for images, set the AlphaData property to the specified value). 'flat' — Set the FaceAlpha property to flat. 'interp' — Set the FaceAlpha property to interp. 'texture' — Set the FaceAlpha property to texture. 'opaque' — Set the FaceAlpha property to 1. 'clear' — Set the FaceAlpha property to 0. See Specifying a Single Transparency Value for more information. AlphaData (Surface Objects) alpha(alpha_data) sets the AlphaData property of all surface objects in the current axes. You can set alpha_data to A matrix the same size as CData — Set the AlphaData property to the specified values. 'x' — Set the AlphaData property to be the same as XData. 'y' — Set the AlphaData property to be the same as YData. 'z' — Set the AlphaData property to be the same as ZData. 'color' — Set the AlphaData property to be the same as CData. 'rand' — Set the AlphaData property to a matrix of random values equal in size to CData. AlphaData (Image Objects) alpha(alpha_data) sets the AlphaData property of all image objects in the current axes. You can set alpha_data to A matrix the same size as CData — Set the AlphaData property to the specified value. 'x' — Ignored. 'y' — Ignored. 'z' — Ignored. 'color' — Set the AlphaData property to be the same as CData. 'rand' — Set the AlphaData property to a matrix of random values equal in size to CData. FaceVertexAlphaData (Patch Objects) alpha(alpha_data) sets the FaceVertexAlphaData property of all patch objects in the current axes. You can set alpha_data to A matrix the same size as FaceVertexCData — Set the FaceVertexAlphaData property to the specified value. 'x' — Set the FaceVertexAlphaData property to be the same as Vertices(:,1). 'y' — Set the FaceVertexAlphaData property to be the same as Vertices(:,2). 'z' — Set the FaceVertexAlphaData property to be the same as Vertices(:,3). 'color' — Set the FaceVertexAlphaData property to be the same as FaceVertexCData. 'rand' — Set the FaceVertexAlphaData property to random values. See Mapping Data to Transparency for more information. AlphaDataMapping alpha(alpha_data_mapping) sets the AlphaDataMapping property of all image, patch, and surface objects in the current axes. You can set alpha_data_mapping to 'scaled' — Set the AlphaDataMapping property to scaled. 'direct' — Set the AlphaDataMapping property to direct. 'none' — Set the AlphaDataMapping property to none. alpha(object_handle,value) sets the transparency property only on the object identified by object_handle.
