Figure PropertiesPointerShapeHotSpot2-element vectorPointer active area. A two-element vector specifying the row and columnindices in the PointerShapeCData matrix defining the pixel indicating thepointer location. The location is contained in the CurrentPoint property andthe root object’s PointerLocation property. The default value is element (1,1),which is the upper-left corner.Positionfour-element vectorFigure position. This property specifies the size and location on the screen ofthe figure window. Specify the position rectangle with a four-element vector ofthe form:rect = [left, bottom, width, height]where left and bottom define the distance from the lower-left corner of thescreen to the lower-left corner of the figure window. width and height definethe dimensions of the window. See the Units property for information on theunits used in this specification. The left and bottom elements can be negativeon systems that have more than one monitor.You can use the get function to obtain this property and determine the positionof the figure and you can use the set function to resize and move the figure toa new location.Rendererpainters | zbufferRendering method used for screen and printing. This property enables you toselect the method used to render MATLAB graphics. The choices are:• painters – MATLAB’s original rendering method is faster when the figurecontains only simple or small graphics objects.• zbuffer – MATLAB draws graphics object faster and more accuratelybecause objects are colored on a per pixel basis and MATLAB renders onlythose pixels that are visible in the scene (thus eliminating front-to-backsorting errors). Note that this method can consume a lot of system memoryif MATLAB is displaying a complex scene.• OpenGL – OpenGL is a renderer that is available on many computer systems.This renderer is generally faster than painters or zbuffer and in some casesenables MATLAB to access graphics hardware that is available on somesystems.2-181
