Specifying the Figure Pointer
MATLAB indicates the position of the pointer (cursor) within the figure window using a graphical symbol. You can select a pointer from 15 predefined symbols (see table below) or you can define your own symbol. By convention, each of the predefined symbols has a purpose associated with it (although MATLAB enforces no rules for the use of any symbols).
You specify the pointer symbol by setting the value of the figure Pointer property. For example, this statement sets the pointer in the current figure (gcf) to an arrow.
The following table shows the predefined symbols, the associated specifier, and describes typical use.
