One embodiment of the present invention provides a system for viewing plurality of objects on a display that allows a user to zoom on a non-positional display attribute of the plurality of objects. The system operates by receiving a value for a mapped attribute for an object as well as a value for a zooming parameter for the non-positional display attribute. The system maps the mapped attribute to the non-positional display attribute for the object by computing a function of the value of the mapped attribute and the zooming parameter to produce a value for the non-positional display attribute. If the value for the zooming parameter changes in a first direction, the function maps a narrower range of mapped attribute values to prominent display attribute values. If the value for the zooming parameter changes in a second direction, the function maps a wider range of mapped attribute values to prominent display attribute values. Next, the system outputs the object to the display using the non-positional display attribute. In one embodiment of the present invention, the value for the zooming parameter is received from the user through a data input device, so that the user can adjust the zooming parameter. This allows the user to narrow or widen a range of mapped attributes that are displayed with prominent display attribute values.
