Using the Lisp Inspector with DUSI

If the X-AXIS object in the OV is selected, various things can be done with it. Below, we show the results that follow from pressing the Highlight Object and Inspect Object buttons.

Pressing the Inspect Object button in the OV causes a Lisp Inspector window to open, inspecting whatever object is highlighted in the OV stack. Pressing the Highlight Object button causes all the primitive objects which are constituents of the highlighted stack item to be highlighted in color (in red) in the DV window.

In the bottom DV window, the components that make up the X-AXIS object are highlighted. These include the axis line, the axis label, "Time (sec)", the tick marks and their numerical labels, and the annotation text and arrow. The contents of the X-AXIS CLOS object are shown in the Lisp Inspector window above the DV. The object has many slots, but the primary ones of interest here are the last five X-AXIS-LINE through X-TEXT, which are the constituents of the X-AXIS production in the grammar.
