Color By

Specify what aspect of the item is to be rendered, from one of three mutually exclusive groups (only one selection from any group is active at one time): textual values, numeric values, and vector quantities. If a Vector Qty is chosen, an additional field is added to specify whether a component ($$x$$, $$y$$, or $$z$$) or the magnitude (mag) of the vector should be rendered.

Selecting -->Add Prop at the bottom of a selector will provide a dialog that allows the user to specify a new property to add to the list (and make it the active color by selection).

The labels ATTRIBUTE and PROPERTY on a selector do nothing; these are provided to visually differentiate the two groups.

 extra Colors by extra variable. An additional field is supplied to identify the variable by its index. group Colors by group. An additional field is supplied to specify the slot index. The default setting is Any (which occupies index position 0 on the spinbox).
 extra Colors by extra variable. An additional field is supplied to identify the variable by its index. porosity Color by the porosity.
 extra Colors by extra variable. An additional field is supplied to identify the variable by its index. force Color by the force.
