The interactive objects are derived from InterViews interactors (Dulac et al. 1988). The View has functionalities such as zooming, drawing, handling user events, changing display parameters such as clip, tpow, raster or wiggle mode. The IAxis are ``intelligent'' axes which display the user current position inside the view. The axes are attached to the perspective of the view, such that the axes are always consistent with the part of the data being displayed. Table 8 in appendix presents the basic functionalities of the interactive objects.
