This GUI allows users to control the pcp tour by simply
moving and clicking their mouses. The PCP tour is the
animation of nD tour path with a parallel coordinates
plot. The Variable Selection checkboxes contains all the
numeric variables, and at least three of them need to be
checked to make the display work. All the categorical
variables go to the Class Seclection box. We should
select the class variable by double clicking the variable
names. Color isn't implemented with the pcp tour yet. The
Tour Type radio buttons contains four different tour
types. They are the Grand Tour, Little Tour, Local Tour
and Guided Tour. We can only choose one type a time. For
the Guided Tour, we need to choose an index from the
droplist to specify which particular search type is
desired. The default index would be holes. For tour type
Guided(lda_pp) and Guided(pda_pp), we also need to
specify class variable first, and the Guided(pda_pp) is
also controlled by another parameter, lambda. Lambda
ranges from 0 to 1, with default at 0.02. A value of 0
will make the tour operate like Guided(lda_pp). The
Choose Dimension radio buttons allow us to choose the
dimension number n to animate a nD pcp tour. Dimension
number of pcp tour is the axes number of the parallel
coordinates. The Speed slider can control the speed of
the nD tour. Simply dragging the mouse along the slider,
changes the speed from slow to fast. The Pause check box
allow users to pause the dynamic nD tour and have a close
examination on the details. The Apply button allows users
to update the nD tour, when it doesn't automatically
update. The Quit button allows users to close thie GUI
window. The Help button provides information about the
tour and also what this GUI can do. Tooltips will pop up
when the mouse is moved over the GUI, which give hints
about the functionality of the different GUI elements.
