This GUI allows users to control the andrews tour by
simply moving and clicking their mouses. 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 Selection box. We should select the class variable
by double clicking the variable names. 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 tour path with
Andrews' curves. Dimension n ranges from 2 to the total
number of the numeric variables of this dataset, and the
default dimension is 2. Andrews' curves are static
methods for displaying 2 or more variables. Here Andrews'
curves are used to display projections of the full data.

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.
