TOUR CONTROLS

The Guided Tour window presents a spinning 6-dimensional scatterplot. Initially, the space corresponds to the first 6 variables in your data, and it is spinning in the 3D space defined by the first 3 variables. 

High-dimensional rotation is called a 'tour' of high-dimensional space. The tour is initiated by clicking on the TOUR button. The speed of the tour is controlled by the HSpd and VSpd buttons, which control the speed of rotation of the cloud in the Horizontal and Vertical directions. The minimum speed is zero. Holding down these buttons gradually increases the speed. Note that when the cloud is spinning both horizontally and vertically, the result is a four-dimensional tour which appears as moving points, not as rotation.

The beginning position of the point cloud is the same as that shown in the First Target window. When the horizontal and vertical dimensions are rotated 270 degrees the position is the same as that shown in the Second Target window. Further rotation by 90 degrees brings the cloud back to the First Target position.

The NEW button creates a new 6 dimensional space for a new tour. It does this by using the 3 dimensions of the current position shown in the window as the new 'First Target', and by defining the highest variance 3-dimensional space which is orthogonal to the new First Target as being a new Second Target.

SPIN CONTROLS

The description given in this section is from the general help about spinning plots.  The description also applies to the tour plot, except that the HOME and ROCK buttons have been redefined to work within a six-dimensional context.

The Spin plot presents a three-dimensional scatterplot which you can spin to observe the distribution of your data in three dimensions.

The Up/Dn, C/CC, and L/R buttons at the bottom of the window control spinning direction(the button names mean Up/Down, Clockwise/Counterclockwise and Left/Right). Click on a button to change direction. The SPEED buttons control the speed of spinning. Hold down a button to gradually increase or decrease the speed.

The SPIN button starts and stops rotation. You can also spin the space by using the HAND ROTATE tool (whose cursor is a hand) and dragging your cursor around the space. If your cursor is not a hand, you can get this tool by clicking on the MOUSE button at the top of the window. Finally, you can spin the space by holding down the shift key while you click on the rotate buttons, or while you use the HAND ROTATE tool: The spinning will continue by itself until you click on the SPIN button.

The HOME button returns the space to its original orientation and stops rotation.  The ROCK button reverses the direction of rotation: Repeatedly clicking on this button rocks the space back and forth, giving you a better view of the detailed location of points in the space. The CLIP button clips off garbage that sometimes appears at the edges of the window. Holding down a ZOOM button will gradually zoom the space in or out.

At the top of the window are buttons that give you this help message, turn color on and off, and allow you to change the mouse-mode. In addition, the BOX button allows you to add or remove a three-dimensional box that encompasses the data points.
