To continue exploring this sample data set, close the dialog box of Figure 4 and, from the XDS File Attributes box of Figure 3, choose Cartesian Dicer by left clicking on the diamond next that entry. The XDS Dicer window shown in Figure 7 will be made available for you to continue the exploration of your data set.

Figure 7 Orthogonal Planes Bisecting the Data Set

First select the Palette option of Figure 7 and load or construct a palette that you think will expose some patterns in your data. This step often requires quite a bit of experimentation. Figures 8 through 10 will give you an idea of what you can do with the Cartesian Dicer.

In the Dicer window the X coordinate increases from left to right across the box; Y increases from the base to the top of the box; Z increases from the front face to the rear face of the box. The scroll bars of Figure 7 permit panning over a data set that might be too large to fit in the window. Below and to the right of these scroll bars are three slides that allow for changing the position of a planes perpendicular to the coordinate axes. The slide to the right of the window controls the Y coordinate. The lower left slide controls the X coordinate and the remaining slide varies the Z coordinate. Left clicking in a slide area selects a plane for viewing. Dragging the slide sweeps out a block of planes to be filled with color. Planes where X is constant are displayed with colors from the right third of the displayed palette; planes of constant Y use the middle third of the palette; constant Z planes obtain their colors from the left third of the palette. Occasionally, the palette becomes corrupted and it is necessary to reload it. Figures 8 through 10 will give you an idea of what you can do with the Cartesian Dicer.

To complete this short introduction to XDS, return to the XDS Dicer window and clear any data displayed in the Cartesian Dicer window of Figure 7. Turn on the Dicer option by left clicking on the button next to Dicer. This option permits you to lo ok into your data set in more detail than the previous plane-at-a-time method. Experiment with the X, Y, and Z sliders until you are able to create a visualization similar to that of Figure 11.
