A color map represents a relationship between a range of data values and a set of colors. In this case, spectral colors are used in the color map where red signifies a high value of the variable and blue signifies a low value of the variable. Color maps are useful if the user is interested in the values of the fourth variable on the hull of the surface formed by three variables. The second technique used is a surface plot. A surface plot is a surface that connects all points in a three dimensional space.
Surface plot is useful when it is possible to conceive of a surface that joins all data points.
The third technique used is a color glyph. Glyph representations are made by copying a generic object, usually a sphere, and positioning each copy appropriately and coloring them according to the data associated with that sample point. The visuals generated using the results of the numerical experiments are displayed in either the off-diagonal or the front view. For any visual that particular view is chosen which revealed the most information. Data Explorer provides 14 different views and also provides capabilities for rotation, zooming, panning, roaming, navigation and animation of the generated visuals.
