Contour Matrix Charts
(Map View of Regularly Spaced Data)

The contour matrix is chart is a map view of regularly spaced data (i.e., the graph uses data in a matrix layout).

An Example of a Contour Matrix Chart

The contour matrix graph type has the option of filtering matrix data by a moving average, and provides flexible contour customizing tools.

XYZ Contour Charts
(Contouring by Triangulation)

The XYZ contour chart is a map view of irregularly spaced data, displaying inter-related variations in values of three variables.

An Example of an XYZ Contour Chart

The image above shows an XYZ contour image of XYZ data representing subsurface structural elevations of top of Pennsylvanian Lansig-Kansas City Group (source of data: Davis, J. C., 2002).

The left-hand side image above is a contour matrix plot of data generated from the trend surface analysis of the XYZ data displayed on the right-hand side XYZ contour chart.

N-Nearest Neighbors Gridding

To create a continuous surface (which requires an evenly spaced data set) from an unevenly spaced data set, Aabel gridder uses the n-nearest neighbors method, with or without a quadrant or octant constraint on the search pattern.
The right-hand side contour matrix chart below is plotted from gridding of the data used in the X-Y-Z surface plot in the left-hand side image below.

Ternary Contour Charts

This is a 2-D projection of a ternary diagram that displays values of a 4^th dimension using a color scale, contouring by triangulation.

Below, is shown an example of a ternary contour chart with contour lines (left-hand side), and of a ternary contour displaying markers (right-hand side).
