Contour Charts

Aabel 2-D contour charts include:

• X-Y-Z contour by triangulation (map view of irregularly spaced data), displaying inter-related variations in values of three variables
• Contouring by gridding (N-nearest neighbors)
• Contour matrix chart (map view of regularly spaced data) with the option of filtering matrix data by a moving average
• Ternary contour charts (a 2-D projection of a ternary diagram using four variables)
