Contour: The contour application contours and performs gradient analysis for two- and three-dimensional, regularly gridded data. Only two-dimensional views are possible however. Three-dimensional data sets can be viewed along X-Y, X-Z, and Y-Z planes. Profile lines along the contoured surface can also be plotted.

This figure shows the results of a grid which has been calculated for the entire rectangular region, but the region not of interest has been masked. The data represents a contaminant plume moving mainly from left to right. A profile line (A-A') is also shown; the concentration profile is displayed two figures down. Click for full size image

Instead of displaying the concentration levels, it is sometimes useful to instead look at the rate of change. This is a gradient map. Click for full size image
With gradients, it is also sometimes useful to monitor the direction of change. With vectors, the magnitude and direction of change can be displayed. Click for full size image
