The MM Contours ActiveX ControlThe MM Contours ActiveX control is designed to visualize the data given in the random set of points on a plane. Each point is defined by its coordinates x and y and the value v – this is often called as XYZ data. The data are not obliged to be given at nodes of a regular grid, as it frequently is required in similar tools. The MM Contours control provides the algorithm of construction of a regular grid from your irregular data. The control can visualize the data in the form of contouring and/or shading. The labeling of local extrema is also included.
