Graphrefinement Command Example

Details

Action

Sets the number of values at which a function is evaluated in the process of drawing a graph in a 2D or 3D graph window. In a 3D Graph window, every real-valued function of two variables is drawn with a "domain rectangle" [x1, x2] by [y1, y2]. This domain rectangle is a property of the graphics window and not of the graph . The drawing is done by choosing a pair of sequences of equally spaced points in the abscissa and the ordinate, and drawing an approximation to the graph surface using the images of those points. The number of equal subintervals is the value of the current refinement. The default number of subdivision intervals for the abscissa and the ordinate is 10.

Sets the number of points to be evaluated to 200, when drawing a graph of a function in the selected graph window.
