wp

Set the 2D plotting window via problem coordinates.

Synopsis:

wp xmin xmax ymin ymax

Arguments:

xmin

The minimum value to use in the X direction. A real number.

xmax

The maximum value to use in the X direction. A real number.

xmin < xmax

ymin

The minimum value to use in the Y direction. A real number.

ymax

The maximum value to use in the Y direction. A real number.

ymin < ymax

Description:

The wp command sets the 2D plotting window using problem (physical/world) coordinates. This command allows the user to view a subset of a mesh or plot. The rect mode of the winmode command performs the same function, but allows the user to use the mouse for window selection.

wp differs from vp , though the two are similar. vp sets the portion of the window into which to put the plot. Thus its coordinates are in window coordinates. wp determines which part of the problem (mesh) to plot, and so its coordinates are in problem ("physical" or "world") coordinates.

Examples:

wp 0 10 0 10

wp 0. 15. 10. 40.
