WPAG (Define page limits from the window)

This command defines the limits of the plot page based on the current window size. It is intended to be used after defining a window size based on option 2 of the WDEF command. This allows you to determine the size of a plot based on the data contained in the data buffer. This is particularly useful when plotting line data profiles on a routine basis.

Command Syntax:

WPAG ml,mb,mr,mt

Command Parameters:

ml,mb,mr,mt

the left, bottom, right and top margins in map units. These are the distances from the edges of the currently defined map window to the edge of the drawing area.

The WPAG command can only be used once. It cannot be used if the MDFF, MAPR or PAGE command are used.

Example

The following example reads data from an XYZ file and scales the data window to plot the data. It uses option 2 of the WDEF command to cause the window limits to be adjusted to fit the data based on a horizontal scale of 100 units per plot centimetre. Note that because the vertical scale was not specified in the WDEF command, a vertical scale is determined so that the Z limits (swapped into Y) of the data will be plotted within the 15 centimetre Y window.

This command is part of the MAPPLOT GX.
