|void area2d(xinch, yinch)||BPLT.C||Level 2|
|float xinch||The length of the x axis in inches (or cm), as measured on the full-page output.|
|float yinch||The length of the y axis in inches (or cm), as measured on the full-page output.|
|area2d() defines the lengths of the x and y axes.
By default, GraphiC will center the plot based on the call to area2d() with allowances for any labels that are to be plotted. If the dimensions specified do not allow room for the labels, the plot will be resized and a warning message will be placed in the file GRAPHIC.ERR. Use plotabsolute() to prevent GraphiC from resizing your plot. Most x-y plots should have a call to area2d(), but if you leave it out, GraphiC will use a default value.
