                 [labels=labelaxes] [grid] [zero]

draws a rectangular frame with corners (X0,Y0), (X1,Y0), (X1,Y1) and (X0,Y1). Subsequently produced graphics is clipped on the borders of the frame. The x- and y-axes are labeled with the titles xtext and ytext, respectively. The parameter tics and labels determines whether tics and numeric labels are drawn. The possible values for ticaxes and labelaxes are:

 off     No labels or tics.
 x       Labels or tics only on the x-axis.
 y       Labels or tics only on the y-axis.
 x,y     Label or tics on both axes (default).

If the option grid is present, a fine grid is drawn. If the option zero is present, fine lines will be drawn along x=0 and y=0 (if they fall within the frame).
