1.

Function

Fills in the interior of a box graph.

2.

Call

CALL UVBXA (N,X,Y1,Y2)
CALL UHBXA (N,X1,X2,Y)
CALL UVBXAZ(N,X,Y1,Y2,ITP1,ITP2)
CALL UHBXAZ(N,X1,X2,Y,ITP1,ITP2)

Explanation of Parameters

N	(I)	The length of an array.
X, Y	(R(N+1))	Independent variables.
X1, X2, Y1, Y2	(R(N))	The values for the ends of a box.
ITP1, ITP2	(I)	The tone pattern number. When X1<X2 or Y1<Y2, ITP1 is used. When X1>X2 or Y1>Y2, ITP2 is used.

Notes

(a)

When RUNDEF  is specified as X or Y, it is considered that the points dividing the range defined by UUSIDV into N equal sections have been specified. If the defined range is not specified, then the whole window is considered to be the defined range.

(b)

When RUNDEF  is specified as X1, Y1 or X2, Y2, it is considered that the value of the internal variable 'UREF' has been specified. The initial value of 'UREF' is 0.

(c)

The tone pattern used for fill by UVBXA, UHBXA is specified by UUSARP.
