DCL:GRPH2:ULPACK : Logarithmic Coordinate Axis Routines: Explanation of Subroutines

4.3.3 ULSXBL/ULSYBL

1.

Function

Specifies the position to plot the labels.

2.

Call

CALL ULSXBL(BL,NBL)
CALL ULSYBL(BL,NBL)

3.

Explanation of Parameters

BL	(R)	The position of the labels within the range of a single order. The values of the elements must be larger than 1 and smaller than 10. Also, BL(1) must be 1.
NBL	(I)	The length of array BL.

4.

Notes

(a)

When specifying NLBL as 4 in ULXLOG/ULYLOG, the positions of the labels must be specified beforehand using the present routine.

(b)

The length of BL must be less than 9.

(c)

The positions to draw the labels for the X and Y axes can be inquired using the subroutines

ULQXBL(BL,NBL) / ULQYBL(BL,NBL).

(d)

There is a routine for internally inquiring the position to draw the labels: ULXLBL/ULYLBL.
