DCL:GRPH2:USPACK: Auto-Scaling Routines: Explanation of Subroutines (Coordinate Axis Routines)

7.7.2 USXAXS/USYAXS

1.

Function

Calculates appropriate intervals for the tick marks and labels for the currently set transformation function, and plots a single coordinate axis in the specified position.

2.

Call

CALL USXAXS(CXSIDE)
CALL USYAXS(CYSIDE)

3.

Explanation of Arguments

CXSIDE	(C*1)	The position of the coordinate axis ( 'B'/'T'/'U'). (i)
CYSIDE	(C*1)	The position of the coordinate axis ( 'L'/'R'/'U'). (i)

4.

Notes

(a)

A uniform or logarithmic axis is drawn according to the transformation function number set.

(b)

In the case of a uniform axis, tick marks are almost always placed at both ends of the axis when the maximum and minimum values of the window are rounded by USPFIT.

(c)

Since the title is not drawn by this routine, draw titles using routines such as U[XY]STTL.
