3.3 Components and Attributes of the Axes

The coordinate axes drawn by LLA have the following components. (The names of the subroutines which draws the component are shown in parentheses.)
1.
Line segment for the axes (UXPAXS/UYPAXS)
2.
Tick Marks (UXPTMK/UYPTMK)
3.
Label
4.
Title (UXPTTL/UYPTTL)



The components have the following attributes.

1.
Line segment for the axes

a. The line index of a line segment <ISLCT>

2.
Tick Marks
a. The length of a tick mark <ISLCT>
b. The line index for the line of a tick mark <ISLCT>

3.
Label
a. The character height <ISLCT>
b. The angle of rotation of the text <CSIDE>
c. The centering option of the text <CSIDE>
d. The line index for the lines of the text <ISLCT>

4.
Title
a. The character height <ISLCT>
b. The angle of rotation of the text <CSIDE>
c. The centering option of the text <Argument>
d. The line index for the lines of the text <ISLCT>
The methods for specifying these attributes and the definitions of <ISLCT>, <CSIDE>, and  <argument> will be given in the next section.



When the parameters for the coordinate axes are not set by 'U'ser, the label and title will always be drawn on the outside of the window. When set by  'U'ser, the label and title will be drawn on the side of the axes specified by the internal variable 'IFLAG' (See Section 3.8.3.)
