<P> <TT>SYNOPSIS: <BR> &#92;dottedline[<I>optional dotcharacter</I>]&#123;<I>dotgap in units</I>&#125;(<I>x</I><SUB>1</SUB>,<I>y</I><SUB>1</SUB>)(<I>x</I><SUB>2</SUB>,<I>y</I><SUB>2</SUB>)...(<I>x</I><SUB>n</SUB>,<I>y</I><SUB>n</SUB>)</TT>

<P> The above command connects the specified points by drawing a dottedline between each pair of coordinates. At least two points must be specified. The dotted line is drawn with inter-dot gap as specified in the second argument (in unitlengths). Note that since integral number of dots have to be plotted, the interdot-gap may not necessarily be exactly as specified, but very close. It really doesn't matter in visual appearance except when the length of dottedline is very small. By default, a little square (<code></code>, described later) is used as the dot, and can be changed by optionally specifying another character. The thickness of dots is governed by currently effective <code> </code>, <code> </code> or <code> ...</code> declaration when the default character is used. Note that some characters such as ``*'' in roman font do not come out centered, although most other characters do.

<P> One can obtain a <I>solid line</I> by specifying a very small inter-dot gap. Since L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X provides for only finite number of slopes for drawing lines, this gives a general way of making lines with arbitrary slopes. However, if <I>solid lines</I> are made using above technique, there is a good chance T<SMALL>E</SMALL>X will run out of memory, hence it is suggested that this command be used only for ``dotted'' lines. Another, much more efficient, way of making solid lines is described later in the section on <code></code>.

<P> Each ``dot'' in the dottedline is plotted as a centered object, including those at the end points. Thus, a dottedline with a large-sized <I>dotcharacter</I> may appear to be longer although, technically speaking, correct. To clarify the point, below are three lines of equal length and, in the case of dottedlines, with equal spacing:
