.TP 1i
-\f(CWaxis\fR
+\fBaxis\fR
The stripchart widget can display up to four coordinate axes (two
X-coordinate and two Y-coordinate axes), but you can create and use
any number of axes. Axes control what region of data is displayed and
major and minor ticks, and tick labels. Tick labels display the value
of each major tick.
.TP 1i
-\f(CWcrosshairs\fR
+\fBcrosshairs\fR
Cross hairs are used to finely position the mouse pointer in relation
to the coordinate axes. Two perpendicular lines are drawn across the
plotting area, intersecting at the current location of the mouse
pointer.
.TP 1i
-\f(CWelement\fR
+\fBelement\fR
An element represents a set of data points. Elements can be plotted
with a symbol at each data point and lines connecting the points.
The appearance of the element, such as its symbol, line width, and
color is configurable.
.TP 1i
-\f(CWgrid\fR
+\fBgrid\fR

plotting area.

-\f(CWlegend\fR
+\fBlegend\fR
The legend displays the name and symbol of each data element.
The legend can be drawn in any margin or in the plotting area.
.TP 1i
-\f(CWmarker\fR
+\fBmarker\fR
Markers are used annotate or highlight areas of the graph. For
example, you could use a polygon marker to fill an area under a
curve, or a text marker to label a particular data point. Markers
come in various forms: text strings, bitmaps, connected line
segments, images, polygons, or embedded widgets.
.TP 1i
-\f(CWpen\fR
+\fBpen\fR
Pens define attributes (both symbol and line style) for elements.
Data elements use pens to specify how they should be drawn. A data
element may use many pens at once. Here, the particular pen
used for a data point is determined from each element's weight
vector (see the element's \fB\-weight\fR and \fB\-style\fR options).

The widget can generate encapsulated PostScript output. This component
has several options to configure how the PostScript is generated.
