-
- Represents a bar: an axis-aligned rectangle that can be stroked and
- filled. Bars are used for many chart types, including bar charts, histograms
- and Gantt charts. Bars can also be used as decorations, for example to draw a
- frame border around a panel; in fact, a panel is a special type (a subclass)
- of bar.
- <p>Bars can be positioned in several ways. Most commonly, one of the four
- corners is fixed using two margins, and then the width and height properties
- determine the extent of the bar relative to this fixed location. For example,
- using the bottom and left properties fixes the bottom-left corner; the width
- then extends to the right, while the height extends to the top. As an
- alternative to the four corners, a bar can be positioned exclusively using
- margins; this is convenient as an inset from the containing panel, for
- example. See <a href="../symbols/pv.Mark.html">pv.Mark</a> for details on the prioritization of redundant
- positioning properties.
- <p>See also the <a href="../../api/Bar.html">Bar guide</a>.

- <div class="description">
- Constructs a new bar anchor with default properties. Bars support five
- different anchors:<ul>
- <li>top
- <li>left
- <li>center
- <li>bottom
- <li>right
- </ul>In addition to positioning properties (left, right, top bottom), the
- anchors support text rendering properties (text-align, text-baseline). Text
- is rendered to appear inside the bar.
- <p>To facilitate stacking of bars, the anchors are defined in terms of their
- opposite edge. For example, the top anchor defines the bottom property, such
- that the bar grows upwards; the bottom anchor instead defines the top
- property, such that the bar grows downwards. Of course, in general it is more
- robust to use panels and the cousin accessor to define stacked bars; see
- <a href="../symbols/pv.Mark.html#scene">pv.Mark#scene</a> for an example.
- <p>Bar anchors also "smartly" specify position properties based on whether
- the derived mark type supports the width and height properties. If the
- derived mark type does not support these properties (e.g., dots), the
- position will be centered on the corresponding edge. Otherwise (e.g., bars),
- the position will be in the opposite side.
