Marks, with the exception of + * the root panel, are not typically constructed directly; instead, they are + * added to a panel or an existing mark via {@link pv.Mark#add}. + * + * @class Represents a data-driven graphical mark. The <tt>Mark</tt> class is + * the base class for all graphical marks in Protovis; it does not provide any + * specific rendering functionality, but together with {@link Panel} establishes + * the core framework. + * + * <p>Concrete mark types include familiar visual elements such as bars, lines + * and labels. Although a bar mark may be used to construct a bar chart, marks + * know nothing about charts; it is only through their specification and + * composition that charts are produced. These building blocks permit many + * combinatorial possibilities. + * + * <p>Marks are associated with <b>data</b>: a mark is generated once per + * associated datum, mapping the datum to visual <b>properties</b> such as + * position and color. Thus, a single mark specification represents a set of + * visual elements that share the same data and visual encoding. The type of + * mark defines the names of properties and their meaning. A property may be + * static, ignoring the associated datum and returning a constant; or, it may be + * dynamic, derived from the associated datum or index. Such dynamic encodings + * can be specified succinctly using anonymous functions. Special properties + * called event handlers can be registered to add interactivity. + * + * <p>Protovis uses <b>inheritance</b> to simplify the specification of related + * marks: a new mark can be derived from an existing mark, inheriting its + * properties. The new mark can then override properties to specify new + * behavior, potentially in terms of the old behavior. In this way, the old mark + * serves as the <b>prototype</b> for the new mark. Most mark types share the + * same basic properties for consistency and to facilitate inheritance. + * + * <p>The prioritization of redundant properties is as follows:<ol> + * + * <li>If the <tt>width</tt> property is not specified (i.e., null), its value + * is the width of the parent panel, minus this mark's left and right margins; + * the left and right margins are zero if not specified. + * + * <li>Otherwise, if the <tt>right</tt> margin is not specified, its value is + * the width of the parent panel, minus this mark's width and left margin; the + * left margin is zero if not specified. + * + * <li>Otherwise, if the <tt>left</tt> property is not specified, its value is + * the width of the parent panel, minus this mark's width and the right margin. + * + * </ol>This prioritization is then duplicated for the <tt>height</tt>, + * <tt>bottom</tt> and <tt>top</tt> properties, respectively. + * + * <p>While most properties are <i>variable</i>, some mark types, such as lines + * and areas, generate a single visual element rather than a distinct visual + * element per datum. With these marks, some properties may be <b>fixed</b>. + * Fixed properties can vary per mark, but not <i>per datum</i>! These + * properties are evaluated solely for the first (0-index) datum, and typically + * are specified as a constant. However, it is valid to use a function if the + * property varies between panels or is dynamically generated. + * + * <p>See also the <a href="../../api/">Protovis guide</a>. + */ +pv.Mark = function() { + /* + * TYPE 0 constant defs + * TYPE 1 function defs + * TYPE 2 constant properties + * TYPE 3 function properties + * in order of evaluation! + */ + this.$properties = []; +}; + +/** @private TOOD */ +pv.Mark.prototype.properties = {}; + +/** + * @private Defines and registers a property method for the property with the + * given name.

The return value of the function is used as the + * computed property value. The context of the function (<tt>this</tt>) is this + * mark.

These function similarly to + * <tt>Number</tt>, except perform a root and log scale, respectively. + * + * @param {function} f the new sizing function. + * @function + * @name pv.Layout.treemap.prototype.size + * @returns {pv.Layout.treemap} this. + */ + mark.size = function(f) { + sizeof = f; + return this; + }; + + return mark; +}; + return pv;}();/* + * Parses the Protovis specifications on load, allowing the use of JavaScript + * 1.8 function expressions on browsers that only support JavaScript 1.6. + * + * @see pv.parse + */ +pv.listen(window, "load", function() { + var scripts = document.getElementsByTagName("script"); + for (var i = 0; i < scripts.length; i++) { + var s = scripts[i]; + if (s.type == "text/javascript+protovis") { + try { + pv.Panel.$dom = s; + window.eval(pv.parse(s.textContent || s.innerHTML)); // IE + } catch (e) { + pv.error(e); + } + delete pv.Panel.$dom; + } + } + }); |
