+/**
+ * @fileoverview Creates an interactive, zoomable graph based on a CSV file or
+ * string. Dygraph can handle multiple series with or without error bars. The
+ * date/value ranges will be automatically set. Dygraph uses the
+ * &lt;canvas&gt; tag, so it only works in FF1.5+.
+ * @author danvdk@gmail.com (Dan Vanderkam)
+
+ Usage:
+ <div id="graphdiv" style="width:800px; height:500px;"></div>
+ <script type="text/javascript">
+ new Dygraph(document.getElementById("graphdiv"),
+ "datafile.csv", // CSV file with headers
+ { }); // options
+ </script>
+
+ The CSV file is of the form
+
+ Date,SeriesA,SeriesB,SeriesC
+ YYYYMMDD,A1,B1,C1
+ YYYYMMDD,A2,B2,C2
+
+ If the 'errorBars' option is set in the constructor, the input should be of
+ the form
+ Date,SeriesA,SeriesB,...
+ YYYYMMDD,A1,sigmaA1,B1,sigmaB1,...
+ YYYYMMDD,A2,sigmaA2,B2,sigmaB2,...
+
+ If the 'fractions' option is set, the input should be of the form:
+
+ Date,SeriesA,SeriesB,...
+ YYYYMMDD,A1/B1,A2/B2,...
+ YYYYMMDD,A1/B1,A2/B2,...
+
+ And error bars will be calculated automatically using a binomial distribution.
+
+ For further documentation and examples, see http://dygraphs.com/

- * @fileoverview This file contains the managment of data handlers
- * @author David Eberlein (david.eberlein@ch.sauter-bc.com)
- *
- * The idea is to define a common, generic data format that works for all data
- * structures supported by dygraphs. To make this possible, the DataHandler
- * interface is introduced. This makes it possible, that dygraph itself can work
- * with the same logic for every data type independent of the actual format and
- * the DataHandler takes care of the data format specific jobs.
- * DataHandlers are implemented for all data types supported by Dygraphs and
- * return Dygraphs compliant formats.
- * By default the correct DataHandler is chosen based on the options set.
- * Optionally the user may use his own DataHandler (similar to the plugin
- * system).
- *
- *
- * The unified data format returend by each handler is defined as so:
- * series[n][point] = [x,y,(extras)]
- *
- * This format contains the common basis that is needed to draw a simple line
- * series extended by optional extras for more complex graphing types. It
- * contains a primitive x value as first array entry, a primitive y value as
- * second array entry and an optional extras object for additional data needed.
- *
- * x must always be a number.
- * y must always be a number, NaN of type number or null.
- * extras is optional and must be interpreted by the DataHandler. It may be of
- * any type.
- *
- * In practice this might look something like this:
- * default: [x, yVal]
- * errorBar / customBar: [x, yVal, [yTopVariance, yBottomVariance] ]

- * @fileoverview Description of this file.
- * @author danvk@google.com (Dan Vanderkam)
- *
- * A ticker is a function with the following interface:
- *
- * function(a, b, pixels, options_view, dygraph, forced_values);
- * -> [ { v: tick1_v, label: tick1_label[, label_v: label_v1] },
- * { v: tick2_v, label: tick2_label[, label_v: label_v2] },
- * ...
- * ]
- *
- * The returned value is called a "tick list".
- *
- * Arguments
- * ---------
- *
- * [a, b] is the range of the axis for which ticks are being generated. For a
- * numeric axis, these will simply be numbers. For a date axis, these will be
- * millis since epoch (convertable to Date objects using "new Date(a)" and "new
- * Date(b)").
- *
- * opts provides access to chart- and axis-specific options. It can be used to
- * access number/date formatting code/options, check for a log scale, etc.
- *
- * pixels is the length of the axis in pixels. opts('pixelsPerLabel') is the
- * minimum amount of space to be allotted to each label. For instance, if
- * pixels=400 and opts('pixelsPerLabel')=40 then the ticker should return
- * between zero and ten (400/40) ticks.
- *
- * dygraph is the Dygraph object for which an axis is being constructed.
- *
- * forced_values is used for secondary y-axes. The tick positions are typically
- * set by the primary y-axis, so the secondary y-axis has no choice in where to
- * put these. It simply has to generate labels for these data values.
- *
- * Tick lists
- * ----------
- * Typically a tick will have both a grid/tick line and a label at one end of
- * that line (at the bottom for an x-axis, at left or right for the y-axis).
- *
- * A tick may be missing one of these two components:
- * - If "label_v" is specified instead of "v", then there will be no tick or
- * gridline, just a label.
- * - Similarly, if "label" is not specified, then there will be a gridline
- * without a label.
- *
- * This flexibility is useful in a few situations:
- * - For log scales, some of the tick lines may be too close to all have labels.
- * - For date scales where years are being displayed, it is desirable to display
- * tick marks at the beginnings of years but labels (e.g. "2006") in the
- * middle of the years.

- * @author danvdk@gmail.com (Dan Vanderkam)
-
- Usage:
- <div id="graphdiv" style="width:800px; height:500px;"></div>
- <script type="text/javascript">
- new Dygraph(document.getElementById("graphdiv"),
- "datafile.csv", // CSV file with headers

- </script>
-
- The CSV file is of the form
-
- Date,SeriesA,SeriesB,SeriesC
- YYYYMMDD,A1,B1,C1
- YYYYMMDD,A2,B2,C2
-
- If the 'errorBars' option is set in the constructor, the input should be of
- the form
- Date,SeriesA,SeriesB,...
- YYYYMMDD,A1,sigmaA1,B1,sigmaB1,...
- YYYYMMDD,A2,sigmaA2,B2,sigmaB2,...
-
- If the 'fractions' option is set, the input should be of the form:
-
- Date,SeriesA,SeriesB,...
- YYYYMMDD,A1/B1,A2/B2,...
- YYYYMMDD,A1/B1,A2/B2,...
-
- And error bars will be calculated automatically using a binomial distribution.
