+     *
+     * 'orientation' Specifies the paper orientation, default is 'portrait' and

+     * 'creator' The creator tag of the PDF/graph

+ * Main class for the graph creation.
+ *
+ * This is the main class, it manages the canvas and performs the final output
+ * by sequentialy making the elements output their results. The final output is
+ * handled using the {@link Image_Canvas} classes which makes it possible
+ * to use different engines (fx GD, PDFlib, libswf, etc) for output to several
+ * formats with a non-intersecting API.
+ *
+ * This class also handles coordinates and the correct managment of setting the
+ * correct coordinates on child elements.

+     * If passing the 3 parameters they are defined as follows:'
+     * 
+     * Fx.:
+     * 
+     * $Graph =& new Image_Graph(400, 300);
+     * 
+     * or using the factory method:
+     * 
+     * $Graph =& Image_Graph::factory('graph', array(400, 300));
+     * 
+     * This causes a 'png' canvas to be created by default. 
+     * 
+     * Otherwise use a single parameter either as an associated array or passing
+     * the canvas along to the constructor:
+     *
+     * 1) Create a new canvas with the following parameters:
+     *
+     * 'canvas' - The canvas type, can be any of 'gd', 'jpg', 'png' or 'svg'
+     * (more to come) - if omitted the default is 'gd'
+     *
+     * 'width' - The width of the graph
+     *
+     * 'height' - The height of the graph
+     * 
+     * An example of this usage:
+     * 
+     * $Graph =& Image_Graph::factory('graph', array(array('width' => 400,
+     * 'height' => 300, 'canvas' => 'jpg')));
+     * 
+     * NB! In thïs case remember the "double" array (see {@link Image_Graph::
+     * factory()})
+     * 
+     * 2) Use the canvas specified, pass a valid Image_Canvas as
+     * parameter. Remember to pass by reference, i. e. &amp;$canvas, fx.:
+     *
+     * $Graph =& new Image_Graph($Canvas);
+     *
+     * or using the factory method:
+     *
+     * $Graph =& Image_Graph::factory('graph', $Canvas));
+     *
+     * @param mixed $params The width of the graph, an indexed array
+     * describing a new canvas or a valid {@link Image_Canvas} object
+     * @param int $height The height of the graph in pixels
+     * @param bool $createTransparent Specifies whether the graph should be

+ * Format data as looked up in an array.
+ *
+ * ArrayData is useful when a numercal value is to be translated to
+ * something thats cannot directly be calculated from this value, this could for
+ * example be a dataset meant to plot population of various countries. Since x-
+ * values are numerical and they should really be country names, but there is no
+ * linear correlation between the number and the name, we use an array to 'map'
+ * the numbers to the name, i.e. $array[0] = 'Denmark'; $array[1] = 'Sweden';
+ * ..., where the indexes are the numerical values from the dataset. This is NOT
+ * usefull when the x-values are a large domain, i.e. to map unix timestamps to
+ * date-strings for an x-axis. This is because the x-axis will selecte arbitrary
+ * values for labels, which would in principle require the ArrayData to hold
+ * values for every unix timestamp. However ArrayData can still be used to solve
+ * such a situation, since one can use another value for X-data in the dataset
+ * and then map this (smaller domain) value to a date. That is we for example
+ * instead of using the unix-timestamp we use value 0 to represent the 1st date,
+ * 1 to represent the next date, etc.

+ * displayed in context of the primary axis' label interval - meaning that a
+ * grid for an Y-axis displays a grid for every label on the y-axis (fx. a {@link
+ * Image_Graph_Grid_Lines}, which displays horizontal lines for every label on
+ * the y-axis from the x-axis minimum to the x-axis maximum). You should always
+ * add the grid as one of the first elements to the plotarea. This is due to the
+ * fact that elements are 'outputted' in the order they are added, i.e. if an
+ * grid is added *after* a chart, the grid will be displayed on top of the chart
+ * which is (probably) not desired.

+In this folder the files for the Image_Graph_Plot_Map are located. They should be the

+

+[map name].txt
+
+The [map name].png (fx. europe.png) is the actual image presenting the map. The 
+[map name].txt file is the location -> (x,y) conversion table. In this file the
+named locations is written on every line with the x and y coordinates after the
+name (with a TAB), i.e.:
+
+Denmark	10	30
+England	4	30
+
+Where Denmark will be 'located' on (10, 30) on the map, and England at (4, 30).
+
+No maps are released by default due to we want to avoid possible copyright issues.

+ * A map plot is a chart that displays a map (fx. a world map) in the form of  .
+ * png file. The maps must be located in the /Images/Maps folder and a
+ * corresponding .txt files mush also exist in this location where named
+ * locations are mapped to an (x, y) coordinate of the map picture (this text
+ * file is tab separated with 'Name' 'X' 'Y' values, fx 'Denmark 378 223'). The
+ * x-values in the dataset are then the named locations (fx 'Denmark') and the
+ * y-values are then the data to plot. Currently the best (if not only) use is
+ * to combine a map plot area with a {@link Image_Graph_Plot_Dot} using {@link
+ * Image_Graph_Marker_PercentageCircle} as marker.
