+ * 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.

+ * A grid displayed on the plotarea.
+ *
+ * A grid is associated with a primary and a secondary axis. The grid is
+ * 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.
