<p>Most charts have two or more axes, but some have none. One
example of a chart with no axis is pie chart. The horizontal axis is
called base axis. The base axis can be category axis or value axis. The
category axis just contains a sequence of labels, while the value axis
-contains numeric values. The vertical axis is an orthogonal axis, and it
-is always a value axis. The BIRT Chart Engine supports one base axis,
-and one or more orthogonal axes, but only one orthogonal axis is
-primary. The series determines how to show data. For example, a bar
+contains numeric or datetime values. The vertical axis is an orthogonal
+axis, and it is always a value axis. The BIRT Chart Engine supports one
+base axis, and one or more orthogonal axes, but only one orthogonal axis
+is primary. The series determines how to show data. For example, a bar
series will show data with a bar graph, and a pie series shows data with
a pie chart. The series definition defines the color palette, label
displaying format, and the associated series. Each axis can have more
