There are two types of Chart series, a standard and a DB aware variant. 

The Series Component

The essential property is the ‘elements’ property. It represents the data that must be displayed in a chart. The chart type is set to parent; this is for future use to support different chart types in one chart (not supported yet).

It is possible to add the chart series, most handy while developing. In general, you will add the data to the chart by your program. We will discuss that later.

The DBSeries component

This component is similar to the Series component, but it has a few additional properties. The first is the data source that must be bound to a dataset representing the data to be displayed. The fields that are used for the x and y coordinates are set by the ‘data field data’ and ‘data field title’ properties. The ‘elements’ property is also present and allows you to add additional data to the chart.
