Identifies the link to the dataset where the data-aware chart finds its data. Use the DataSource property to set the TDataSource object where the data-aware chart should fetch its data. Each record of the dataset corresponds to one chart value item in the chart's collection.
The DataFieldXXX properties specifies which TField objects of the dataset are used to populate the corresponding properties in the chart value. Any chart value property that doesn't have a TField linked to it uses its defaults. However, you can use the
OnGetChartValue event to change any aspect of a chart value after its field values have been fetched from the dataset.
