TRSPathChartDataLink Class

Scroll Prev Top Next More

Povide a data-aware link for the RSDBCharts.TRSDBPathChart .

Important Note
Unlike other charts, the path chart fetches data from one record only and creates one value only; it is assumed that one field of the record will hold the entire path.

Note
DataFields holds the field names associated with each dimension in the TRSChartValue internal array plus two. The last index holds the Caption's FieldName. The first index holds the path data

Notes to Callers
Data-aware path charts use the TRSPathChartDataLink to provide a mapping of data field names to their Values dimension. They should expose properties that allow the user to input dataset field names for each dimension of their TRSChartValue.Values property. These field names would be placed in DataFields property.

Namespace: RSDBCharts

	Name	Description
	ChartFieldCount	Returns the number of chart fields (TFields associated with a chart dimension) plus 1 for Caption. (Inherited from RSDBCharts.TRSChartDataLink.)
	ChartFields[Integer]	Returns the DataSet TField associated with the TRSChartValue.Values dimension (Index). The association of TField and Name is specified in the DataFields property. (Inherited from RSDBCharts.TRSChartDataLink.)
	DataChanging	Represents property DataChanging. (Inherited from RSDBCharts.TRSChartDataLink.)
	DataFields[Integer]	Defines the names of the TRSChartValue.Values dimension (Inherited from RSDBCharts.TRSChartDataLink.)
	FieldCount	Returns the number of fields in the DataSet (Inherited from RSDBCharts.TRSChartDataLink.)
	Fields[Integer]	Returns a TField for all the fields in the Dataset (Inherited from RSDBCharts.TRSChartDataLink.)
	OnActiveChanged	Occurs when the Active property of the TRSChartDataLink changes. Write an OnActiveChange event handler to take specific action immediately after the dataset transitions into or out of an active state. OnActiveChange is particularly useful for updating objects to reflect changes that occurred while the dataset was not active, as the object can not respond to events while its TRSChartDataLink is not Active.
	OnDataSetChanged	Occurs when the dataset changed (Inherited from RSDBCharts.TRSChartDataLink.)
	OnGetChartValue	Occurs when the data has changed and the dataset needs a chart value. Use this event to retrieve chart values that cannot be automatically handled by the TRSChartDataLink (Inherited from RSDBCharts.TRSChartDataLink.)
	OnLayoutChanged	Occurs after the layout has changed in a way that affects the representation of the dataset. (Inherited from RSDBCharts.TRSChartDataLink.)
	Parent	Returns the chart that owns the data link (Inherited from RSDBCharts.TRSChartDataLink.)

	Name	Description
	ActiveChanged	Represents method ActiveChanged. (Inherited from RSDBCharts.TRSChartDataLink.)
	DataSetChanged	Represents method DataSetChanged. (Inherited from RSDBCharts.TRSChartDataLink.)
	DataSetScrolled(Integer)	Represents method DataSetScrolled(Integer). (Inherited from RSDBCharts.TRSChartDataLink.)
	DoActiveChanged	Represents method DoActiveChanged. (Inherited from RSDBCharts.TRSChartDataLink.)
	DoDataChanged	Represents method DoDataChanged. (Overrides RSDBCharts.TRSChartDataLink.DoDataChanged.)
	DoDataChanged(TRSChartValueTypeArray)	Represents method DoDataChanged(TRSChartValueTypeArray). (Overrides RSDBCharts.TRSChartDataLink.DoDataChanged(TRSChartValueTypeArray).)
	DoLayoutChanged	Represents method DoLayoutChanged. (Inherited from RSDBCharts.TRSChartDataLink.)
	LayoutChanged	Represents method LayoutChanged. (Inherited from RSDBCharts.TRSChartDataLink.)
	RecordChanged(TField)	Represents method RecordChanged(TField). (Inherited from RSDBCharts.TRSChartDataLink.)

	Name	Description
	OnDataSetScrolled	Occurs when the dataset has finished scrolling (Inherited from RSDBCharts.TRSChartDataLink.)
	OnRecordChanged	Occurs on changes in the current record or field of the DataSource (Inherited from RSDBCharts.TRSChartDataLink.)
