Public Overloads Function ExportSeriesValues() As DataSet

Visual Basic (Usage)	Copy Code
Dim instance As DataManipulator Dim value As DataSet   value = instance.ExportSeriesValues()

public DataSet ExportSeriesValues()

Return Value

A DataSet object that stores all chart series as DataTable objects. Each data point is stored as a DataRow object.

Exports the data for all series in the Series collection as a returned DataSet object. A DataTable object is created for each chart series and is added to the Tables collection of the DataSet (each DataTable object will have the same name as the series it represents).

Every data point in a series is stored as a DataRow object that is inserted into the Rows collection of the applicable DataTable object.

Each DataTable object will have two or more columns (represented by DataColumn objects): one column for the Y-value of data points and one column per Y-value. All DataColumn objects are named for the value that they represent (e.g. "X", "Y", "Y2", etc.). The column types depends on each Series object's XValueType and YValueType properties. DateTime value types are stored as DateTime columns, String value types are stored as String columns, and all other types are stored as Double columns. Note that a String value type can only be used for the X-values of a chart's data points, and if this is the case it is the AxisLabel property of each data point that determines the stored value.

Empty points by default are not exported. To export empty data points set the IgnoreEmptyPoints property to false (these points will then be stored as DBNull objects in the DataRow object).
