The data source field(s) to which to bind data point(s). Note that a comma can be embedded as part of a column name, by using a double comma.
This method binds the Y-values of the data points in the collection to the specified fields(s) of the data source.
To bind only to the first field in a data source, use the DataBindY method.
You can bind to several fields by setting the yFields parameter to multiple field names that are comma-separated. Note that the first field will be used for the data point's first Y-value, the second named field will be used for the data point's second Y-value, and so forth.
If Y-values are not provided by the data source, or the wrong number of values are provided, an exception will be thrown.
The following is a list of objects that you can use as the data source:
DataView
Data readers (SQL, OleDB)
Arrays
Lists
All other objects that use the IEnumerable<'T> interface.
