データは、データ視覚コントロールの中核ですThe Sparkline control can easily bind to any enumerable collection of data values i.e. to any class that implements the IEnumerable interface or the INotifyCollectionChanged interface to support data modification after binding. 

You can populate the sparkline using the Data property.

sparkline.Data = new List<double> { 5, 6, 2, 12 };

Additionally, Sparkline supports a date axis which can be bound to a collection of dates that acts as x-coordinates using the DateAxisData property.

sparkline.DateAxisData = new List<DateTime> { new DateTime(2022, 1, 1), new DateTime(2022, 1, 2), new DateTime(2022, 1, 3) };

For a complete sample on how to bind Sparkline to a data source, see Bind to Data Source section in the Quick Start topic.
