In WPF, which property of a Chart control is used to define the data points displayed?

Hi Diana,

Thank you for your question.
In SciChart, the data used to render a particular RenderableSeries is stored as a corresponding DataSeries.
Here you can find more details:
SciChart WPF Documentation – DataSeries Types in SciChart _ WPF Chart Documentation

To get started with SciChart and learn how to use it to create charts, we recommend going through our tutorials:
