# Differences Between DataSeries and XYDataSeries

## Content



[DataSeries](/componentone/api/wpf/online-chart/dotnet-framework-api/C1.WPF.C1Chart.4.6.2/C1.WPF.C1Chart.DataSeries.html) has only one logical set of data values - Values(y-values).

In this case x-values are generated automatically(0,1,2...), also you can specify text labels for x-axis using **Data.ItemNames** property.

[XYDataSeries](/componentone/api/wpf/online-chart/dotnet-framework-api/C1.WPF.C1Chart.4.6.2/C1.WPF.C1Chart.XYDataSeries.html) has two sets of data values - Values(y-values) and XValues.
