Use the SeriesBrush property to specify the brush to be used for drawing the data series:
CopyDisplaying multiple data sets with different brushes<ms:Chart> <ms:LineSeries ItemsSource="{Binding PredictedSales}" SeriesBrush="Navy" /> </ms:Chart>
SeriesBrush is a per-series property so you can use different brushes for different data sets.
Some series types have additional styling properties which you can use to further customize the appearance of the chart. For example, line and area series have a LineStyle property which you can use to style all aspects of the Path object used to render the line, such as options for width, mitering and dash style. BarSeries has a Brushes property which you can use to apply different brushes to the bars in the same series.
