Figure 1: Supported Series

The currently supported series are:

• SparkAreaSeries
• SparkBarSeries
• SparkLineSeries
• SparkScatterSeries
• SparkWinLossSeries

The SparkAreaSeries, SparkBarSeries, and SparkWinLossSeries expose the BaselineValue property defining a value on the vertical axis determining how the view will be divided into top and bottom halves. By default 0 is considered as the base line. The property is extremely useful in the SparkWinLoss series where one can define a threshold different than 0 to indicate wins and losses.
