Series.Area Spline - Using Multiple Series
You can add additional series to the chart by adding additional Series elements:
The example above shows two Series, one for each year. A legend can also be added very easily.
The example above shows the two Series elements, their datalayers, and an X-Axis element used to produce the previous chart. You can adjust which series appears "in front" of the other in the chart by changing the order of the Series elements in the definition. Setting the Series elements' Legend Label attribute will automatically cause the legend to be displayed.
When using multiple series, you may be able to reduce the number of data queries and improve performance by using local data to read all of the data once, see Datalayers. Then, link its datalayer to share it to the series, see Link Datalayers. At each Series element, link its datalayer to the shared Local Data datalayer and filter the datato meet the needs of each individual series.
You can combine different types of Series elements, for example, Series.Area Spline and Series.Bar, to produce combinations of visualizations.
