AreaChart control in Flex4:

The AreaChart Control is a MX Component. There is no Spark component.
The AreaChart Control represents an area bounded by a line connecting the data values. You can provide the data to the chart by using data provider property. You will use <mx:horizontalAxis> or <mx:verticalAxis> and <mx:Series> in it. You will use xField, yField, displayName and Form property for series. You can use more than one series in it. There are six types of Form for display a chart: segment, step, reverseStep, vertical, horizontal and curve. You can provide color to series using areaFill and areaStroke property. The tag of AreaChart Control is <mx:AreaChart>.
