ChartDirector 6.2 (.NET Edition)

Line Comparison




This example demonstrates filling the area between two lines or curves, as well as a number of advanced chart formatting techniques.

ChartDirector supports filling the area between two lines. The lines can be from a LineLayer, SplineLayer, StepLineLayer, TrendLayer or from an axis Mark. Two colors can be used for filling, depending on which line is on top.

The effects in this example is achieved using the following methods:
