In geometry, the foci (/ËfoÊsaÉª/ ; singular focus) are a pair of special points with reference to which any of a variety of curves is constructed. For example, foci can be used in defining conic sections, the four types of which are the circle, ellipse, parabola, and hyperbola. In addition, foci are used to define the Cassini oval and the Cartesian oval.
While the focus of the line chart is still change in values over time, the focus of an area chart is to highlight the magnitude of values over time. The difference is subtle, but when you need to show things like how many trees have been clear cut from 1990 to 1995 versus 2000 to 2005, the area chart really shines.
