Coord class abstract

Specification of the coordinate.

As in a plane, The count of coordinate dimensions can be 1 or 2 (Which is set by dimCount).

For a 2 dimensions coordinate, the coordinate will have both domain dimension (usually denoted as "x") and measure dimension (usually denoted as "y").

For a 1 dimension coordinate, the coordinate will only have measure dimension, and all points' domain dimensions will be set to dimFill for rendering position.

The coordinate region is the visual boundary rectangle of the coordinate on the chart widget. It is determined by chart size and padding. the coordinate range may be smaller or larger than the region. The range properties of RectCoord and PolarCoord is are define in ratio to coordinate region.
