/**
 * Represents a chart that uses cartesian coordinates. A cartesian chart have two directions, X direction and Y direction. The series and axes are coordinated along these
 * directions. By default the x direction is horizontal and y direction is vertical, You can swap the by setting flipXY config to true.
 * <p>
 * Cartesian series often treats x direction an y direction differently. In most cases, data on x direction are assumed to be monotonically increasing. Based on this property,
 * cartesian series can be trimmed and summarized properly to gain a better performance.
