    public class CyclicXYItemRenderer

extends StandardXYItemRenderer

The Cyclic XY item renderer is specially designed to handle cyclic axis. While the standard renderer would draw a line across the plot when a cycling occurs, the cyclic renderer splits the line at each cycle end instead. This is done by interpolating new points at cycle boundary. Thus, correct appearance is restored. The Cyclic XY item renderer works exactly like a standard XY item renderer with non-cyclic axis.

                         CrosshairState crosshairState,
                         int pass)

  Draws the visual representation of a single data item. When using cyclic axis, do not draw a line from right to left when cycling as would a standard XY item renderer, but instead draw a line from the previous point to the cycle bound in the last cycle, and a line from the cycle bound to current point in the current cycle.

  Specified by:
    `drawItem` in interface `XYItemRenderer`

    `drawItem` in class `StandardXYItemRenderer`

    `g2` - the graphics device.
    `state` - the renderer state.
    `dataArea` - the data area.
    `info` - the plot rendering info.
    `plot` - the plot.

    `dataset` - the dataset.
    `series` - the series index.
