A cursor (like a grid or a scale) can be displayed on top of (IlvDrawAbove) or underneath (IlvDrawBelow) the graphical representations of data in a chart. By default, a cursor will be displayed on top of the graphical representations. However, the drawing order can be changed for a given cursor by means of the setDrawOrder method.

If no palette is defined to draw the cursor, the palette that will be used by default is the one defined for the axis of the scale with which the cursor is associated.

The axis mark displays the defined cursor label, if it exists. This label is returned by the getLabel method. However, the axis mark directly displays the data value for which the cursor is drawn. This data value is returned by the getValue method.

To speed up the drawing process when the cursor is used as a dynamic mark (for example, when using it in a crosshair), you can specify that the delimiter is to be drawn in XOR mode by using the drawGhost method.
