Box.setZOrder

Sets the z-order (drawing order) for custom box objects.

The setZOrder method of the Box object only applies to custom objects created using BaseChart.addText. Box objects generated by ChartDirector, such as axes labels, data labels, etc., will have their z-order fixed by ChartDirector.

ChartDirector will draw objects in ascending z-order. That means objects with larger z-order will be drawn later, and hence will be on the top of the chart.

The following constants represents the z-order of various ChartDirector objects. You may use these constants to determine the ordering of the object relative to these ChartDirector objects.

Constant	Value	Description
ChartBackZ	0x100	The z-order of the chart background. Objects at this z-order will be painted on the chart background.
ChartFrontZ	0xffff	The z-order of the front of the chart. Objects at this z-order will appear on top of all chart objects.
PlotAreaZ	0x1000	The z-order of the plot area background. Objects at this z-order will be painted on the plot area background but behind other plot area objects (such as grid lines).
GridLinesZ	0x2000	The z-order of the grid lines. Objects at this z-order will be painted after painting the grid lines.
