setRounding(roundMin, roundMax)

Controls whether to round the ends of the axis to align with tick positions.

For example, if the axis is from 0.33 - 9.7, ChartDirector may round it to 0 - 10 so that the ends 0 and 10 are properly aligned with the ticks.

By default, ChartDirector will round the axis ends for the y-axis, but not for the x-axis. An exception is a chart containing a scatter layer, where both x and y axes will be rounded.

Argument	Default	Description
roundMin	(Mandatory)	A true (non-zero) value means the lesser end of the axis should be rounded to align with tick positions. A false (zero) value means no rounding.
roundMax	(Mandatory)	A true (non-zero) value means the greater end of the axis should be rounded to align with tick positions. A false (zero) value means no rounding.
