zoomed
public void zoomed(double[][] bounds) Description copied from class:ZoomRegion

Elements of the parameter array are two-element arrays giving (lower, upper) bounds in one or more dimensions, according to the type of region. The units should normally be dimensionless: a range of (0,1) indicates the same range as is currently contained by the display region. Bounds may be larger or smaller than the (1,0) interval.- Specified by:
