requestZoom
protected abstract void requestZoom(double[][] bounds)
Invoked when the user indicates by mouse gestures that a zoomed view is wanted. The elements of thebounds
array are 2-elementdouble[]
arrays giving (lower, upper) bounds of the range along each axis which is required. A null element indicates that no zooming along that axis is required. Boundary values are in data coordinates.- Parameters:
bounds
