public interface Measurable
extends Drawable

A Measurable object returns min and max values for its x and y extent. This interface is used to autoscale the x and y axes on a drawing panel. Minimum and maximum values may NOT be valid if isMeasured returns false. Objects that store data, for example, usually return zero if data is null. Copyright: Copyright (c) 2005

Method Summary

Modifier and Type	Method	Description
double	getXMax()	Gets the maximum x needed to draw this object.
double	getXMin()	Gets the minimum x needed to draw this object.
double	getYMax()	Gets the maximum y needed to draw this object.
double	getYMin()	Gets the minimum y needed to draw this object.
boolean	isMeasured()	Determines if information is available to set min/max values.

Methods inherited from interface org.opensourcephysics.display.Drawable

draw

Method Detail

getXMin

double getXMin()

Gets the minimum x needed to draw this object.

Returns:

minimum

getXMax

double getXMax()

Gets the maximum x needed to draw this object.

Returns:

maximum

getYMin

double getYMin()

Gets the minimum y needed to draw this object.

Returns:

minimum

getYMax

double getYMax()

Gets the maximum y needed to draw this object.

Returns:

minimum

isMeasured

boolean isMeasured()

Determines if information is available to set min/max values. Objects that store data should return false if data is null.

Returns:

true if min/max values are valid
