Class TimeScaleCalc

java.lang.Object
  edu.sc.seis.fissuresUtil.display.TimeScaleCalc

All Implemented Interfaces:

TimeListener, ScaleMapper, java.util.EventListener

public class TimeScaleCalc
extends java.lang.Object
implements ScaleMapper, TimeListener

TimeScaleCalc takes the total pixels of a given seismogram along with its beginning and ending times to make divisions that are decently human friendly for the time axis. Created: Thu May 16 13:36:24 2002

Method Detail

calculateTicks

public void calculateTicks()

setTotalPixels

public void setTotalPixels(int totalPixels)

getTotalPixels

public int getTotalPixels()

read the number of pixels allocated for this scale;

Specified by:

getTotalPixels in interface ScaleMapper

Returns:

setTimes

public void setTimes(MicroSecondDate beginTime,
                     MicroSecondDate endTime)

getLabel

public java.lang.String getLabel(int i)

Description copied from interface: ScaleMapper

Gets the label if there is one for the ith tick. If there is no label then a empty string should be returned instead of a null.

Specified by:

getLabel in interface ScaleMapper

Parameters:

i - the current tick

getAxisLabel

public java.lang.String getAxisLabel()

Specified by:

getAxisLabel in interface ScaleMapper

getPixelLocation

public int getPixelLocation(int i)

Description copied from interface: ScaleMapper

Gets the pixel location for the ith tick.

Specified by:

getPixelLocation in interface ScaleMapper

Parameters:

i - the current tick

getNumTicks

public int getNumTicks()

Description copied from interface: ScaleMapper

Gets the total number of ticks.

Specified by:

getNumTicks in interface ScaleMapper

isLabelTick

public boolean isLabelTick(int i)

Parameters:

i - the current tick

isMajorTick

public boolean isMajorTick(int i)

Description copied from interface: ScaleMapper

True if the ith tick is a major tick. This could be used by the plotting component to draw major tick longer or thicker.

Specified by:

isMajorTick in interface ScaleMapper

Parameters:

i - the current tick

updateTime

public void updateTime(TimeEvent event)

Specified by:

updateTime in interface TimeListener
