Constructor Detail

ObjectXTickLocator

public ObjectXTickLocator(int first,
                          int last,
                          int maxTics)

Pass-through constructor to construct the locator object based on the first and last index on the X axis of objects to be displayed. Constrains ticks to the maximum number.

Parameters:

first - the smallest index to allow

last - the largest index to allow

maxTics - the maximum number of ticks to display

ObjectXTickLocator

public ObjectXTickLocator(int first,
                          int last,
                          int maxTics,
                          boolean forceAll)

Pass-through constructor to construct the locator object based on the first and last index on the X axis of objects to be displayed. Constrains ticks to the maximum number. Setting forceAll allows all indices to be displayed.

Parameters:

first - the smallest index to allow

last - the largest index to allow

maxTics - the maximum number of ticks to display

forceAll - true to display all indices

Method Detail

getTickMarkLocationsAsPairs

public float[] getTickMarkLocationsAsPairs(int y)

Returns an array of x,y pairs. The x value contains an x tick location, while all the y values contain the passed value. Data is returned as floats for the AffineTransform, although only the integer is meaningful.

Parameters:

y - the value to use for y in the x,y pairs

Returns:

a vector of x,y pairs ready for use in an AffineTransform
