Constructor Detail

NumericYTickLocator

public NumericYTickLocator(double max,
                           double min,
                           int numTicsDesired,
                           int maxTics)

Pass-through constructor to constructs a numeric tick locator based on maximum and minimum values.

Parameters:

max - the largest value to be plotted

min - the smallest value to be plotted

numTicsDesired - the approximate desired number of tick marks

maxTics - the most allowed ticks

NumericYTickLocator

public NumericYTickLocator(double max,
                           double min,
                           int numTicsDesired,
                           int maxTics,
                           boolean force_simple)

Pass-through constructor to constructs a numeric tick locator based on maximum and minimum values. Allows one to specify using a simple locator, spacing ticks equally between max and min values.

Parameters:

max - the largest value to be plotted

min - the smallest value to be plotted

numTicsDesired - the approximate desired number of tick marks

maxTics - the most allowed ticks

force_simple - true to force the locator to create exactly numTicsDesired starting with min and ending with max

Method Detail

getTickMarkLocationsAsPairs

public double[] getTickMarkLocationsAsPairs(double x)

Returns an array of x,y pairs. The y value contains a y tick location, while all the x values contain the passed value.

Parameters:

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

Returns:

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