Method Detail

setPrecision

public void setPrecision(int precision)

set the precision of the output formatting

Specified by:

setPrecision in interface AxisPosFormatter

Parameters:

prec - the number of places right of the decimal point. Precision can have the following ranges:

    < -2   print default precision (2)
      -2   only the nearest hour should be printed.  
      -1   print value to the nearest minute.
       0   print value to the nearest second (with no decimal point).
    >= 1   print value with prec number of digits right of the
           decimal in the seconds field

public int getPrecision()

return the currently set precision

toString

public java.lang.String toString(double degrees,
                       int precision)

return a value as a string with a specified precision

Specified by:

toString in interface AxisPosFormatter

Parameters:

val - the input value

prec - the number of places right of the decimal point. Precision can have the following ranges:

    < 2   print with "natural" precision (whatever Java gives it)
