Method Detail

getTerminator

protected Shape getTerminator(BigDecimal argument,
                              BigDecimal value,
                              BigDecimal xScalar,
                              BigDecimal yScalar)

Produces a terminator.

Parameters:

argument - the x-coordinate.

value - the y-coordinate.

xScalar - transforms horizontal graphical positions to x-coordinates.

yScalar - transforms vertical graphical positions to y-coordinates.

Returns:

a terminator on position (argument / xScalar, value / yScalar).
