Method Detail

invertExtent

public final Array<Double> invertExtent(double y)

Returns the extent of values in the input domain [x0, x1] for the corresponding value in the output range y, representing the inverse mapping from range to domain.

This method is useful for interaction, say to determine the value in the input domain that corresponds to the pixel location under the mouse.

Parameters:

y - the output value to be converted to a domain range

Returns:

the array of doubles

invertExtent

public final Array<Double> invertExtent(String y)

Returns the extent of values in the input domain [x0, x1] for the corresponding value in the output range y, representing the inverse mapping from range to domain.

This method is useful for interaction, say to determine the value in the input domain that corresponds to the pixel location under the mouse.

Parameters:

y - the output value to be converted to a domain range

Returns:

the array of doubles
