Constructor Detail

MathAxisScale

public MathAxisScale(NormalizedMathRange range)

Constructs a new MathAxisScale with the specified mapping range.

Parameters:

range - the mapping range

Method Detail

mapMark

public double mapMark(int i)

Finds position on axis of scale's label with the specified index.

Parameters:

i - the label index

Returns:

label's position on axis

setDrawSubScale

protected void setDrawSubScale(boolean drawSubScale)

Sets if the sub-scale on the axis should be drawn

Parameters:

drawSubScale - True if to draw sub-scale

findNearestMark

public int findNearestMark(double d)

Gets the index of label nearest to the specified position on axis.

Parameters:

d - the position on axis; value in range [0,1]

Returns:

index of nearest label

getMarkCount

public int getMarkCount()

Gets a number of marks in the scale.

Returns:

number of marks

getLabelAt

public java.lang.String getLabelAt(int i)

Gets a label at the specified position.

Parameters:

i - the label index

Returns:

the label at the specified position

getLabelAt

public java.lang.String getLabelAt(int i,
                                   java.util.Locale locale)

Gets a scale's label at the specified position. The number format set by setNumberFormat method is used to format number. If number format isn't set then default number format for the specified locale is used.

Parameters:

i - the label index
