Method Detail

getTickPositions

double[] getTickPositions(Axis1D axis)
Returns:
an array containing positions of tick marks in axis coordinates (transformed by any AxisUnitConverter).

getTickLabels

java.lang.String[] getTickLabels(Axis1D axis,
                                 double[] tickPositions)
Parameters:
tickPositions - the output from getTickPositions( ).
Returns:
an array of string labels for the tick marks provided by getTickPositions( ).

getMinorTickPositions

double[] getMinorTickPositions(double[] tickPositions)
Provides the positions of minor tick marks. How these are rendered differently from regular tick marks can vary, but they will usually be smaller and will not have labels. The positions of the major ticks are provided as input, since the minor tick positions are usually based on these. However, implementations of AxisLabelHandler are free to ignore this argument.

Returns:
an array containing positions of minor tick marks in axis coordinates (transformed by any AxisUnitConverter).

getAxisLabel

java.lang.String getAxisLabel(Axis1D axis)
Returns:
a text label describing the axis (the type of data displayed, the units, etc...)

setAxisLabel

void setAxisLabel(java.lang.String label)
Parameters:
label - provides a hint regarding what label information to display

getAxisUnitConverter

AxisUnitConverter getAxisUnitConverter()
Returns:
the current AxisUnitConverter (used to determine values returned by getTickPositions() and getTickLabels()

setAxisUnitConverter

void setAxisUnitConverter(AxisUnitConverter converter)
Parameters:
converter - sets a new AxisUnitConverter
