Method Detail

generateTicks

public java.util.List<Tick> generateTicks(double min,
                                          double max,
                                          int maxTicks,
                                          boolean allowMinMaxOver,
                                          boolean tight)

Generate a list of ticks that span range given by min and max. The maximum number of ticks is exceed by one in the case where the range straddles zero.

Parameters:

min -

max -

maxTicks -

allowMinMaxOver - allow min/maximum overwrite

tight - if true then remove ticks outside range

Returns:

a list of the ticks for the axis

generateIndexBasedTicks

public java.util.List<Tick> generateIndexBasedTicks(double min,
                                                    double max,
                                                    int maxTicks,
                                                    boolean tight)

Generate a list of ticks that span range given by min and max.

Parameters:

min -

max -

maxTicks -

tight - if true then remove ticks outside range (ignored)

Returns:

a list of the ticks for the axis

generateLogTicks

public java.util.List<Tick> generateLogTicks(double min,
                                             double max,
                                             int maxTicks,
                                             boolean allowMinMaxOver,
                                             boolean tight)

Parameters:

min - (must be >0)

max - (must be >0)

maxTicks -

allowMinMaxOver - allow min/maximum overwrite

tight - if true then remove ticks outside range

Returns:

a list of the ticks for the axis
