Method Detail

getTicks

TickRun getTicks(double dlo,
                 double dhi,
                 boolean withMinor,
                 Captioner captioner,
                 Orientation[] orients,
                 int npix,
                 double crowding)

Generates tick marks for labelling a plot axis.

The supplied list of orientations is attempted in order; if the required crowding can be satisfied by any of them, that orientation will be used. If it can't be supplied by any (because of unavoidable label overlap) a lower crowding value may be used.

Parameters:

dlo - minimum axis data value

dhi - maximum axis data value

withMinor - if true minor axes are included, if false only major (labelled) ones are

captioner - caption painter

orients - array of label orientations in order of preference, must contain at least one element

npix - number of pixels along the axis

crowding - 1 for normal tick density on the axis, lower for fewer labels, higher for more

Returns:

tick array along with orientation actually used
