org.das2.graph.TickVDescriptor

A TickVDescriptor describes the position that ticks should be drawn, so that a fairly generic tick drawing routine can be used for multiple types of axes.

TickVDescriptor( double[] minorTicks, double[] ticks, Units units )

creates a TickVDescriptor with the given minor and major ticks.

TickVDescriptor( QDataSet ticks )

create the tickVDescriptor for a bunch of given ticks. The first two ticks are used to derive minor ticks, using the DomainDivider code.

enclosingRange

enclosingRange( DatumRange dr, boolean minor ) → DatumRange

Defining method for getting the range close to the given range, but containing at least one minor(or major) tick interval.

Parameters

findTick

findTick( Datum xDatum, double direction, boolean minor ) → Datum

Locates the next or previous tick starting at xDatum.

Parameters

xDatum - find the tick closest to this.
direction - -1 previous, 1 next, 0 closest
minor - find closest minor tick, major if false.

Returns:

the closest tick. If there is no tick in the given direction, then the behavior is undefined.
