class: DateAxis

[21:7] extends: Axis

DateAxis wraps extfx.scene.chart.DateAxis (Christian Schudt's MIT-licensed date axis, vendored under src/extfx), a time axis for JavaFX XY charts that plots real dates instead of category label strings. It automatically chooses the tick granularity, from decades down to milliseconds, and a matching label format based on the visible range and the axis width, so a time series does not need pre-formatted string categories. Bounds are Aussom Date objects, the same type DatePicker uses: setters accept an Aussom Date and getters return an Aussom Date. Extends Axis, so all the shared axis methods (setLabel, setAnimated, setAutoRanging, tick styling, and so on) are inherited.

Methods

DateAxis (Lower = null, Upper = null)

Creates a DateAxis. With no bounds the axis auto-ranges to its data. When both bounds are given, the axis is fixed to that date range.
- @p Lower is an optional lower-bound Aussom Date.
- @p Upper is an optional upper-bound Aussom Date.
toJavaDate (DateObj)
fromJavaDate (D)
setLowerBound (DateObj)

Sets the axis lower bound, the earliest date shown.
- @p DateObj is an Aussom Date, or null to auto-range.
- @r this object for chaining
getLowerBound ()

Returns the axis lower bound as an Aussom Date, or null when unset.
- @r An Aussom Date, or null.
lowerBoundProperty ()

Returns the lowerBound ObjectProperty for binding.
- @r An AJO around the bound date ObjectProperty (for binding only).
setUpperBound (DateObj)

Sets the axis upper bound, the latest date shown.
- @p DateObj is an Aussom Date, or null to auto-range.
- @r this object for chaining
getUpperBound ()

Returns the axis upper bound as an Aussom Date, or null when unset.
- @r An Aussom Date, or null.
upperBoundProperty ()

Returns the upperBound ObjectProperty for binding.
- @r An AJO around the bound date ObjectProperty (for binding only).
setDateFormat (string Pattern)

Sets the tick label format from a date-format pattern, for example "yyyy-MM-dd" or "HH:mm". This replaces the automatic per-granularity formatting with a single fixed pattern.
- @p Pattern is a java.text.SimpleDateFormat pattern string.
- @r this object for chaining
setTickLabelFormatter (Converter)

Sets the tick label formatter directly.
- @p Converter is a javafx.util.StringConverter for Date (or FxObj).
- @r this object for chaining
getTickLabelFormatter ()

Returns the tick label formatter.
- @r An AJO around the StringConverter, or null.
tickLabelFormatterProperty ()

Returns the tickLabelFormatter ObjectProperty for binding.
- @r An AJO around the ObjectProperty.
