Methods

buildHighlights(IDataSet<Entry> set, int dataSetIndex, double xVal, Rounding rounding) → List<Highlight>

An array of Highlight objects corresponding to the selected xValue and dataSetIndex.

inherited

getClosestHighlightByPixel(List<Highlight> closestValues, double x, double y, AxisDependency axis, double? minSelectionDistance) → Highlight?

Returns the Highlight of the DataSet that contains the closest value on the y-axis.

inherited

getClosestStackIndex(List<Range?> ranges, double? value) → int

Returns the index of the closest value inside the values array / ranges (stacked barchart) to the value given as a parameter.

getData() → BarLineScatterCandleBubbleData<IBarLineScatterCandleBubbleDataSet<Entry>>?

override

getDistance(double x1, double y1, double x2, double y2) → double

Calculates the distance between the two given points.

override

getHighlight(double x, double y) → Highlight?

override

getHighlightForX(double xVal, double x, double y) → Highlight?

Returns the corresponding Highlight for a given xVal and x- and y-touch position in pixels.

inherited

getHighlightPos(Highlight h) → double?

inherited

getHighlightsAtXValue(double xVal, double x, double y) → List<Highlight>

Returns a list of Highlight objects representing the entries closest to the given xVal. The returned list contains two objects per DataSet (closest rounding up, closest rounding down).

inherited

getMinimumDistance(List<Highlight> closestValues, double pos, AxisDependency axis) → double

Returns the minimum distance from a touch value (in pixels) to the closest value (in pixels) that is displayed in the chart.

inherited

getStackedHighlight(Highlight high, IBarDataSet set, double xVal, double yVal) → Highlight?

This method creates the Highlight object that also indicates which value of a stacked BarEntry has been selected.

getValsForTouch(double x, double y) → MPPointD

Returns a recyclable MPPointD instance. Returns the corresponding xPos for a given touch-position in pixels.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String
