Methods
-
createPainter(
) → SeriesPainter< Series> -
Is called whenever series is created to create its seriesPainter
as well.
override
-
createVirtualTick(
int epoch, double quote) → Tick -
Creates a virtual tick for crosshair display when cursor is outside data range.
Each series type should implement this to return the appropriate tick type.
inherited
-
didUpdate(
ChartData? oldData) → bool -
Will be called by the chart when it was updated.
inherited
-
fillEntriesFromInput(
covariant AbstractSingleIndicatorSeries oldSeries) → void -
Fills the entries that are about to be painted based on input and
oldSeriesinherited -
getCrosshairDetailsBoxHeight(
) → double -
Returns the height of the crosshair details box for this series type.
Each series type should implement this to return the appropriate height.
inherited
-
getCrosshairDotPainter(
ChartTheme theme) → CrosshairDotPainter -
Returns a CrosshairDotPainter for painting a dot at the crosshair position.
Each series type should implement this to return the appropriate dot painter.
inherited
-
getCrosshairHighlightPainter(
Tick crosshairTick, double quoteToY(double p1), double xCenter, int granularity, double xFromEpoch(int p1), ChartTheme theme) → CrosshairHighlightPainter -
Returns a CrosshairHighlightPainter for highlighting the element at the crosshair position.
Each series type should implement this to return the appropriate highlight painter.
inherited
-
getCrossHairInfo(
Tick crossHairTick, int pipSize, ChartTheme theme, CrosshairVariant crosshairVariant) → Widget -
Each sub-class should implement and return appropriate cross-hair text
based on its own requirements.
inherited
-
getEpochOf(
Tick t, int index) → int -
Gets the real epoch for the given
t.inherited -
getMaxEpoch(
) → int? -
Maximum epoch of this ChartData on the chart's X-Axis.
inherited
-
getMinEpoch(
) → int? -
Minimum epoch of this ChartData on the chart's X-Axis.
inherited
-
getVisibleEntries(
int startIndex, int endIndex) → VisibleEntries< Tick> -
Creates visible entries based on
startIndexandendIndex.inherited -
initialize(
) → void -
Initializes entries from the input.
inherited
-
initializeIndicator(
) → CachedIndicator< Tick> -
Initializes the
_resultIndicator. -
isOldDataAvailable(
covariant AbstractSingleIndicatorSeries? oldSeries) → bool -
Checks whether the old data of the series is available to use
inherited
-
maxValueOf(
Tick t) → double -
Maximum value in
t.inherited -
minValueOf(
Tick t) → double -
Minimum value in
t.inherited -

) → List< double> -
Gets min and max quotes after updating visibleEntries as an array with
two elements
min, max.inherited -
resetLastEntryAnimation(
) → void -
Use this to reset last tick in entries animation by setting
prevLastEntry to
null.inherited -
