Functions

abstract fun getBottomLayerMargin(context: CartesianMeasuringContext, verticalLabelPosition: Position.Vertical, maxLabelHeight: Float, maxLineThickness: Float): Float

Returns the bottom CartesianLayer-area margin required by the VerticalAxis.

abstract fun getHeightMeasurementLabelValues(context: CartesianMeasuringContext, position: Axis.Position.Vertical): List<Double>

Returns, as a list, the y values for which the VerticalAxis is to create labels and measure their heights during the measuring phase. The height of the tallest label is passed to other functions.

abstract fun getLabelValues(context: CartesianDrawingContext, axisHeight: Float, maxLabelHeight: Float, position: Axis.Position.Vertical): List<Double>

Returns, as a list, the y values for which labels are to be displayed.

open fun getLineValues(context: CartesianDrawingContext, axisHeight: Float, maxLabelHeight: Float, position: Axis.Position.Vertical): List<Double>?

Returns, as a list, the y values for which ticks and guidelines are to be displayed.

open fun getShiftTopLines(context: CartesianDrawingContext): Boolean

Returns a boolean indicating whether to shift the lines whose y values are equal to CartesianChartRanges.YRange.maxY, if such lines are present, such that they’re immediately above the CartesianLayer bounds. If a top HorizontalAxis is present, the shifted tick will then be aligned with the axis line, and the shifted guideline will be hidden.

abstract fun getTopLayerMargin(context: CartesianMeasuringContext, verticalLabelPosition: Position.Vertical, maxLabelHeight: Float, maxLineThickness: Float): Float

Returns the top CartesianLayer-area margin required by the VerticalAxis.

abstract fun getWidthMeasurementLabelValues(context: CartesianMeasuringContext, axisHeight: Float, maxLabelHeight: Float, position: Axis.Position.Vertical): List<Double>

Returns, as a list, the y values for which the VerticalAxis is to create labels and measure their widths during the measuring phase. This affects how much horizontal space the VerticalAxis requests.
