AxisScaleType

EnumChartGuruChartGuru

public enum AxisScaleType

User-facing axis scale type. The single canonical control surfaced in every authoring UI (ChartGraphic Inspector, ChartDesignerWindow, ManualChartDataSource entry editor, UITK ChartGuruElement). Drives the legacy ChartGuru.AxisConfig.IsTimeAxis, ChartGuru.AxisConfig.IsBandAxis, and ChartGuru.AxisConfig.UseLogScale boolean accessors so existing API surfaces keep working.

Fields

Auto

Auto = 0

Infer the axis kind from the chart’s marks. Categorical when marks carry CategoryLabel values, otherwise numeric. Preserves historical auto-detection behaviour for charts that don’t explicitly opt into a scale type.

Returns

ChartGuru.AxisScaleType

Numeric

Numeric = 1

Linear numeric scale (default for numeric data).

Returns

ChartGuru.AxisScaleType

Categorical

Categorical = 2

Discrete band scale (one slot per category).

Returns

ChartGuru.AxisScaleType

Time

Time = 3

Time axis. Numeric values are interpreted as seconds since the Unix epoch.

Returns

ChartGuru.AxisScaleType

Logarithmic

Logarithmic = 4

Logarithmic scale (LogBase configurable on the axis).

Returns

ChartGuru.AxisScaleType

SymmetricLog

SymmetricLog = 5

Symmetric-log scale: linear within [-k, +k] (where k = ChartGuru.AxisConfig.LogScaleSlopeAtZero), logarithmic outside. Mirrors Swift Charts’ ScaleType.symmetricLog(slopeAtZero:).

Returns

ChartGuru.AxisScaleType

Power

Power = 6

Power scale: sign(v) * |v|^p where p = ChartGuru.AxisConfig.PowerExponent. Mirrors Swift Charts’ ScaleType.power(exponent:). ChartGuru.ScaleType.SquareRoot is routed through this case with p = 0.5.

Returns

ChartGuru.AxisScaleType
