struct ScaleTypeThe ways you can scale the domain or range of a plot. Use this type with the `type:` parameter of `.chartXScale` view modifiers to customize scale types.
static get squareRoot(): ScaleTypestatic var squareRoot: ScaleType { get }A number scale where each range value y can be expressed as a square root function of the domain value x, with `y = a * sqrt(x) + b`. This is equivalent to a power scale with exponent 0.5.
static symmetricLogSlopeAtZero(slopeAtZero: number): ScaleTypestatic func symmetricLog(slopeAtZero: Double) -> ScaleTypeA number scale where each range value y can be expressed as a symmetric log function of the domain value x, with `y = a * sign(x) * log(1 + |x * slopeAtZero|) + b`. - Parameter slopeAtZero: A positive constant that controls the slope of the symmetric log function at zero.
static get symmetricLog(): ScaleTypestatic var symmetricLog: ScaleType { get }A number scale where each range value y can be expressed as a symmetric log function of the domain value x, with `y = a * sign(x) * log(1 + |x * slopeAtZero|) + b`. The constant `slopeAtZero` defaults to 1. You can configure it with `symmetricLog(slopeAtZero:)`.
static get log(): ScaleTypestatic var log: ScaleType { get }A number scale where each range value y can be expressed as a logarithmic function of the domain value x, with `y = a * log(x) + b`.
static get date(): ScaleTypestatic var date: ScaleType { get }A date scale where each range value y can be expressed as a function of the domain value x's timestamp, with `y = a * x.timeIntervalSinceReferenceDate + b`.
static power(exponent: number): ScaleTypestatic func power(exponent: Double) -> ScaleTypeA number scale where each range value y can be expressed as a power function of the domain value x, with `y = a * pow(x, exponent) + b`. - Parameter exponent: The exponent of the power function.
static get linear(): ScaleTypestatic var linear: ScaleType { get }A number scale where each range value y can be expressed as a linear function of the domain value x, with `y = a * x + b`.
static get category(): ScaleTypestatic var category: ScaleType { get }A scale that has discrete domain values as inputs.
