Functions and constants

get · iOS 16.0+

startIndex

TypeScript

get startIndex(): number

Swift declaration

var startIndex: Int { get }

The position of the first element in a nonempty collection. If the collection is empty, `startIndex` is equal to `endIndex`.

init · iOS 16.0+

init

TypeScript

static initThresholds(thresholds: Array<number>): NumberBins<number>

Swift declaration

nonisolated init(thresholds: [Value])

Creates N-1 bins with the given N `thresholds`. - Parameter thresholds: The threshold values that surround the bins. - Returns: The bins.

Swift declaration

var thresholds: [Value] { get }

Find the bin thresholds. - Returns: The bin thresholds that surround the bins.

Swift declaration

nonisolated init(data: [Value], desiredCount: Int? = nil, minimumStride: Value = 0) where Value : BinaryFloatingPoint

Automatically determine the bins from data. - Parameter data: The given data values. - Parameter desiredCount: The desired number of bins for the given data. If `nil`, infer the number of bins automatically from data using [Scott's normal reference rule](https://doi.org/10.1093/biomet/66.3.605) capped at 200. - Parameter minimumStride: The minimum allowed bin size. - Returns: The inferred bins.

TypeScript

indexAfter(i: number): number

Swift declaration

func index(after i: Int) -> Int

Returns the position immediately after the given index. The successor of an index must be well defined. For an index `i` into a collection `c`, calling `c.index(after: i)` returns the same index every time. - Parameter i: A valid index of the collection. `i` must be less than `endIndex`. - Returns: The index value immediately after `i`.

init · iOS 16.0+

init

TypeScript

static initRangeCount(range: SDKHandle, count: number): NumberBins<number>

Swift declaration

nonisolated init(range: ClosedRange<Value>, count: Int) where Value : BinaryFloatingPoint

Creates the given number of bins for the range. - Parameter range: The range of the bins. The first bin starts at the lower bound of the range, and the last bin ends at the upper bound of the range. - Parameter count: The exact number of bins.

init · iOS 16.0+

init

TypeScript

static initRangeCount20397(range: SDKHandle, count: number): NumberBins<number>

Swift declaration

nonisolated init(range: ClosedRange<Value>, count: Int) where Value : BinaryInteger

Creates the given number of bins for the range. Expects that the range length is a multiple of `count` to allow uniform integer bins. - Parameter range: The range of the bins. The first bin starts at the lower bound of the range, and the last bin ends at the upper bound of the range. - Parameter count: The exact number of bins.

get · iOS 16.0+

endIndex

TypeScript

get endIndex(): number

Swift declaration

var endIndex: Int { get }

The collection's "past the end" position---that is, the position one greater than the last valid subscript argument. When you need a range that includes the last element of a collection, use the half-open range operator (`..<`) with `endIndex`. The `..<` operator creates a range that doesn't include the upper bound, so it's always safe to use with `endIndex`. For example: let numbers = [10, 20, 30, 40, 50] if let index = numbers.firstIndex(of: 30) { print(numbers[index ..< numbers.endIndex]) } // Prints "[30, 40, 50]" If the collection is empty, `endIndex` is equal to `startIndex`.

subscript · iOS 16.0+

subscript

TypeScript

subscript(position: number): ChartBinRange<number>

Swift declaration

subscript(position: Int) -> ChartBinRange<Value> { get }

Accesses the element at the specified position. The following example accesses an element of an array through its subscript to print its value: var streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"] print(streets[1]) // Prints "Bryant" You can subscript a collection with any valid index other than the collection's end index. The end index refers to the position one past the last element of a collection, so it doesn't correspond with an element. - Parameter position: The position of the element to access. `position` must be a valid index of the collection that is not equal to the `endIndex` property. - Complexity: O(1)
