Typing of ApexAxisChartSeries

[davetapley]

The linked docs don't explicitly show it...

apexcharts.js/types/apexcharts.d.ts

Lines 300 to 307 in c6f544f

	* According to the documentation at
	* https://apexcharts.com/docs/series/
	* Section 1: data can be a list of single numbers
	* Sections 2.1 and 3.1: data can be a list of tuples of two numbers
	* Sections 2.2 and 3.2: data can be a list of objects where x is a string
	* and y is a number
	* And according to the demos, data can contain null.
	* https://apexcharts.com/javascript-chart-demos/line-charts/null-values/

Nor does the typing allow it...

apexcharts.js/types/apexcharts.d.ts

Lines 337 to 339 in c6f544f

	| [number, number | null][]
	| [number, (number | null)[]][]
	| number[][];

But passing data like this does work at runtime:

    "data": [
        [
            "2024-12-02T22:00:00Z",
            0.0
        ],
        [
            "2024-12-02T21:00:00Z",
            0.0
        ],

Despite failing type check (understandably) with:

Type '[string, number][]' is not assignable to type '(number | null)[] | { x: any; y: any; fill?: ApexFill | undefined; fillColor?: string | undefined; strokeColor?: string | undefined; meta?: any; goals?: any; barHeightOffset?: number | undefined; columnWidthOffset?: number | undefined; }[] | [...][] | [...][] | number[][]'.
  Type '[string, number][]' is not assignable to type '(number | null)[]'.
    Type '[string, number]' is not assignable to type 'number'.ts(2322)

Is this undocumented/untyped functionality which is but supported (i.e. a bug in the types), or an edge case which just happens to work at runtime?
