Enum-like object for implementations of default Formatting functions.

Type declaration

  • LogarithmicExponents: ((value: number, range: FormattingRange, locale?: string, logBase?: number | "e") => string)
      • (value: number, range: FormattingRange, locale?: string, logBase?: number | "e"): string

      • Formats number like "2×10¹⁰"

        Alternate, built-in formatting for logarithmic ticks. Better suited especially for applications with zooming.

         // Example, enable extreme ticks with exponent formatting
         chart
             .getDefaultAxisX()
             .setTickStrategy(AxisTickStrategies.Numeric, (ticks) =>
                 ticks
                     .setMajorFormattingFunction(FormattingFunctions.LogarithmicExponentsRounded)
                     .setMinorFormattingFunction(FormattingFunctions.LogarithmicExponents)
             )

        Parameters

        • value: number
        • range: FormattingRange
        • Optional locale: string
        • logBase: number | "e" = 10

        Returns string

  • LogarithmicExponentsRounded: ((value: number, range: FormattingRange, locale?: string, logBase?: number | "e") => string)
      • (value: number, range: FormattingRange, locale?: string, logBase?: number | "e"): string

      • Formats number like "10¹⁰"

        Alternate, built-in formatting for logarithmic ticks. Better suited especially for applications with zooming.

         // Example, enable extreme ticks with exponent formatting
         chart
             .getDefaultAxisX()
             .setTickStrategy(AxisTickStrategies.Numeric, (ticks) =>
                 ticks
                     .setMajorFormattingFunction(FormattingFunctions.LogarithmicExponentsRounded)
                     .setMinorFormattingFunction(FormattingFunctions.LogarithmicExponents)
             )

        Parameters

        • value: number
        • range: FormattingRange
        • Optional locale: string
        • logBase: number | "e" = 10

        Returns string

  • LogarithmicExtreme: ((value: number, range: FormattingRange, locale?: string, logBase?: number | "e") => string)
      • (value: number, range: FormattingRange, locale?: string, logBase?: number | "e"): string
      • Beta

        Formats number like "2.13×10¹⁰"

        Recommended to be used together with "extreme ticks" when logarithmic ticks are paired with requirement of zooming far in.

         // Example, enable extreme ticks with special formatting
         chart
             .getDefaultAxisX()
             .setTickStrategy(AxisTickStrategies.Numeric, (ticks) =>
                 ticks
                     .setExtremeTickStyle(chart.getTheme().xAxisNumericTicks.majorTickStyle)
                     .setExtremeFormattingFunction(FormattingFunctions.LogarithmicExtreme),
             )

        Parameters

        • value: number
        • range: FormattingRange
        • Optional locale: string
        • logBase: number | "e" = 10

        Returns string

  • LogarithmicNoExponents: ((value: number, range: FormattingRange, locale?: string, logBase?: number | "e") => string)
      • (value: number, range: FormattingRange, locale?: string, logBase?: number | "e"): string
      • Beta

        Default formatting function for logarithmic axis. Formats values like "0.1", "1", "10" and so on.

        Parameters

        Returns string

  • Numeric: ((value: number, range: FormattingRange) => string)
      • (value: number, range: FormattingRange): string

      • Formats a number.

        Returns

        Value formated as string

        Parameters
