Class BaseAxisRangeAbstract

Readonlycurrent

Readonlyoriginal

currentDistance

• get currentDistance(): number

  Returns the current distance between the start and end of the range.

  Returns number

originalDistance

• get originalDistance(): number

  Returns the original (e.g. before any zooming or panning) distance between the start and end of the range.

  Returns number

scaleFactor

• get scaleFactor(): number

  The ratio between the current and original distance.

  Returns number

AbstractconstrainedScale

• constrainedScale(
      factor: number,
      value: number,
      constraint: [min: number, max: number],
  ): BaseAxisRange

  Scales the axis-range by the specified scale factor, but constrains the range to the specified constraint min and max. The equations are written so that the zooming (scaling) occurs at the specified value, and expands/contracts equally from that value.

  Parameters

  • factor: number

    The scale factor

  • value: number

    The value at which the zoom is initiated

  • constraint: [min: number, max: number]

    The min and max range

  Returns BaseAxisRange

  A new continuous-axis range with updated values

matchesOriginal

• matchesOriginal(start: number, end: number): boolean

  Determines whether the specified (start, end) interval matches the original interval

  Parameters

  • start: number

    The start of the interval

  • end: number

    The end of the interval

  Returns boolean

  true if the specified interval matches the original interval; false otherwise

Abstractscale

• scale(factor: number, value: number): BaseAxisRange

  Scales the axis-range by the specified scale factor from the specified value. The equations are written so that the zooming (scaling) occurs at the specified value, and expands/contracts equally from that value.

  Parameters

  • factor: number

    The scale factor

  • value: number

    The time from which to scale the interval

  Returns BaseAxisRange

  A new continuous-axis range with updated values

Abstracttranslate

• translate(
      amount: number,
      constraints?: [start: number, end: number],
  ): BaseAxisRange

  Translates the axis-range by the specified amount

  Parameters

  • amount: number

    The amount by which to translate the axis-range

  • Optionalconstraints: [start: number, end: number]

    Optional constraint interval in which the axis range must be within

  Returns BaseAxisRange

  An updated ContinuousAxisRange that has been translated by the specified amount

Abstractupdate

• update(start: number, end: number): BaseAxisRange

  Updates the axis-range based on the new start and end values

  Parameters

  • start: number

    The new start of the axis-range

  • end: number

    The new end of the axis range

  Returns BaseAxisRange

  The updated axis-range type, with all other values unchanged

AbstractupdateOriginal

• updateOriginal(start: number, end: number): BaseAxisRange

  Updates the original range with the new start and end values.

  Parameters

  • start: number

    The new value for the start of the original range

  • end: number

    The new value for the end of the original range

  Returns BaseAxisRange

  The updated original range.
