    Parameters

    Returns boolean

addEntryOrdered

  • addEntryOrdered(e: Entry): any

  • Adds an Entry to the DataSet dynamically. Entries are added to their appropriate index in the values array respective to their x-position. This will also recalculate the current minimum and maximum values of the DataSet and the value-sum.

    Returns any

applyFiltering

  • applyFiltering(scaleX: number): any

  • Parameters

    • scaleX: number

    Returns any
