Methods

_cleanXNaN

(
  • xcoords
  • ycoords
)
private

Cleans invalid x-coordinates by calculating their value based on the corresponding y-coordinate, the previous valid x-coordinate with its corresponding y-coordinate and the next valid x-coordinate with its corresponding y-coordinate. If there is no previous or next valid x-coordinate, the value will not be altered.

Parameters:

  • xcoords Array

    An array of x-coordinate values

  • ycoords Array

    An arry of y-coordinate values

_cleanYNaN

(
  • xcoords
  • ycoords
)
private

Cleans invalid y-coordinates by calculating their value based on the corresponding x-coordinate, the previous valid y-coordinate with its corresponding x-coordinate and the next valid y-coordinate with its corresponding x-coordinate. If there is no previous or next valid y-coordinate, the value will not be altered.

Parameters:

  • xcoords Array

    An array of x-coordinate values

  • ycoords Array

    An arry of y-coordinate values

_getNextValidCoordValue

(
  • coords
  • index
)
private

Returns the next valid (numeric) value in an array if available.

Parameters:

  • coords Array

    Array of values

  • index Number

    The index in the array in which to begin searching.

Returns:

Number

_getPreviousValidCoordValue

(
  • coords
  • index
)
private

Returns the previous valid (numeric) value in an array if available.

Parameters:

  • coords Array

    Array of values

  • index Number

    The index in the array in which to begin searching.

Returns:

Number

_stackCoordinates
