Working with KstScript

Class: Curve

Represents a curve formed from an X and a Y vector.

Inherits: DataObject

Collection class: CurveCollection

Constructors:

  • Curve ( x, y [, xError [, yError [, xMinusError [, yMinusError]]]] )

  • Curve ( hs )

Methods:

Properties:

Curve ( Vector x, Vector y [, Vector xError [, Vector yError [, Vector xMinusError [, Vector yMinusError]]]] )

  • Vector x - The X vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object.

  • Vector y - The Y vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object.

  • Vector xError - The X error bar vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object. [OPTIONAL]

  • Vector yError - The Y error bar vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object. [OPTIONAL]

  • Vector xMinusError - The X minus error bar vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object. [OPTIONAL]

  • Vector yMinusError - The Y minus error bar vector for the curve. Can be specified as a string containing the tag name of an existing vector, or as a vector object. [OPTIONAL]

Main constructor for Curve class. Constructing a new curve automatically adds it to the data collection of Kst.

Curve ( Histogram hs )

  • Histogram hs - Creates a curve from a histogram.

Constructor for Curve class. Allows a curve to be simply created from a Histogram class.

Point point ( number index )

  • number index - The index of the point to retrieve the coordinates for. Starts at 0.

Retrieve the coordinates for a given point in the curve. Returns an invalid point if that index does not exist.

number xErrorPoint ( number index )

  • number index - The index of the point to retrieve the coordinates for. Starts at 0.

Retrieve the value for a given point in the X error bars. Returns an invalid point if that index does not exist.

number yErrorPoint ( number index )

  • number index - The index of the point to retrieve the coordinates for. Starts at 0.

Retrieve the value for a given point in the Y error bars. Returns an invalid point if that index does not exist.

number xMinusErrorPoint ( number index )

  • number index - The index of the point to retrieve the coordinates for. Starts at 0.

Retrieve the value for a given point in the X minus error bars. Returns an invalid point if that index does not exist.

number yMinusErrorPoint ( number index )

  • number index - The index of the point to retrieve the coordinates for. Starts at 0.

Retrieve the value for a given point in the Y minus error bars. Returns an invalid point if that index does not exist.

string color

The color of the curve. Stored in the form "#RRGGBB" as hex values. This property can also be set with English strings such as "blue".

Vector xVector

The X axis vector for the curve.

Vector yVector

The Y axis vector for the curve.

Vector xErrorVector

The X axis error vector for the curve.

Vector yErrorVector

The Y axis error vector for the curve.

Vector xMinusErrorVector

The X axis negative error vector for the curve.

Vector xMinusErrorVector

The X axis negative error vector for the curve.
