grapa.datatypes.curveMath.CurveMath

class grapa.datatypes.curveMath.CurveMath(data, attributes, silent=False)

Bases: Curve

Class handling mathematical operations, to make them available to the GUI. The operations are readily accessible from command line, for example curve1 + curve2 - 20

__init__(data, attributes, silent=False)

Methods

`__init__`(data, attributes[, silent])
`add`(cst, curves[, graph, operator])	Add a constant or a (list of) curves to this curve.
`assemble_curve_xy`(idx_x, xory_x, idx_y, ...)	Assemble new Curve from data series of same length available in a Graph object.
`classNameGUI`()	Provide base data, for the GUI to show what subclass of curve this is.
`funcListGUI`(**kwargs)	Fills in the Curve actions specific to the Curve type. Retuns a list, which elements are instances of FuncGUI, or (old style): ::.
`inv`()	Return the inverse of this curve, i.e. 1 / Curve.
`neg`()	Return the negative of this curve, i.e. 0 - Curve.
`print_help`()	Prints help for the Curve subclass, generated from docstrings.
`swap_xy`()	Return a copy of this curve with x and y data swapped.

Attributes

CURVE

add(cst, curves, graph: Graph = None, operator='add'): Add a constant or a (list of) curves to this curve.

assemble_curve_xy(idx_x: int, xory_x: str, idx_y: int, xory_y: str, graph: Graph)

Assemble new Curve from data series of same length available in a Graph object.

Parameters:

idx_x – index of Curve in Graph, from which to pick the x data series
xory_x – is the x or y data series picked
idx_y – index of Curve in Graph, from which to pick the y data series
xory_y – is the x or y data series picked
graph – Graph object to work on

Returns:

a Curve with x and y data according to wishes

classmethod classNameGUI(): Provide base data, for the GUI to show what subclass of curve this is. Can be overridden, see CurveArrhenius.

funcListGUI(**kwargs)

Fills in the Curve actions specific to the Curve type. Retuns a list, which elements are instances of FuncGUI, or (old style):

[func,
 'Button text',
 ['label 1', 'label 2', ...],
 ['value 1', 'value 2', ...],
 {'hiddenvar1': 'value1', ...}, (optional)
 [dictFieldAttributes, {}, ...]] (optional)

By default, returns quick modifs for offset and muloffset (if already set), and a help for some plot types (errorbar, scatter).

Parameters:: kwargs – this function should be called specifying kwargs[‘graph’] the graph self is embedded in, and kwargs[‘graph_i’] as position of self in graph.

inv(): Return the inverse of this curve, i.e. 1 / Curve.

neg(): Return the negative of this curve, i.e. 0 - Curve.

print_help(): Prints help for the Curve subclass, generated from docstrings.

swap_xy(): Return a copy of this curve with x and y data swapped.
