6.2. Tomography widgets

Used for displaying or processing results [G1].

6.2.1. Displaying

A basic window capable of displaying a single reconstruction DiagGraphWindow. Can load a sequence of reconstructions and be synchronized with other windows.

Module with tkinter widgets for basic tomography analysis.

class tomotok.gui.widgets_tomo.DiagGraphWindow(parent=None, data=None, **kw)

Bases: tomotok.gui.widgets.GraphWindow

Based on GraphWindow class from widgets.py Used for displaying results of single diagnostic tomography

See documentation of GraphWindow for information about other keyword arguments.

Parameters:

parent : TKInter widget

Default is None. Used in GUI interface to specify hierarchy.

data : dict

Contains data, default is empty dict.

**kw

title : str {‘Bolometry’, ‘Neutrons’, ‘SXR’}

Name of graph window. If dname is not specified, title is used to determin what key from provided data to load.

dname : str {‘bol’, ‘ntr’, ‘sxr’}

Shorter string to specify diagnostic for graph window. Though not recommended, both title and dname can be used. If so, dname and title should always match to avoid inconsistency of title and data.
