StarkMap.plotLevelDiagram(units='cm', highlightState=True, progressOutput=False, debugOutput=False, highlightColour='red', addToExistingPlot=False)[source]#

Makes a plot of a stark map of energy levels

To save this plot, see savePlot. To print this plot see showPlot. Pointers (handles) towards matplotlib figure and axis used are saved in fig and ax variables respectively.

Parameters
• units (char,optional) – possible values {’cm’,’GHz’,’eV’}; [case insensitive] if the string contains ‘cm’ (default) Stark diagram will be plotted in energy units cm $${}^{-1}$$; if value is ‘GHz’, Stark diagram will be plotted as energy $$/h$$ in units of GHz; if the value is ‘eV’, Stark diagram will be plotted as energy in units eV.

• highlightState (bool, optional) – False by default. If True, scatter plot colour map will map in red amount of original state for the given eigenState

• progressOutput (bool, optional) – if True prints the progress of calculation; Set to False by default.

• debugOutput (bool, optional) – if True prints additional information usefull for debuging. Set to False by default.

• addToExistingPlot (bool, optional) – if True adds points to existing old plot. Note that then interactive plotting doesn’t work. False by default.
