AtomNumber

AtomNumber#

class AtomNumber(becExp)#

Bases: BecAnalysis

AtomNumber compute and plot atom number components vs scan.

Integrates AD density over ROI/sub-ROIs to obtain raw counts and, when density fits are available, separates thermal/condensate contributions. Supports normalized sub-ROI fractions and 1D/2D visualizations.

Method Summary
static handlePropEvents(src, evnt)#

Handle graphics updates when display properties change.

Parameters:

  • src (meta.property) – Property metadata

  • evnt (event.EventData) – Event object carrying affected instance

initialize()#

Initialize plots, listeners, and internal data containers.

Sets up 1D or 2D plotting layouts, creates data storage arrays, configures plot properties, and establishes property listeners.
