Detailed Description

ROOT-based canvas for interactive visualization of muSR data and fits.

PMusrCanvas provides comprehensive visualization capabilities for muSR data analysis:

Display Modes:

• Time-domain data with fitted theory curves
• Difference plots (data - theory)
• Fourier transforms (real, imaginary, power, phase)
• Phase-optimized real Fourier spectra
• Averaged data across multiple runs

Supported Fit Types:

• Single histogram fits
• Asymmetry fits (forward-backward, alpha-beta-LR)
• Beta-NMR asymmetry
• Non-muSR data (generic X-Y plots with errors)

Interactive Features:

• Menu-driven view switching (Data/Fourier/Difference/Average)
• Keyboard shortcuts for quick navigation
• Phase adjustment for Fourier transforms
• Data export to ASCII format
• Graphics export (EPS, PDF, PNG, etc.)
• Automatic timeout for batch processing

Canvas Layout: The canvas is divided into several pads:

• Title pad: Displays MSR file title
• Data/Theory pad: Main plotting area for histograms/graphs
• Parameter pad: Shows fitted parameter values
• Theory pad: Lists theory functions used in fit
• Info/Legend pad: Displays run information and legend

Integration:

• Reads MSR files via PMsrHandler
• Accesses fit results via PRunListCollection
• Uses ROOT's TCanvas and graphics primitives
• Supports both interactive and batch modes

Note

The preprocessor tag MAKECLING is used to hide complex Boost Spirit headers from rootcling during dictionary generation
