MDA File Viz#

MDA File Visualization Module

Classes:

MDAFileVisualization: Main widget for displaying MDA file contents with tabbed interface MetadataSearchDialog: Dialog for searching within metadata text

Key Features:

  • Tabbed interface for Data, Plot, Metadata, and 2D visualization

  • Integrated 1D and 2D plotting with ChartView and ChartView2D

  • Interactive controls for curve fitting, styling, and log scales

  • Metadata search functionality

  • Dynamic tab visibility based on data dimensionality

  • Persistent UI state management

Dependencies:

  • PyQt6: GUI framework

  • mdaviz.chartview: 1D and 2D plotting widgets

  • mdaviz.data_table_view: Data table display

  • mdaviz.fit_models: Curve fitting functionality

  • mdaviz.utils: Utility functions for UI loading

Usage:

The MDAFileVisualization widget is typically instantiated as part of the main application window and receives MDA file data through: - setTableData(): Sets the data table content from MDA file - setMetadata(): Sets the metadata text content - setPlot(): Sets the 1D plotting widget (ChartView) with data from user selections - set2DData(): Sets 2D data for multi-dimensional arrays - update2DPlot(): Updates 2D plots based on user selections in 2D controls
