Important

This package is archived and unmaintained (June 2026). It can no longer be instantiated (its [sources] entries point at paths that no longer exist) and has been superseded in the QPS lab by QPSConsole (live scan operation via QPSDrive's WebSocket server) and QPSLab (analysis GUI).

QPSView.jl

A real-time data visualization tool that automatically displays new data files added to a folder using GLMakie. The intended use case is experimental devices that save measurements to files, providing live plotting capabilities for immediate data inspection.

This program watches a folder using FileWatching and updates Observables for live data visualization. Features include:

• Live plotting with automatic updates when new files appear
• Start/stop monitoring controls
• Satellite panels for detailed data inspection
• File selection menus for viewing historical data
• Non-blocking operation (REPL remains available)

Quick Demo

# Load the demo
include("demo/demo.jl")

# Start live monitoring (non-blocking)
run_demo()

# Copy test files to see live updates
copy_test_file("sine")
copy_test_file("gauss")

# Or run automatic demo
run_auto_demo()

Basic Usage

using QPSView

# Start live plotting (async by default, REPL stays available)
task = live_plot("path/to/data/folder")

# For blocking behavior
live_plot("path/to/data/folder", async=false)

# With custom file type and loading function
live_plot("path/to/data", load_test_data, ".csv")
