Package: visualization

Visualization nodes.

These nodes generally open new plotting windows and display the data that is received by the node. Most of these nodes are meant for real-time visualization and will accept time series with a time and space axis, althouggh some nodes are suitable for offline data (e.g., TimeSeriesDiff and ScrollPlot).

Nodes in this package:

  • Bar Plot
    Plot streaming data in a realtime bar chart.

  • Connectivity Plot
    Plot estimated connectivity / directed or undirected information flow between 3d regions of interest (ROIs) in brain source space.

  • Cortex Activity Plot
    Plot estimated brain source activity on a 3d model of a brain in real time.

  • Head Activity Plot
    Plot EEG channel activity on a 3d model of a head in real time.

  • Image Plot Viewer
    Plot streaming 2D data as a live image (heatmap) in real time.

  • Inspect Packet
    Shows the contents of a Packet, including data tensor values, axes, streams, and markers.

  • Marker Stream Window
    Create a basic text window to display markers and times as they come in.

  • Marker Table Plot
    Display event markers and their timestamps in a real-time table.

  • Plot Dashboard
    Display multiple plots side by side in a single Qt window.

  • Scrolling Plot (Offline)
    Plot a multi-channel continuous time series in a scrollable plot offline.

  • Spectrum Plot
    Plot a multi-channel spectrum in real time.

  • Table Plot
    Display data values in a real-time table.

  • Time Series Diff
    Show the difference between two time series.

  • Time Series Plot
    Plot a multi-channel continuous streaming time series in real time.

  • Time Series Sweep Plot
    Plot a multi-channel continuous time series.

  • TopoPlot (Viewer)
    Plot EEG channels (electrodes) or NIRS channels (sources and detectors as discs, source-detector channels as lines) on a head outline, with colors based on the values in the incoming data.
