cogpy.plot.hv.signals

Static-compatible HoloViews plot primitives for signal analysis.

All functions return static HoloViews elements (Curve, Image, Overlay, Layout, HoloMap) — never DynamicMap — so they work in both live notebooks and static HTML export.

Functions

drift_plot(matched_times, matched_lags[, ...])	Scatter plot of matched lags vs time, with optional polynomial fit.
event_histogram(values, *[, bins, xlabel, ...])	Histogram of scalar values (e.g. inter-event intervals, lags, amplitudes).
factor_loading_grid(loadings, *[, ...])	Grid of spatial loading maps, one per factor, at peak frequency.
lag_histogram(counts, bin_edges, *[, title, ...])	Plot a cross-correlogram from event_lag_histogram output.
psd_curve(psd, freqs, *[, label, logx, logy])	PSD as a HoloViews Curve.
psd_overlay(psds, *[, logx, logy, title])	Overlay multiple PSDs for comparison (e.g. before/after).
psd_with_lines(psd, freqs, line_freqs, *[, ...])	PSD curve with vertical lines marking detected spectral peaks.
signal_trace(signal, *[, time, label, ...])	Simple time-series trace as a HoloViews Curve.
signal_traces_overlay(signals, *[, title, ...])	Overlay multiple time-series traces (e.g. before/after comparison).
spatial_heatmap(data, *[, ap_dim, ml_dim, ...])	Static heatmap of a 2D (AP, ML) scalar field.
spatial_heatmap_grid(maps, *[, ap_dim, ...])	Grid layout of multiple spatial heatmaps (e.g. per-band power, per-metric).
triggered_waveform(template[, std, ...])	Plot a triggered average waveform with optional ±1 std band.
triggered_waveform_grid(templates[, stds, ...])	Grid of triggered waveforms laid out by (AP, ML) electrode position.
