Function to produce a plot of LFP electrode spectrograms

NetPyNE Options:

sim (NetPyNE sim object) – The sim object from which to get data.

Default: None uses the current NetPyNE sim object

  • SpectData (dict, str) –

    The data necessary to plot the LFP spectrogram.

    Default: None uses analysis.prepareSpectrogram to produce SpectData using the current NetPyNE sim object.

    If a str it must represent a file path to previously saved data.

  • axis (matplotlib axis) –

    The axis to plot into, allowing overlaying of plots.

    Default: None produces a new figure and axis.

  • timeRange (list) –

    Time range to include in the raster: [min, max].

    Default: None uses the entire simulation

  • electrodes (list) –

    A list of the electrodes to plot from.

    Default: ['avg', 'all'] plots each electrode as well as their average

  • pop (str) –

    A population name to calculate PSD from.

    Default: None uses all populations.

  • NFFT (int (power of 2)) – Number of data points used in each block for the PSD and time-freq FFT. Default: 256

  • noverlap (int (<nperseg)) – Number of points of overlap between segments for PSD and time-freq. Default: 128

  • nperseg (int) – Length of each segment for time-freq. Default: 256

  • minFreq (float) – Minimum frequency shown in plot for PSD and time-freq. Default: 1

  • maxFreq (float) – Maximum frequency shown in plot for PSD and time-freq. Default: 100

  • stepFreq (float) – Step frequency. Default: 1

  • smooth (int) – Window size for smoothing LFP; no smoothing if 0 Default: 0

  • logy (bool) –

    Whether to use a log axis.

    Default: False

  • normSignal (bool) –

    Whether to normalize the LFP data.

    Default: False

  • normPSD (bool) –

    Whether to normalize the PSD data.

    Default: False

  • filtFreq (int or list) –

    Frequency for low-pass filter (int) or frequencies for bandpass filter in a list: [low, high]

    Default: None does not filter the data

  • filtOrder (int) –

    Order of the filter defined by filtFreq.

    Default: 3

  • detrend (bool) –

    Whether to detrend the data.

    Default: False

  • transformMethod (str) –

    The transformation method to use, either ‘morlet’ or ‘fft’.

    Default: 'morlet'

  • returnPlotter (bool) –

    Whether to return the figure or the NetPyNE MetaFig object.

    Default: False returns the figure.

Plot Options:
  • showFig (bool) – Whether to show the figure.

    Default: False

  • saveFig (bool) – Whether to save the figure.

    Default: False

  • overwrite (bool) – whether to overwrite existing figure files.

    Default: True overwrites the figure file

    Options: False adds a number to the file name to prevent overwriting

  • legendKwargs (dict) – a dict containing any or all legend kwargs. These include 'title', 'loc', 'fontsize', 'bbox_to_anchor', 'borderaxespad', and 'handlelength'.

  • rcParams (dict) – a dict containing any or all matplotlib rcParams. To see all options, execute import matplotlib; print(matplotlib.rcParams) in Python. Any options in this dict will be used for this current figure and then returned to their prior settings.

  • title (str) – the axis title

  • xlabel (str) – label for x-axis

  • ylabel (str) – label for y-axis


LFPSpectrogramPlot – By default, returns the figure. If returnPlotter is True, instead returns the NetPyNE MetaFig.

Return type:

matplotlib figure
