class DISPLIB::TFplot

Time-frequency spectrogram QWidget rendering an Eigen matrix as a colour image.

Two constructors accept either a full or a frequency-cropped MatrixXd spectrogram together with a sample rate and a ColorMaps enum entry; calc_plot() builds the cached QImage that subsequent paintEvents draw.

TFplot(tf_matrix, sample_rate, lower_frq, upper_frq, cmap)​

Constructs TFplot class.

Parameters:

  • tf_matrix : Eigen::MatrixXd given spectrogram.

  • sample_rate : qreal given sample rate of signal related to th spectrogram.

  • lower_frq : qreal lower bound frequency, that should be plotted.

  • upper_frq : qreal upper bound frequency, that should be plotted.

  • cmap : ColorMaps colormap used to plot the spectrogram.

TFplot(tf_matrix, sample_rate, cmap)​

Constructs TFplot class.

Parameters:

  • tf_matrix : Eigen::MatrixXd given spectrogram.

  • sample_rate : qreal given sample rate of signal related to th spectrogram.

  • cmap : ColorMaps colormap used to plot the spectrogram.
