dtwPlot

dtw.dtwPlot(x, type='alignment', **kwargs)

Plotting of dynamic time warp results

Methods for plotting dynamic time warp alignment objects returned by [dtw()].

Details

dtwPlot displays alignment contained in dtw objects.

Various plotting styles are available, passing strings to the type argument (may be abbreviated):

  • alignment plots the warping curve in d;

  • twoway plots a point-by-point comparison, with matching lines; see [dtwPlotTwoWay()];

  • threeway vis-a-vis inspection of the timeseries and their warping curve; see [dtwPlotThreeWay()];

  • density displays the cumulative cost landscape with the warping path overimposed; see [dtwPlotDensity()]

Additional parameters are passed to the plotting functions: use with care.

Parameters:

  • x – dtw object, usually result of call to [dtw()]

  • d – dtw object, usually result of call to [dtw()]

  • xlab – label for the query axis

  • ylab – label for the reference axis

  • type – general style for the plot, see below

  • plot_type – type of line to be drawn, used as the type argument in the underlying plot call

  • ... – additional arguments, passed to plotting functions
