PiecewiseITS.plot#

PiecewiseITS.plot(*, round_to=2, hdi_prob=0.94, figsize=(10, 10), show=True, legend_kwargs=None)[source]#

Plot the piecewise interrupted time-series results.

Parameters:

  • round_to (int | None) – Number of decimals used to round numerical results in the figure title. Defaults to 2. Use None to render raw numbers.

  • hdi_prob (float) – Probability mass of the highest density interval drawn around the fitted, counterfactual, causal effect, and cumulative effect bands. Must be in (0, 1]. Ignored for OLS models. Defaults to HDI_PROB (currently 0.94).

  • figsize (tuple[float, float]) – Width and height of the figure in inches, passed to matplotlib.pyplot.subplots(). Defaults to (10, 10).

  • show (bool) – Whether to automatically display the plot. Defaults to True.

  • legend_kwargs (dict[str, Any] | None) – Keyword arguments to adjust legend placement and styling. Supported keys: loc, bbox_to_anchor, fontsize, frameon, title (bbox_transform is accepted alongside bbox_to_anchor). The existing legend is modified in place so that custom handles are preserved.

Returns:

  • fig (matplotlib.figure.Figure) – The figure that was created.

  • ax (list[matplotlib.axes.Axes]) – The three axes (top: observed, fitted and counterfactual; middle: causal effect; bottom: cumulative effect).

Return type:

tuple[Figure, list[Axes]]
