Plot targets and forecast for backtest pipeline.

This function doesn’t support intersecting folds.

Parameters:

  • forecast_df (DataFrame) – forecasted dataframe with timeseries data

  • ts (TSDataset) – dataframe of timeseries that was used for backtest

  • segments (List[str] | None) – segments to plot

  • columns_num (int) – number of subplots columns

  • history_len (int | Literal['all']) – length of pre-backtest history to plot, if value is “all” then plot all the history

  • figsize (Tuple[int, int]) – size of the figure per subplot with one segment in inches

Raises:

  • ValueError: – if history_len is negative

  • ValueError: – if folds are intersecting
