environmentaltools.graphics.bivariate_ensemble_pdf(df_sim: DataFrame, df_obs: dict, varp: list, file_name: str = None)[source]

Plot ensemble of bivariate PDFs comparing simulation with multiple observations.

Displays a grid of contour plots showing the bivariate probability density function for a simulation and multiple observational datasets.

Parameters:

  • df_sim (pd.DataFrame) – Simulated time series data.

  • df_obs (dict) – Dictionary where each key contains an observed time series DataFrame. Each will be plotted in a separate subplot.

  • varp (list) – List of two variable names [var1, var2] to plot.

  • file_name (str, optional) – File path to save the plot. If None, displays interactively. Defaults to None.

Returns:

Array of axes with the plots.

Return type:

matplotlib.axes.Axes

Note

Creates 3x3 grid with simulation in first subplot and observations following.
