arviz_plots.plot_pair_focus

arviz_plots.plot_pair_focus(dt, focus_var, focus_var_coords=None, var_names=None, filter_vars=None, group='posterior', coords=None, sample_dims=None, plot_collection=None, backend=None, labeller=None, aes_by_visuals=None, visuals=None, **pc_kwargs)

Plot a fixed variable against other variables in the dataset.

Parameters:

dtxarray.DataTree

Input data

focus_var: str or DataArray

Name of the variable or DataArray to be plotted against all other variables.

focus_var_coordsmapping, optional

Coordinates to use for the target variable.

var_names: str or list of str, optional

One or more variables to be plotted. Prefix the variables by ~ when you want to exclude them from the plot.

filter_vars: {None, “like”, “regex”}, default None

If None (default), interpret var_names as the real variables names. If “like”, interpret var_names as substrings of the real variables names. If “regex”, interpret var_names as regular expressions on the real variables names.

groupstr, default “posterior”

Group to use for plotting. Defaults to “posterior”.

coordsmapping, optional

Coordinates to use for plotting.

sample_dimsiterable, optional

Dimensions to reduce unless mapped to an aesthetic. Defaults to rcParams["data.sample_dims"]

plot_collectionPlotCollection, optional

backend{“matplotlib”, “bokeh”, “plotly”, “none”}, optional

Plotting backend to use. Defaults to rcParams["plot.backend"]

labellerlabeller, optional

aes_by_visualsmapping, optional

Mapping of visuals to aesthetics that should use their mapping in plot_collection when plotted. Valid keys are the same as for visuals. By default, there are no aesthetic mappings at all

visualsmapping of {strmapping or False}, optional

Valid keys are:

• scatter -> passed to scatter_x

• divergence -> passed to scatter_xy. Defaults to False.

• xlabel -> labelled_x

• ylabel -> labelled_y

**pc_kwargs

Passed to arviz_plots.PlotCollection.wrap

Returns:

PlotCollection
