set_labels
set_labels(df, labels=None, *, set_panel=False)Declare human-readable variable labels on df and return it.
The labels are stored under df.attrs["geometrics_labels"] so that subsequent explore_* / analyze_* calls can title axes, legends and table headers with them. Explicit label= arguments to those functions still take precedence.
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| df | pd.DataFrame | The data frame (modified in place — its attrs are updated and the same object is returned). |
required |
| labels | Mapping[str, str] | pd.DataFrame | None | Either a {column_name: label} mapping, or a data-dictionary frame (df_dict) whose label / var_def columns supply the labels. None leaves the stored mapping unchanged. |
None |
| set_panel | bool | When True and labels is a df_dict, also declare the structural metadata it carries: the panel (entity / time, plus an entity_name column tagged role == "entity_name") via :func:~geometrics.set_panel, and the analytical roles (role of outcome / covariate) via :func:~geometrics.set_roles. |
False |
Returns
| Name | Type | Description |
|---|---|---|
| pandas.DataFrame | The same df, with df.attrs["geometrics_labels"] updated. |
Examples
Declare labels once, then explore with readable titles:
import pandas as pd
import geometrics as gm
df = pd.DataFrame({"region": ["A", "B"], "gini": [0.42, 0.35]})
df = gm.set_labels(df, {"gini": "Regional inequality (Gini)"})
