viz.theme_forest()

A minimal plotnine theme for forest plots.

Usage

Source

viz.theme_forest()

Returns a composable plotnine theme object suitable for forest plots of hazard ratios or other contrasts. Horizontal grid lines are suppressed. The y-axis line is removed so the term labels stand alone.

Returns

plotnine.theme

A composable theme object. Add it to a ggplot with +.

Examples

Apply the forest theme to a forest plot of Cox model hazard ratios:

import greenwood as gw

# Load data and fit a Cox model with two covariates
lung = gw.load_dataset("lung", backend="polars")
y = gw.Surv.right(lung["time"], event=(lung["status"] == 2))
cox = gw.CoxPH().fit(y, lung[["age", "sex"]])

# Draw a forest plot and apply the minimal forest theme
gw.plot_forest(cox, backend="plotnine") + gw.theme_forest()
