Diverging Bar Charts (templates)

Diverging bar charts are notoriously tricky to align in standard matplotlib. The templates module provides plot_diverging_bar — a pre-configured, highly styled template that handles text placement, axis centering, and cascading legend layout automatically.

import numpy as np

import dartwork_mpl as dm
from dartwork_mpl.templates import plot_diverging_bar

dm.style.use("report")

labels = [
    "Reliability",
    "Performance",
    "Usability",
    "Design",
    "Cost Efficiency",
]
negatives = np.array([-15, -30, -5, -45, -20])
positives = np.array([80, 60, 90, 45, 70])

fig, ax = plot_diverging_bar(
    labels=labels,
    neg_values=negatives,
    pos_values=positives,
    title="Customer Sentiment Analysis",
    neg_label="Negative feedback",
    pos_label="Positive feedback",
)
