Column Charts

Vertical column chart. Supports negative values and multiple series.

Basic usage:

from charted.charts.column import ColumnChart

chart = ColumnChart(data=[1, 2, 3], labels=["a", "b", "c"])
chart.html

With negative values (growth rates):

chart = ColumnChart(
    title="Year-over-Year Growth Rate (%) by Segment",
    data=[12, -8, 22, 18, -5, 30],
    labels=["Q1", "Q2", "Q3", "Q4", "Q5", "Q6"],
    width=700,
    height=500,
)

Multi-series (grouped columns, one per series):

chart = ColumnChart(
    title="Revenue vs Costs vs Net (%)",
    data=[
        [12, -8, 22, 18, -5, 30],    # Revenue
        [-3, -15, 5, -2, -20, 8],    # Costs
        [9, -23, 17, 16, -25, 38],   # Net
    ],
    labels=["Q1", "Q2", "Q3", "Q4", "Q5", "Q6"],
    width=700,
    height=500,
)

Adjust column width with column_gap (0–1, default 0.5):

chart = ColumnChart(data=[1, 2, 3], labels=["a", "b", "c"], column_gap=0.3)
