Line Charts

Line chart. Supports multiple overlapping series, negative values, and custom x-axis positions.

Basic usage:

from charted.charts.line import LineChart

chart = LineChart(data=[1, 2, 3], labels=["a", "b", "c"])
chart.html  # returns SVG string

Multi-series (overlapping lines):

import math
n = 20
chart = LineChart(
    title="Signal Analysis: Raw vs Filtered vs Baseline",
    data=[
        [math.sin(i * 0.5) * 30 + (i % 7 - 3) * 5 for i in range(n)],  # Raw
        [math.sin(i * 0.5) * 25 for i in range(n)],                      # Filtered
        [math.sin(i * 0.5) * 10 - 5 for i in range(n)],                  # Baseline
    ],
    labels=[str(i) for i in range(n)],
    width=700,
    height=400,
)

XY mode with real x-values (temperature anomaly):

chart = LineChart(
    title="Temperature Anomaly vs Baseline (1990-2009)",
    data=[anomalies, [0] * 20],
    x_data=list(range(1990, 2010)),
    labels=[str(y) for y in range(1990, 2010)],
    width=700,
    height=400,
)
