TradingView Lightweight Charts for spaday.

Documentation

• Build a live chart — guided first chart.
• Update chart data and appearance — task-focused recipes.
• API reference — component props and package descriptor.
• Why a wrapper component? — integration design and tradeoffs.

Quick example

from spaday import serve
from spaday_lightweight_charts import LightweightChart

chart = LightweightChart(
    type="area",
    data=[{"time": "2026-01-01", "value": 42}],
)

serve(chart, packages=["lightweight-charts"])

data accepts a point array or a time-keyed mapping. Bind it to a spaday store field for live updates. Supported series types are line, area, candlestick, bar, and histogram.

Run the local example

python -m pip install -e ".[examples]"
python -m spaday_lightweight_charts.example

Open http://127.0.0.1:8011 to inspect the complete dashboard example: three responsive charts, server-streamed price data, renderer controls, per-point colors, and light/dark themes. It passes the local package descriptor directly, so it does not install or resolve the integration from GitHub.
