Code:
with heatmap:
heatmap_data = config.query(config.stock_heatmap_query)
heatmap_data[“return”] = heatmap_data[“return”] * 100
heatmap_data = heatmap_data.sort_values(by=“ticker”)

heatmap_plot = px.treemap(
    heatmap_data,
    path=[
        px.Constant("Stock Heatmap (Sigma Spike)"),
        "sector",
        "industry",
        "ticker",
    ],
    values="marketcap",
    color="sigmaspike",
    color_continuous_scale=[config.red] * 5
    + [config.darkgrey]
    + [config.green] * 5,
    color_continuous_midpoint=0,
)
