Error: No data to plot.

Error message

Error: No data to plot.

What it means

The fixed-income rate-curve chart builds its DataFrame from an injected DataFrame, a list/Data payload, or by dumping obbject_item records; if the resulting frame is empty, it raises ValueError('Error: No data to plot.'). An empty frame means every input path yielded zero rows — the provider returned no curve data for the requested parameters.

Solutions

1. Inspect the raw response: res.to_df() — if empty, change provider/date/country.
2. Use a supported date (business day) and a provider covering the requested market (e.g. provider='fred' for US).
3. Ensure any injected data list is non-empty.

Example fix

# before
fig = obb.fixedincome.government.curve(date='2026-08-09', provider='fmp').charting.to_chart()  # Sunday

# after
fig = obb.fixedincome.government.curve(date='2026-08-07', provider='fmp').charting.to_chart()

df = res.to_df() if hasattr(res, 'to_df') else DataFrame([d.model_dump() for d in data])
assert not df.empty, 'curve request returned no rows; adjust date/country/provider'

def is_nonempty_frame(df) -> bool:
    """True when the converted curve frame has at least one row."""
    return df is not None and not df.empty

try:
    fig = views.fixedincome_curve(**kwargs)
except ValueError as e:
    if str(e) == 'Error: No data to plot.':
        kwargs['date'] = previous_business_day(kwargs['date'])
        fig = views.fixedincome_curve(**kwargs)
    else:
        raise

When it happens

Trigger: Calling obb.fixedincome.government.curve(...).charting.to_chart() (fixedincome_views.py:44) for a date/country combination with no yield curve data; passing an empty list as data; provider error upstream swallowed into empty results.

Common situations: Requesting curves for unsupported countries or maturities, dates on weekends/holidays with no snapshot, or free-tier providers with limited history.
