Error: No data to plot.

Error message

Error: No data to plot.

What it means

Raised by the derivatives futures curve charting view (derivatives_futures_curve) when, after normalizing the input - either a passed DataFrame, a list of Data models, or the OBBject item's dumped results - the resulting DataFrame is empty. The chart cannot be built from nothing, so it aborts before touching plotly.

Solutions

1. Verify the underlying fetch returns rows before enabling chart=True: inspect data.results length.
2. Check the symbol and date parameters are valid for the provider (e.g. obb.derivatives.futures.curve(symbol='VX', provider='cboe')).
3. If passing data= explicitly, confirm the DataFrame is non-empty and has expiration/price columns.
4. Retry during market hours or with another provider if the response was genuinely empty.

Example fix

# before
res = obb.derivatives.futures.curve(symbol='BADSYM', date='1990-01-01', provider='cboe', chart=True)

# after
res = obb.derivatives.futures.curve(symbol='VX', provider='cboe', chart=True)
assert res.results, 'no curve rows returned'

res = obb.derivatives.futures.curve(symbol=sym, provider=prov)
if not res.results:
    raise ValueError(f'no curve rows for {sym}; check symbol/date/provider')

try:
    data.show()  # or charting.to_chart()
except OpenBBError as e:
    if 'No data to plot' in str(e):
        logging.warning('curve fetch empty for %s', symbol)

When it happens

Trigger: Calling obb.derivatives.futures.curve(..., chart=True) when the fetcher returned zero rows (empty symbol/date), or passing data=[] / an empty DataFrame via chart_params; also when data is a list whose model_dump calls yield no columns.

Common situations: Delisted/unknown futures symbol; requesting a date with no curve data; provider outage returning an empty result; charting an OBBject whose results were already consumed/emptied.
