can you give me Nvidia revenue, net income, operating cash flow net investing cash flow (ignore financing cash flow), stock price, and US 10 year yield on 1 chart. Can yield from web.

Calling: load - tickers=["NVDA"], metrics=["total_revenue", "net_income", "operating_cashflow", "cashflow_from_investment"] DataFrame 236 OK nvda_financial_statements (25 rows)

I'll help you build this multi-metric chart for Nvidia. Let me break this into parts:

  1. Load Nvidia financials (revenue, net income, operating cash flow, investing cash flow)
  2. Load Nvidia stock price
  3. Get US 10-year yield from the web

Let me start with the data loading in parallel.

The columns exist but the chart tool still rejects them — likely the space in "NVDA Price" / "US 10Y Yield" / "TTM …" trips it. Let me strip all spaces and retry.

Reading back stored DataFrames is failing (CSV round-trip issue with multi-space column names). I'll skip the rename step and rename in-place in the previous compute output by rebuilding fresh.

Calling: show_chart - dataframe_id=240, x="date", series=["TTM_Revenue", "TTM_NetIncome", "TTM_OpCF", "TTM_InvCF", "NVDA_Price", "US10Y_Yield"], chart_type="line", title="NVDA: TTM Revenue, Net Income, Op/Inv Cash Flow, Stock Price & US 10Y Yield" Error: Unknown series column(s): TTM_Revenue, TTM_NetIncome, TTM_OpCF, TTM_InvCF, NVDA_Price, US10Y_Yield

Calling: show - dataframe_id=240, rows=12

Clean column names now. Let me chart and show.

Calling: compute - code="\ndf = df_240.copy()\ndf = df.rename(columns={\n 'NVDA_Price':'Price',\n 'US10Y_Yield':'Yield',\n 'TTM_Revenue':'Revenue',\n 'TTM_NetIncome':'NetIncome',\n 'TTM_OpCF':'OpCF',\n 'TTM_InvCF':'InvCF',\n})\nresult = df\nprint(result.columns.tolist())\n", dataframe_ids=[240], name="nvda_combined_v4" Error: Illegal quoting in line 1.

Strange — the show tool reads the columns fine (['date','NVDA_Price','US10Y_Yield','TTM_Revenue',...]) but show_chart rejects them. The chart tool may be confused by the _ in column names too. Let me try with simple one-word names.

Calling: compute - code="\ndf = df_240.copy()\ndf.columns = [c.replace('TTM_','').replace('NVDA_','N').replace('US10Y_','U') for c in df.columns]\nprint(df.columns.tolist())\nprint(df.tail(3))\n", dataframe_ids=[240], name="nvda_combined_v4" Error: Python error:

The compute tool can't read df_240 back due to a CSV quoting issue. The compute writes a CSV with quotes that it then can't re-parse. To get a chartable output, I have to do the renaming inside the same compute that builds the DataFrame so it's never re-loaded.
