Altair Grouped Bar Chart With Multiple Conditions

Question

I have this DataFrame called table:

    TERM                        Bitcoin       S&P500    Real Estate Gold
0   High-Inflation/ Short term  3097.94       -3700.78  761.23      6512.71
1   High-Inflation/ Mid term    —             -3080.01  -8434.66    3242.40
2   High-Inflation/ Long term   —             -2089.25  -9117.96    8174.43
3   Low-Inflation/ Short term   780200.00     -273.71   1824.72     2214.51
4   Low-Inflation/ Mid term     21013600.00   5331.40   35810.58    -2879.37
5   Low-Inflation/ Long term    978017143.00. 15045.41  35895.81    861.90

And I want to make a grouped (or stacked) bar chart that distinguishes return on investments for each of these assets based on the TERM column. I have tried this:

alt.Chart(table).transform_fold(
    ["Bitcoin", "S&P500", "Real Estate", "Gold"], as_=["key", "value"]
).mark_bar().encode(
        x="key:N",
        y="value:Q",
        color="key:N",
        column="TERM",
    )

But that doesn't work.
