Is there a way to rotate the y-axis label and sit in the upper left corner?

Many news charts rotate the y-axis label so it can be read left to right and lift it to sit above the top of the axis. I’ve roughly recreated this in Altair, but longer axis titles generate this bug. Any idea how to fix it? I don’t see a text anchor setting in Vega-Lite I can use.

import altair as alt
from vega_datasets import data

source = data.iowa_electricity()

alt.Chart(source, title="Iowa's renewable energy boom").mark_line().encode(
    x=alt.X(
        "year:T",
        axis=alt.Axis(title="Year")
    ),
    y=alt.Y(
        "net_generation:Q",
        title="Net generation (in thousand megawatthours)",
    ),
    color=alt.Color(
        "source:N",
        legend=alt.Legend(title="Electricity source"),
    )
).configure_axisY(
    titleAngle=0,
    titleY=-10,
    titleX=-10,
)

I guess I can close the ticket now. I doubt anyone cares, but IMHO this should be the y-axis’s default title position. Commonplace in media. Much more legible.

Looks like there’s an axis setting now called titleAlign. If I put “left” in there it seems to work.

import altair as alt
from vega_datasets import data

source = data.iowa_electricity()

alt.Chart(source, title="Iowa's renewable energy boom").mark_line().encode(
    x=alt.X(
        "year:T",
        axis=alt.Axis(title="Year")
    ),
    y=alt.Y(
        "net_generation:Q",
        title="Net generation (in thousand megawatthours)",
    ),
    color=alt.Color(
        "source:N",
        legend=alt.Legend(title="Electricity source"),
    )
).configure_axisY(
    titleAngle=0,
    titleAlign="left",
    titleY=-10,
    titleX=-10,
)
