rename axes?

Does altair have redim-like or xlab/ylab-like functionality?

I know it’s possible to set axis titles via alt.Axis(title='NEW TITLE'), but I’m wondering if it’s possible to do this in an alternate way, say if the chart object has already been created, but one just wants to modify the axis labels. For example in ggplot:

p <- ggplot(df) +
    geom_point(aes(x, y))
p

# "curious plot, i wonder what it looks like with axis titles"
p +
    xlab("interesting axis 1") +
    ylab("interesting axis 2")

You could do something like this:

chart = alt.Chart(data).encode(
    alt.X('foo'),
    alt.Y('bar')
)

chart.encoding.x.title = 'new title'
chart.encoding.y.title = 'another new title'

Yes, for example:

chart = alt.Chart(data).encode(
    alt.X('foo', title='Foo', axis=alt.Axis(titleFont="Helvetica Neue"))
)
