seaborn.objects.Plot can't realize bivariate distribution

[moonlighthalfwindow]

fig = plt.figure()
ax = fig.add_subplot(111)
p = (
    so.Plot(tips, x='tip', color='sex')
    .add(so.Bar(alpha=1), so.Hist(), so.Stack())
    .label(color='')
    .on(ax)
    .plot(pyplot=True)
)
p.show()

The y parameter passed in when Hist is called has no effect, it will have no effect on the graphing, it will simply generate a y-axis label and cannot generate a bivariate distribution.
I'm looking forward to the implementation of this feature.
