ax.set_aspect('equal')

[jiajinbu]

Does seaborn object can make the scale of x and y equal, like ax.set_aspect('equal').

Same issue. I have tried use following scripts, but still not work.

fig = (
    so.Plot(penguins, x="bill_length_mm", y="bill_depth_mm")
    .add(so.Dot())
    .plot()._figure
)
fig.axes[0].set_aspect("equal")
fig

@liuzj039 why do you think that's not working? Looks right to me. Here's a pure matplotlib version:

f, ax = plt.subplots()
ax.scatter(x="bill_length_mm", y="bill_depth_mm", data=penguins)
ax.set_aspect("equal")

In any case, this functionality isn't exposed through the Plot interface yet, to answer the main question.

I seem to have misunderstood the meaning of aspect. The code below is fine.

fig = (
    so.Plot(penguins, x="bill_length_mm", y="bill_depth_mm")
    .add(so.Dot())
    .layout()
    .limit(x=(0,60), y=(0, 60))
    .plot()._figure
)
fig.axes[0].set_aspect("equal")
fig

Yes, aspect="equal" means that the same distance in data coordinates along the two axes will take up the same distance in physical coordinates. So you only get a square plot if the limits of the axes are identical.

Thank you very much for your detailed explanation
