2D Kde not show a contour far from the 3sigma one

[jecampagne]

Hello
Looking at KDE 2D example demo

I wander how to not display the very non-smooth contour located far from the 3-sigma contour.

Thanks

I am almost sure we did not show that contour. So probably something changed in matplotlib... Anyway, in the meantime a quick trick is to make the contour transparent with contour_kwargs={"alpha":0}

The fact that it doesn't happen in <=0.17.1 seems to point to that: https://python.arviz.org/en/v0.17.1/examples/plot_kde_2d_hdi.html. We'll have to look at what has changed, especially when providing hdi_probs, only the requested contour lines should be plotted
