It's hard for me to provide feedback without seeing your code. Perhaps the original SO post could help: https://stackoverflow.com/q/35042255/3197404
My gist is quite old. Perhaps the new plotly library has exactly what you need: https://plotly.com/python/2d-histogram-contour/
Hi, thank you for sharing this solution! I am wondering how can we save the figure as a pdf file if using your function. When I tried to do fig.savefig('xxx.pdf'), I will lose the marginal distribution plots in the file. I think it is due to the fact that we removed some axes, making it very tricky. Would appreciate it if you can help to figure it out.

@YuHuang3019 a lot has changed in seaborne and I haven't used the pdf export myself.
As an alternative solution you could try Altair which is my current default plotting library:
https://iliatimofeev.github.io/altair-viz.github.io/gallery/scatter_marginal_hist.html
You can export Altair plots in different formats for downstream processing.

@dkapitan Hi Daniel, thank you so much for sharing this package with me. I just realized that I did plot out the marginal distributions but somehow the color and linewidth for the distributions are too light/small to show. I checked the pdf files on the browser before and I could not see the distribution plots. I later downloaded the file, zoomed in the pdf, and then I was able to figure this out. Sincerely thank you again for your quick response!
