Scatter3d + histogram2dcontour along z-axis

Hi everyone,

I have a 3D point cloud. I would love to plot the point cloud as 3D scatter and then at few z slices add in the contours lines from the histogram2dcontour. Iā€™m not able to get the histobram2dcontours into the 3D scatter plot at the specific z-slice and I could not find any examples of how to do it. Anyone know how to do it or know similar examples you could point me towards?
