Depth layer in Azure Maps

Greetings!

 

I have absolutely no idea if this is the right place to ask this question but here goes anyway...

 

I'm looking for a layer that helps me visualize earthquakes not only by magnitude but also by depth.

 

I created this sample some few years ago using Power BI - It's not in English but you'll probably get the drill.
(see here: https://app.powerbi.com/view?r=eyJrIjoiNjliYjgxZDMtODc0ZC00MTEyLWE1NGUtZWRlNzcwODM2M2FjIiwidCI6IjQwMjY1ZWI5LTY3ZTQtNGYxYi1iMDMyLTEzNGM5NjY1MWYwNSIsImMiOjh9 ) 

I'm using MapBox here but I'd like to see what is possible for the ever growing Azure Map which is a visual within the visualization family of Power BI

Now using only Azure Maps in Power BI the closest I've got to showing the depth is using bar charts instead of bubbles but the problem is obviously that that the bars go up when they really should go down. Adding negative values just stops at zero so no point changing the values.




I'm now looking for some kind of a layer that I can use and map the depth values accordingly but I'm totally lost on how to do that and of course I'm also missing the magnitude measure so this really is a question of a 3D rendered visual that takes into account the magnitude of the earthquake and also depth by latitude and longitude.

I've looked at Mapbox and Arcgis also but with no luck.

Any help appreciated!

    I'm trying to do the same thing. And show negatives did not do it for me. You?

      cbslc665 The bar chart layer will always show bars above the surface. There is no visualization for showing things below the surface. Few map platforms support that type of visualization. That said, you could combine a set of layers here. Use the bar chart to show the absolute value of the depth and maybe color it accordingly to indicate it is a negative value, and then use the bubble layer to show the magnitude based on the radius.

        I was attempting to do just that with azure maps. But it seems the layers that can do a bubble and a bar only show the same data point. What I want to show is a quantity and a depth. The quantity can be a bubble and the depth can be a bar. But I have not figured out how to do that. I can only do quantity or depth - just a single field. Is there another way?
