Heat Map not loading properly

[arinyc]

Hi,

I created a heat map some time ago based on long-lat coordinates and it was working well. Now, my heat mao suddenly doesn't show up properly - I mean the map is pretty flat without borders, roads, water surface and other visual elements on the map. I checked map settings and everything is turned on (Renderer = contour, Map elements - everything is turned on). I tried the heat map from the marketplace and from Office store, but with no difference. Does anyone know what goes wrong here? Has the Heat Map been changed or something else happens here?

Thank you!

have you refreshed your data since it was working? has something changed in the data. Best way to see what is going on with your data is to change the visual to a matrix (or make a copy ) and look in a table if you data is populating properly.

also you dont say what has changed, is the heat map smaller. It is highligting something, is it just less than before, or how has it changed?

Let me answer what has been changed. At the previous map (covers NYC), I could clearly see the roads, rivers, borders between neighbourhoods. The current map is flat without all of these elements. 
Data set has been refreshed on regular basis keeping the same table structure, data format, etc. (no changes).

I will add that recently I am also seeing the same. All land is blown-out white. Changing the type under Map Control does not change this. Existing files with maps that used to look like below (type = Dark) now look like the second image below.

Now:

Changing to Dark only makes the oceans darker.  Something is definitely wrong.

I am experiencing the same issue with the Flow Map.  Did you find a solution?
