Hello,
I'm hoping someone can point out to me what I'm missing here in my understanding of how the Map visual works. I encountered a problem with this visual in one of my projects and I slowly tore down each aspect of the project thinking it had something to do with a relationship, measure or calculated column I was using somewhere. Ultimately I reduced the entire thing to a simple 3 column table with no relationships and it's still happening.
I have a table with 3 columns representing Towns and Counties in a state. Town, County and TownFullAddr. Here is the first 3 rows for an example:
| Town | County | TownFullAddress |
| Abington | Plymouth | Abington, MA, USA 02351 |
| Acton | Middlesex | Acton, MA, USA 01718 |
| Acushnet | Bristol | Acushnet, MA, USA 02743 |
The whole table is 361 rows. A few towns are repeated due to another column I had which I deleted, which would have made all the rows unique. But the same problem occurred in either situation. The problem is as follows:
1. I have "TownFullAddress" set to "Location". This creates a "bubble" for each town in the state. It works fine.
2. I then set "Town" to the "Legend". This color codes the bubbles so towns each have a unique color. So far so good.
3. As soon as I try to set "County" to "ToolTips", all of a sudden a bunch of the bubbles disappear. Strangely, if I remove that and assign it to "Latitude" or "Longitutde" (just as a test, I know it makes no sense), the same thing happens - bubbles disappear.
4. If I use "County" as the legend, no bubbles disappear. It's only when I use "Town" as legend and "TownFullAddress" as Location. When those two are true, any column I try to apply to "Latitude", "Longitude", "Bubble Size", or "ToolTips" causes a large portion of the bubbles to disappear.
Can anyone explain why this happens?
