I´m trying to centralize a map base in a chosen city. I´ve succesfully create two filters state and city to filter a map. After applying the filter the map displays only the city however I can´t define the latitude and longitude automatically and it is very hard to find the city. I have latitude and longitude in the same index as the map (mapa\_cidades\_brasil), but I´m unable to use the data from the table to centralize the map. I tried:
```auto
filters group="CIDADE" ungrouped=true
| esdocs index="mapa_brasil_cidades*"
fields="uf.keyword, nome.keyword, populacao, tx_wifi, vel_med, latitude, longitude" sort=", asc"
| alterColumn column="latitude" type="number"
| alterColumn column="longitude" type="number"
| savedMap id="4cc6bec0-5e41-11ea-87b6-cb7f060ff65e" center={mapCenter lat="latitude" lon="longitude" zoom=7.16} timerange={timerange from="now-15m" to="now"}
| render as="debug"
```
However, I can´t set latitude and longitude (center of the city) as parameters in the map.
Anyone able to help?

Hi @flaviogoncalves,
It looks like you might be missing [the `getCell` function](https://www.elastic.co/guide/en/kibana/current/canvas-function-reference.html#getCell_fn) to pass the relevant input to `mapCenter`. Currently you have:
```auto
mapCenter lat="latitude" lon="longitude" zoom=7.16
```
This is passing the literal string values `"latitude"` and `"longitude"` as arguments to the `mapCenter` function. Most likely what you are trying to do is something like this:
```auto
mapCenter lat={getCell column="latitude"} lon={getCell column="longitude"} zoom=7.16
```
This will look up the columns from the tabular data provided as context to the function.
Does this work for you? Let me know!
Cheers -
Luke

Thanks for your reply,
I´ve tried but got the following error:
[savedMap] \> Cannot read property 'map' of undefined
The easiest way would be to have a feature in the map to autocenter. Get the lowest and highest latitude and longitude of the objects selected to center and zoom accordingly.

Another interesting aspect is the coordinates adjust in real time whenever you move the map.

Yeah I agree, that'd be a helpful feature. I was going to point you to [an enhancement request for maps to add this in Github](https://github.com/elastic/kibana/issues/53831) but I was happy to discover you have already joined the conversation there 😄
