Geo Chart Specific Province or Crop Function

[Henrique Vilela]

Hi,

I'm trying to display data about cities in a specific Brazilian province. To to this I'm using { region: 'BR', resolution: 'provinces', displayMode: 'markers' }

The problem is that all the points are concentrated in a small area of the map (attached image).

There's a way to select a specific province or to "crop" de map to focus on the real data?

[Sergey Grabkovsky]

Hi, there's no way to recrop the map to be exactly what you want. For some countries, we generate province-level maps, but it appears that Brazil is not one of those countries. Please file a bug against this, this as it would be good to have these maps.

Thank you for your fast answer.

I just wan’t to be sure that my needs are clear.

I don’t need a different map, all that I need is to “zoom in” to avoid the empty space around the data, without adding any kind of "level of detail".

Even this is not possible with Google GeoChart?

Would you recommend any alternative? Google Maps, maybe?

Actually, come to think of it, the Map visualization is much better suited for these kinds of charts.

[Henrique Vilela]

I don’t think so.

It will add complexity to a simple task, and I will lose automatic features like the color values and the color legend that I’ll have to implement.

GeoChart is perfect to solve my problem, except by this little missing feature.

[Sergey Grabkovsky]

Ah, well in that case, I don't think we have a solution for you. The right thing would be for us to provide a province-level map for BR-RS, and then that province would effectively be the only region on the map, but as I said, this region is not available, and there's no way to change the bounding box of the currently displayed region.

[Henrique Vilela]

Got it.

Thank you so much for your time.

Anyone with an alternative simpler than recreate the pins with color and size based on the value and legend over Google Maps, please let me know. :)

Hi Sergey,

Is this possible to set a bounding box for other countries like USA on Geo Chart? Ex: display only North east states etc. Please advise. Thanks!

You can add a magnifying glass feature which when you hover over that area it will magnify it. 

Just add this in your options 

magnifyingGlass : {enable: true, zoomFactor: 7.5}
