Re: How do you change the center of a GeoChart?

Hi, unfortunately there is no such option at this time. I'm afraid that the best that you can currently do is to set the 'region' option to 'auto' and that will pick the map that includes all of your markers.

I'm working with marine scientists and they take samples off the coast. I would like to change the center of the chart to be off the coast. I would like to give a latitude/longitude pair for the center of the chart, or two latitude/longitude pairs for a window/view of the map area, or specify multiple states like US-CT-NY. I'm hoping there is a hidden API like geochart.center = {lat: 89, long: -127}.

function drawVisualization() {

  var data = google.visualization.arrayToDataTable([

    ['Lat', 'Long', 'Popularity'],

    [41.083333333276, -73.39999999978, 20.4 ],

    [41.099550000113, -73.415400000078, 19.0 ]

  var options = {title:'Temperature', region:'US-CT', resolution:'metros', width: 556, height: 347};

  var geochart = new google.visualization.GeoChart(

      document.getElementById('visualization'));

  geochart.draw(data, options);

That doesn't help. Some of the data is bad, and it gives errors like  Requested map does not exist.

For example, try adding these lines:

    [41.083333333276, -52.39999999978, 18.6 ],

  var options = {title:'Temperature', region:'auto', resolution:'metros',  width: 556, height: 347};

Unfortunately, you're right. One way to fix this is to specify the resolution to be 'provinces' or 'countries', but that seems to be even more broken. I don't have any better advice for you at this time.
