Google Visualization API - Geomap regions for Germany

Question

After the release of new geomap package version I seem to have a problem using geomap for German regions. Before the upgrade everything seemed to work just fine. The problem is that if I try to show both the region DE-BE (Berlin) & DE-BB (Brandenburg) - the Berlin region is not shown. If I delete the region DE-BB, or substitute it with any other German region, for example, DE-BY (Bayern) it works fine!

Please find below test code:

google.load('visualization', '1.1', {packages: ['geomap']});

function drawVisualization() {
      var data = new google.visualization.DataTable();
      data.addRows(2);
      data.addColumn('string', 'Country');
      data.addColumn('number', 'Popularity');
      data.setValue(0, 0, 'DE-BE');
      data.setValue(0, 1, 200);
      data.setValue(1, 0, 'DE-BB');
      data.setValue(1, 1, 300);

      var geochart = new google.visualization.GeoMap(document.getElementById('visualization'));

      var options = {};
      options['dataMode'] = 'regions';
      options['region'] = 'DE';

      geochart.draw(data, options);
    }

google.setOnLoadCallback(drawVisualization);

Could you please provide me with any support or ideas what might have gone wrong? Is it possible to include the old version of geomap package for testing?

Answer 1

Use the resolution option parameter

options['resolution'] = 'provinces';

Also the api now has a new GeoChart format which gives you even more customization such as changing the background color to match your website theme.
