GeoMap for austria with lower austria and vienna

Question

When I use gwt-visualization and GeoMap it happens that when I give a value to Vienna it works fine, but if I give a value to lower austria -> Vienna is not shown anymore on the map.

Heres the code I use to create the geomap:

private Options createOptions() {
        Options options = Options.create();
        options.setDataMode(DataMode.REGIONS);
        options.setWidth(1000);
        options.setHeight(650);
        options.setRegion("AT");
        return options;
    }

    private AbstractDataTable createTable2() {
        DataTable data = DataTable.create();
        data.addColumn(ColumnType.STRING, "Bundesland");
        data.addColumn(ColumnType.NUMBER, "Sessions");

        data.addRows(9);

        data.setValue(0, 0, "Niederösterreich");
        data.setValue(0, 1, 200);

        data.setValue(1, 0, "Salzburg");
        data.setValue(1, 1,56);

        data.setValue(2, 0, "Tirol");
        data.setValue(2, 1, 11);

        data.setValue(3, 0, "Oberösterreich");
        data.setValue(3, 1, 11);


        data.setValue(4, 0, "Burgenland");
        data.setValue(4, 1, 55);


        data.setValue(5, 0, "Vorarlberg");
        data.setValue(5, 1, 567);

        data.setValue(6, 0, "Kärnten");
        data.setValue(6, 1, 11);

        data.setValue(7, 0, "Steiermark");
        data.setValue(7, 1, 99);

        data.setValue(8, 0, "Wien");
        data.setValue(8, 1, 1);

        return data;
    }

I think the reason why this is happen is becaus lower austria surround vienna. Is there a way to get this working?

It looks like GeoMaps does not include AT-9 in its map. In your luck, GeoCharts (the non-flash newer version of GeoMaps) does.

I don't use GWT, so I won't be able to tell you how to translate this in to GWT (apologies, maybe someone else can tack on the proper syntax). Here is the code:

function drawVisualization() {
  var data = google.visualization.arrayToDataTable([
    ['Bundesland', 'Sessions'],
    ['AT-3', 200],
    ['AT-5', 56],
    ['AT-7', 11],
    ['AT-4', 11],
    ['AT-1', 55],
    ['AT-8', 567],
    ['AT-2', 11],
    ['AT-6', 99],
    ['AT-9', 1]
  ]);

  var geochart = new google.visualization.GeoChart(
      document.getElementById('visualization'));
  geochart.draw(data, {region: 'AT', resolution: 'provinces', width: 556, height: 347});
}

In general, I suggest using the ISO-3166 codes for whichever country you map to make it render faster. Let me know if it works!

createOptions() should return an object class GeoMap.Options. That may be the problem.

private GeoMap.Options createOptions() {
        GeoMap.Options options = GeoMap.Options.create();
        options.setDataMode(DataMode.REGIONS);
        options.setWidth(1000);
        options.setHeight(650);
        options.setRegion("AT");
        return options;
    }
