You can change to the ComboChart by replacing "BarChart" with "ComboChart"
in the ChartWrapper's "chartType" parameter, but your data isn't formatted
correctly to take advantage of the ComboChart. To make a chart like the
one in the link, you have to restructure your data so that each bar color
is represented by a column of data in your chart:
var data = google.visualization.arrayToDataTable([
['Month', 'Bolivia', 'Ecuador', 'Madagascar', 'Papua New Guinea',
'Rwanda', 'Average'],
['2004/05', 165, 938, 522, 998,
450, 614.6],
['2005/06', 135, 1120, 599, 1268,
288, 682],
['2006/07', 157, 1167, 587, 807,
397, 623],
['2007/08', 139, 1110, 615, 968,
215, 609.4],
['2008/09', 136, 691, 629, 1026,
366, 569.6]
]);
See how each country has its own column? That is how you have to structure
your data to take advantage of the ComboChart.
