gwt - Inserting JSON in DataTable in Google Visualisation -

-

i read json can inserted datatable. however, done in js on html page (if memory serves right). using gwt- visualisation driver given here, , methods add row not designed json in mind. there work-able solution? trying make stacked column chart. thanks.

i struggled using geomap , data table combined. in workaround used evaljson() in prototype javascript framework make json string object.

var country_obj = country_data.evaljson(true);

then loop on object's length :

var data = new google.visualization.datatable(); data.addrows(country_obj.country.length); data.addcolumn('string', 'country'); data.addcolumn('number', map_context);   var j = country_obj.country.length; ( = 0; < j; i++ ) {     var num = new number(country_obj.country[i].geo_mstat_reads);      data.setvalue(i, 0, country_obj.country[i].country_name);     data.setvalue(i, 1, num.valueof()); }  // , table.draw() data

this worked me because scales exact size of dataset trying show.

also can whole whack of operations on object makes life , coding easier read , write.

i hope helps problem.
