Hi,
Do anyone know if the method getFormattedValue(numofrows,numofcols)
does not work in some context ?
I am trying it to use it with the ColumnChart visualization. I am
trying to select a bar on the column chart and trying to get the
values of the selected bar by calling the getFormattedValue() method.
But, everything till the line in the code before i call the above
method works fine. Nothing after that line seems to work. It is not
returning anything as result of the call.
Below is the code snippet,
function selectionHandler1()
{
alert("bar selected");
var selection = barsVisualization.getSelection();
var message = '';
alert(""+selection.length);
for (var i = 0; i < selection.length; i++) {
var item = selection[i];
if (item.row != null && item.column != null) {
var str = data1.getFormattedValue(item.row,
item.column);
alert(""+str);
message += '{row:' + item.row + ',column:' +
item.column + '} = ' + str + '\n';
alert(""+message);
}
}
I tried the same on the Code playground. There it seems to be working
fine. I compared both line by line and they are similar. But, still i
don't see anything.

Please, help me find out a solution.
Thanks,
Madhan
