I actually had found a (dirty) workaround just before seing your reply. I
was suspecting the date type to be a problem. By converting it to string, I
managed to get the bars to show:
var rebuiltData = new google.visualization.DataTable();
for (i=0; i< currentDisplayData.getNumberOfColumns(); i++) {
if (i == 0) {
rebuiltData.addColumn('string',
currentDisplayData.getColumnLabel(i));
} else {
rebuiltData.addColumn(currentDisplayData.getColumnType(i),
currentDisplayData.getColumnLabel(i));
}
}
for (i=0; i< currentDisplayData.getNumberOfRows(); i++) {
var colArr = new Array();
for (j=0; j< currentDisplayData.getNumberOfColumns() ; j++ ) {
if (j==0) {
colArr.push(currentDisplayData.getFormattedValue(i,
j).toString());
} else {
colArr.push(currentDisplayData.getValue(i, j));
}
}
rebuiltData.addRow(colArr);
}
Note that your workaround did work as well so I'm sure our problems are
related. I am using the candidate release (1.1). I have just tried with the
production release and get a different problem: the bars are showing but it
would show y-axis legend from 2000 to 2030 (not sure how it gets this idea
?), although the series themselves are ok.
