I have a Table ChartWrapper that is filtered by a CategoryFilter. I
have a statechange event listener on the CategoryFilter. After the
state change, I want to read just the filtered records from the
Chartwrapper, but I can't see to access them. I thought I would be
able to access the data records through table.getChart(), but I an
having trouble and see in the documentation (http://code.google.com/
apis/chart/interactive/docs/gallery/table.html ) that I can
getSelection(), but I can't get number of rows, or actually access the
rows with getValue(). I would try to select all the records in the
wrapper, then access the selection, but I don't know how to do that
without being able to at least get the count of them. Am I missing
something here? any suggestions would be appreciated. thanks
LocDataTab = response.getDataTable();
aliasFilter = new
google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'containerId': 'AliasCombo_div',
'options': {
'filterColumnIndex': 0,
'ui': {'labelStacking': 'horizontal',
'selectedValuesLayout':
'belowStacked' // 'height': '150px'},
}
}
});
ALtable = new google.visualization.ChartWrapper({
'chartType': 'Table',
'containerId': 'AllLocsTable_div',
'view': {'columns': [0,1,2,3,4,5,6,7]} ,
//"allowHtml": true,
'options': {'height': '190px', }
});
var LocVis = new
google.visualization.Dashboard(document.getElementById('AllLocsTable_div')).
bind([aliasFilter], ALtable);
google.visualization.events.addListener(ALtable, 'ready',
onReady);
google.visualization.events.addListener(ALtable, 'select',
selectHandler);
google.visualization.events.addListener(aliasFilter,
'statechange',
mapIt);
LocVis.draw(LocDataTab); //options {height:300}
