Hi,
I am rendering a typical time based column-chart (x-axis time, y-axis
count).
On server side I am rendering respective js-code:
===
var timeData = new google.visualization.DataTable();
timeData.addColumn('string', 'Details');
timeData.addColumn('number', 'Count');
// time info as weekdays
timeData.addRow(["Su",321]);
timeData.addRow(["Mo",12]);
timeData.addRow(["Tu",14]);
As I want to make zooming possible (clicking on a column would open
new request) I am attaching a callback:
===
google.visualization.events.addListener(chart, 'select',
function() {
window.location.href = "http://xxyy"; + $("chart.getSelection()
[0].row).attr('href');
location.load();
);
In this case 'chart.getSelection()[0].row' is not accurate enough (I
only get weekday like 'Su', but I need '2012-01-01/12:00:00'. I tried
to get this done by adding a 3rd row 'timeData.addRow(["Su",
321,"2011-01-01/12:00:00"]);' but this causes graph rendering more
columns.
Is there a way to attach data to chart-data object, which is hidden
and not displayed on chart at all?
thanks.
