Greetings
I am trying to make a line chart, here is my column defition:
var dataTable = new google.visualization.DataTable();
dataTable.addColumn('date', 'Date');
dataTable.addColumn('number', 'Uptime');
dataTable.addColumn('string', 'Channel');
and a sample row input:
dataTable.setCell(0, 0, new Date(2009,08,24) );
dataTable.setCell(0, 1, 927);
dataTable.setCell(0, 2, "TV 1");
Now I want to group my rows by Channel and link their daily Uptime (so
a new line for each channel), and at the Y axis it should be the
Uptime.
How this is possible?
Thanks
