I have a ControlWrapper and a Bar Chart
var data = new google.visualization.DataTable();
data.addColumn('date', 'Dato');
data.addColumn('number', 'Vægt forandring');
data.addColumn('number', 'Samled vægt');
data.addRow([new Date(2012,05,02), 2.00,27.20]);
data.addRow([new Date(2012,05,03), 0.20,32.10]);
data.addRow([new Date(2012,05,04), -0.30,31.80]);
data.addRow([new Date(2012,05,05), 0.01,31.80]);
data.addRow([new Date(2012,05,06), -0.40,31.40]);
data.addRow([new Date(2012,05,07), 0.00,31.40]);
data.addRow([new Date(2012,05,08), -0.30,31.10]);
data.addRow([new Date(2012,05,09), -0.30,30.80]);
data.addRow([new Date(2012,05,10), -0.50,30.30]);
I have a event that give my the start and end of selected data.
how do I get the sum of selected data
For example, if the first and last one is the start and end.
data.addRow([new Date(2012,05,04), -0.30,31.80]);
data.addRow([new Date(2012,05,05), 0.01,31.80]);
data.addRow([new Date(2012,05,06), -0.40,31.40]);
data.addRow([new Date(2012,05,07), 0.00,31.40]);
so that the first is not used.
I would like to have 0.01 + -0.4 + 0.00 = -0.39
How do I do it?
google.visualization.events.addListener(control, 'statechange',
function(event) {
//document.getElementById('veight').value
=control.getState()["range"]["end"];
document.getElementById('veight').value
=control.getState()["range"]["start"];
//document.getElementById('veight').value = data;
}
);
