My Code

if (response.d.length > 0) {
var dataalready = [];
var datasoafare = [];
var dataplan = [];
var datapending = [];//['Approved', 'Pending', 'Rejected'];
var datalabel = [];
var mycolor = ['#f0ad4e', '#5cb85c', '#FF0000', '#c09c61'];
var tooltiptext = [];

$('#div_cyclename').text('Cycle Name : ' + response.d[0].Cyclename);
$('#' + '<%=dtfromexpected.ClientID%>' + '_dtfromexpectedDate').val(response.d[0].startDate);
$('#' + '<%=dttoexpected.ClientID%>' + '_dttoexpectedDate').val(response.d[0].expirydate);

for (var i = 0; i < response.d.length; i++) {
dataplan.push(response.d[i].plantobeupload);
datasoafare.push(response.d[i].total_sofareupload);
datapending.push(response.d[i].tobeupload);
datalabel.push(response.d[i].DeparttName + ' ( ' + response.d[i].plantobeupload + ' )');
