    $('canvas.LineChart').each(function(cnvindx, cnvobj) {
var proc_id = $(cnvobj).data('proc_id');
    var dcharry         = [];
    var labelChartArr   = [];
    var ctxs = cnvobj;
    var dataChart = {
        datasets: [],
    labels: []
};

    var optionsChart = {
        title: {
        display: true,
    text: "Offered Call's Hourly",
    position: 'top'
},
    legend: {
        display: true,
    position:'top',
    align:'start',
},
    tooltips: {
        enabled: false
},
    plugins: {
        datalabels: {
        anchor: 'end',
    align: 'end',
    labels: {
        value: {
        color: 'blue'
}
}

}
}
};

    var myLineChart = new Chart(ctxs, {
        type: 'line',
    data: dataChart,
    options: optionsChart
});

    myLineChart.data.datasets[0]    = { };
    myLineChart.data.labels     = [];
    myLineChart.update();

    if(msg.myLineChart != undefined) {
        myLineChart.data.datasets[0].data = [];

    myLineChart.data.datasets[0].label = ["Offered Call's"];
    myLineChart.data.datasets[0].fill = [false];
    myLineChart.data.datasets[0].borderColor = [Offered_Call_COLOR];

    myLineChart.data.datasets[0].backgroundColor = [];

    $.each(msg.multiplebarchart, function(indx, hourData) {

        //setting line data 
        myLineChart.data.datasets[0].data.push(hourData['Offered_Call']);

    //setting X axis label
    myLineChart.data.labels.push(hourData['HOUR1']);

    //setting background color
    myLineChart.data.datasets[0].backgroundColor.push(Offered_Call_COLOR);
});
    myLineChart.update();
    myLineChart.render({
        duration: 500,
    lazy: false,
});
}
});
