            datasets : [
                {
                    fillColor : "#48A497",
                    strokeColor : "#48A4D1",
                    data : [456,479,324,569,702,600]
                },

                    fillColor : "rgba(73,188,170,0.4)",
                    strokeColor : "rgba(72,174,209,0.4)",
                    data : [364,504,605,400,345,320]
                }
            ]
        }
        // get bar chart canvas
        var income = document.getElementById("income").getContext("2d");
        // draw bar chart
        new Chart(income).Bar(barData);
