I created a Flot Chart but I found out that when pass 1 or 0 for only one month and load the graph the Y axis shows some long decimal numbers. Please help.

var options1 =
                {
                    yaxis: { axisLabel: ""},
                    xaxis: {
                        tickLength: 1,
                        axisLabel: "Months",
                        ticks: [[1, "Jan"], [2, "Feb"], [3, "Mar"], [4, "Apr"], [5, "May"], [6, "Jun"], [7, "Jul"], [8, "Aug"], [9, "Sep"], [10, "Oct"], [11, "Nov"], [12, "Dec"]]
                    },
                    grid: {
                        hoverable: true,
                        clickable: true
                    },
                    valueLabels: {
                        show: true
                    }
                };
