Where is Axis-Y input value for Stacked Bar flot chart

[Alouty]

Can help me to find out where is the input data for axis Y? It is randomly generated values. I want to replace it with my own array: 1,3,254,46,2,35,243 or 11,13,254,146,12,35,243. I know axis-X is 1 to 10 (month) - I will keyin smarty var for axis X.

   function d(k) {
    var n = [];
    for(var e = 0; e <= 10; e += 1) {
        n.push([e, parseInt(Math.random() * 30)])
    }
    var m = [];
    for(var e = 0; e <= 10; e += 1) {
        m.push([e, parseInt(Math.random() * 30)])
    }
    var j = [];
    for(var e = 0; e <= 10; e += 1) {
        j.push([e, parseInt(Math.random() * 30)])
    }
    var l = {
        series: {
            stack: true,
            bars: {
                show: true,
                barWidth: 0.4
            }
        },
        grid: {
            borderWidth: 0
        }
    };
    a.plot(k, [{
        data: n,
        color: "#E15656"
    }, {
        data: m,
        color: "#A6D037"
    }, {
        data: j,
        color: "#61A5E4"
    }], l)
}
