将其数据坐标简单修改为时间戳，如下列形式，然后设置x坐标轴类型为时间，
我发现只要时间戳不是连续的数字，热力图就会渲染成条状。。

`
var noise = getNoiseHelper();
var xData = [];
var yData = [];
noise.seed(Math.random());
function generateData(theta, min, max) {

var data = [];
for (var i = 0; i <= 100; i++) {
    for (var j = 0; j <= 300; j++) {
        // var x = (max - min) * i / 200 + min;
        // var y = (max - min) * j / 100 + min;
        data.push([new Date().getTime()+1000*i,j,noise.perlin2(i / 40, j / 20) + 0.5]);
        // data.push([i, j, normalDist(theta, x) * normalDist(theta, y)]);
    }
}
for (var j = 0; j < 100; j++) {
    yData.push(j);
}
return data;

}
var data = generateData(2, -5, 5);
