Bootstrap Chart.js后台动态数据前台显示不出来，求教！！！

[HI阡陌]

public ActionResult GetListChart() {

var list = db.m_product.ToList();
List<GetList> l = new List<GetList>();
StringBuilder sb = new StringBuilder();

foreach (var item in list)
{
GetList m = new GetList();
m.name = item.pname;
m.Price = item.price.ToString();
l.Add(m);
}
return Json(l,JsonRequestBehavior.AllowGet);

}
这是后台返回数据的方法，


var labless = [];
var datas = [];
var s="\"";
var Ls = "", ds="";
var data;

$.getJSON("@Url.Action("GetListChart", "Hj")", function (json) { //回调函数的参数data就是后台封装的json串

$.each(json, function (i, val) {

data = {
labels: [val.name],
datasets: [
{
barItemName: "name1",
fillColor: "rgba(201,18,18,0.5)",
strokeColor: "rgba(220,220,220,1)",
data: [val.Price]
}

]
};
//labless.push("" + val.name + "");
//datas.push("" + val.Price + "");
//labless += s + val.name + s + ",";
//datas += s + val.Price + s + ",";
labless = val.name;
datas = val.Price;
});
Ls = "[" + labless + "]";
ds = "[" + datas + "]";
//document.write(Ls+"<br />")
// document.write(ds+ "<br />")

});

这是前台绑定的方法

但是只能绑定一个，数据总g共有26条

用这种方式绑定显示数据不对，
//labless += s + val.name + s + ",";
//datas += s + val.Price + s + ",";
Ls = "[" + labless + "]";
ds = "[" + datas + "]";

求大神解决 ，弄了半天了
