JSONデータを返すコントローラークラスにメソッドがあります：
public ActionResult ChartDataJSON()
{
Chart chart = new Chart();
DataSet ds = dbLayer.GetChartData();
DataTable dtChartData = ds.Tables[0];
List<jqplotModel> chartData = new List<jqplotModel>();
if (dtChartData .Rows.Count != 0)
{
foreach (DataRow row in dtChartData .Rows)
{
chartData.Add(new jqplotModel{ Date = DateTime.Parse(@row["Date"].ToString()), Demand= Convert.ToDouble(@row["Demand"].ToString()), Supply= Convert.ToDouble(@row["Supply"].ToString()) });
}
}
return Json(chartData, JsonRequestBehavior.AllowGet);
}
スクリプトでそれを使用する方法を知っている人はいますか? これらの行で試しましたが、チャートが表示されません
<script type="text/javascript">
$(document).ready(function () {
var types = ['Demand', 'Supply'];
var rawData = function (url, plot, options) {
var ret = null;
$.ajax({
// have to use synchronous here, else the function
// will return before the data is fetched
async: false,
url: url,
dataType: "json",
success: function (data) {
ret = data;
}
});
return ret;
};
// The url for our json data
var jsonurl = "/ChartController/ChartDataJSON";
var plotData = []
for (var i = 0; i < rawData.length; i++) {
//Parse the date.
var date = new Date(+rawData[i].Date.match(/\d+/));
plotData[i] = [date, rawData[i].Demand];
}
var plotData2 = []
for (var i = 0; i < rawData.length; i++) {
//Parse the date.
var date = new Date(+rawData[i].Date.match(/\d+/));
plotData2[i] = [date, rawData[i].Supply];
}
var plot1 = $.jqplot('chart1', [plotData, plotData2], {
height: 300,
width: 300,
title: 'Demand Supply',
dataRenderer: rawData,
dataRendererOptions: {
unusedOptionalUrl: jsonurl
},
series: [
{},
{ yaxis: 'y2axis' }
],
axes: {
xaxis: {
renderer: $.jqplot.DateAxisRenderer,
tickOptions: { formatString: '%#I %p' },
label: "Date",
tickInterval: '4 hour'
},
yaxis: {
label: "Demand",
labelRenderer: $.jqplot.CanvasAxisLabelRenderer
},
y2axis: {
label: "Supply",
labelRenderer: $.jqplot.CanvasAxisLabelRenderer
}
},
highlighter: {
show: true,
sizeAdjust: 1
},
cursor: {
show: false
},
legend: {
show: true,
labels: types,
location: 'ne'
}
});
$(window).bind('resize', function (event, ui) {
if (plot1) {
plot1.replot();
}
});
});
</script>
これを実行すると、グラフが表示されず、ページに次のような長いテキストが表示されます。

問題と、どこで、何が間違っているのかを理解するのを手伝ってくれる人はいますか?
編集:データは動的であり、データベースから取得され、コントローラー クラスでコーディングすることにより、JSON スクリプトがビューに返されることに注意してください。jqPlot で (ChartDataJSON() メソッドから) JSON オブジェクトを渡す/使用する方法を提案してください。
