c# - jqPlot not working with dates -


i'm new using json, , i'm trying generate jqplot dates on x-axis , numbers on y-axis. this, i'm passing data json string view. however, jqplot not being generated.

here code in view:

<script type="text/javascript">     $(document).ready(function () {         var plot = $.jqplot('placeholder', @viewbag.chart, {             title: 'visual report',             axes: {                 xaxis: { renderer: $.jqplot.dateaxisrenderer }             }         });     }); </script>

i'm using newtonsoft.json.jsontextwriter create json string; can have this?

    private string json(dictionary<string, dictionary<string, list<point>>> points, string radio)     {         var sb = new stringbuilder();         var sw = new stringwriter();         using (var jsonwriter = new jsontextwriter(sw))          {             jsonwriter.writestartarray();             foreach (var merchant in points)             {                 foreach (var type in merchant.value)                 {                     jsonwriter.writestartarray();                     foreach (var point in type.value)                     {                         jsonwriter.writestartarray();                         jsonwriter.writevalue(point.date.value.tostring("yyyy-mm-dd"));                         if (radio == "amount")                         {                             jsonwriter.writevalue(point.sumamount);                         }                         else                         {                             jsonwriter.writevalue(point.countamount);                         }                         jsonwriter.writeendarray();                     }                     jsonwriter.writeendarray();                 }             }             jsonwriter.writeendarray();         }         string result = sw.tostring();         return result;     }

when replace line

jsonwriter.writevalue(point.date.value.tostring("yyyy-mm-dd"));

with 

jsonwriter.writevalue(point.sumamount);

the chart magically appears (after comment out axes options). seems problem stems parsing of dates in json string, still doesn't work after tried using jquery.parsejson() , json.parse(). doing wrong here?

update: although wasn't able resolve issue, managed achieve wanted (more or less) through ajax (which proved have own learning curve, that's story day).
