Refresh a chart with new DataSource?

[mike]

I am needing to reset my datasource to grab parameters from my page to reload the chart. Is there a way to make this happen?

Here is my code for the chart currently. I need change the querystring that goes back on the url for the remote datasource based on page values.

$("#chart").kendoChart({

  dataSource:

  {

      transport:{

          read:{

              url: "@Url.Action("BusinessUnitCompareChart")" + "?date=" + $("#DateFilter").val() + "&StructureId=" + "@ViewData["StructureId"].ToString()" + "&buids=" + "@ViewData["buids"].ToString()",

              dataType:"json"

          }

      },

      group:{ field:"Name"},

  

      sort:{

          field:"Name",

          dir:"asc"

      }

  },

  

  series:[{type:"column", field:"Count"}],

  seriesColors:["#C81717","#8E908F","#0098DB"],

  

  categoryAxis:{ field:"CategoryName"},

  

  theme:  "Metro",

  title: {

  text: "Open/ Aging/ Closed"

  },

                        

  tooltip: {

  visible: true

  },

  seriesClick: onSeriesClick

  });

I create my datasource outside my chart constructor like
var dataSource = new kendo.data.DataSource({
// Fill in all your options here
});

Then you can call dataSource.read(); and it will refetch the data. So you can manipulate the filter etc. on the dataSource, then call .read() to get the different data.
