Hi 

I am trying to display a remote XML data in a bar chart. Below is my code. 

<script type="text/javascript">
        $(document).ready(function() {
            $("#chart").kendoChart({
                dataSource: {
                    transport: {
                        read: {
                            url: "asat.xml",
                            dataType: "xml"
                        }
                    },
                    schema: {
                      type: "xml",
                      data: "/cCRMGetForecastByStageResponse/ForecastStages/ForecastStage",
                      model: {
                        fields: {
                          opportunitycount: "opportunitycount/text()",
                          leadscount: "leadscount/text()",
                          description: "description/text()"
                        }
                      }
                    }         
                },
                title: {
                    text: "Forecast Count by Stage"
                },
                legend: {
                    position: "top"
                },
                seriesDefaults: {
                    type: "column"
                },
                series:
                [{
                    field: opportunitycount,
                    name: "Opportunities"
                }, {
                    field: leadscount,
                    name: "Leads"
                }],
                categoryAxis: {
                    field: "description",
                    labels: {
                        rotation: -90
                    },
                    majorGridLines: {
                        visible: false
                    }
                },
                valueAxis: {
                    labels: {
                        format: "N0"
                    },
                    majorUnit: 1,
                    line: {
                        visible: false
                    }
                },
                tooltip: {
                    visible: true,
                    format: "N0"
                }
            });    
        });
    </script>


My XML is as below,

<?xml version="1.0"?>
<cCRMGetForecastByStageResponse xmlns="http://www.pronto.net/crm/1.0">
  <ForecastStages>
    <ForecastStage>
      <description>Initial Stage</description>
      <opportunycount>2</opportuny-count>
      <opportunyamount>1256</opportuny-amount>
      <leadscount>0</leads-count>
      <leadsamount>0</leads-amount>
    </ForecastStage>
    <ForecastStage/>
    <ForecastStage>
      <description>First Stage</description>
      <opportunitycount>1</opportunitycount>
      <opportunyamount>100</opportuny-amount>
      <leadscount>1</leadscount>
      <leadsamount>80000</leads-amount>
    </ForecastStage>
  </ForecastStages>
</cCRMGetForecastByStageResponse >


When I run it, an error comes saying opportunitycount is not defined. 

When I use the same data in a json (without the schema section above), it works. 

Is there a way to directly bind XML elements in series section? 

Thanks in advance,
Ishan

PS: I personally think your example should cover XML data binding as well. Almost all examples are based on JSON.

Hello,

The XML you provided appears to be invalid, more specifically the closing tags do not match the opening tags - opportunitycount / opportuny-count.
You may handle the data source error event to notified for such problems.
