问题

I have a kendo-chart with the below Json data sample.I have to show the data like in the two X- Axis one with Iron Type and other with manufacturer.Let me explain with an example. I have iron types as Swivel and Adapter.And manufacturers as SPM and FMC. Now in the X-axis under Swivel Iron type i have to show FMC ans SPM bar chart against Total Failed,Total passed and Total Processed. and one line chart based on percentage.

Can anyone help me on this how to achieve with the below data.

[
  {"IronType":"Adapter","Manufacturer":"FMC","TotalFailed":56,"TotalPassed":1016,"TotalProcessed":1072,"FailedVTotalInspected":5.22},
  {"IronType":"Adapter","Manufacturer":"SPM","TotalFailed":36,"TotalPassed":613,"TotalProcessed":649,"FailedVTotalInspected":5.55},
  {"IronType":"Swivel","Manufacturer":"FMC","TotalFailed":984,"TotalPassed":5094,"TotalProcessed":6078,"FailedVTotalInspected":16.19},
  {"IronType":"Swivel","Manufacturer":"SPM","TotalFailed":299,"TotalPassed":1051,"TotalProcessed":1350,"FailedVTotalInspected":22.15}

Given your json data, you can filter for the IronType you want to display in the dataSource object:

var dsCertpData = new kendo.data.DataSource({
    data: theData,
    filter: { field: "IronType", operator: "eq", value: "Swivel" }
}); 

      $("#chart1").kendoChart({
        theme: "Fiori",
        dataSource: dsCertpData,
        legend: {
          position: "right",
          visible: true,
        },
        seriesColors: ["#95B3D7","#C3D69B","#D99694","#7D60A0"],
        series: [
          {
            type: "column",
            categoryField: "Manufacturer",
            field:"TotalProcessed",
            name: "Total Processed",
            axis: "Main",
          },
          {
            type: "column",
            categoryField: "Manufacturer",
            field:"TotalPassed",
            name: "Total Passed",
            axis: "Main"
          },              {
            type: "column",
            categoryField: "Manufacturer",
            field:"TotalFailed",
            name: "Total Failed",
            axis: "Main"
          },              
          {
            type: "line",
            categoryField: "Manufacturer",
            field:"FailedVTotalInspected",
            name: "% failed",
            axis: "percent",
          }        
        ],
        categoryAxis: {
            title: { text: "Swivel" },
            axisCrossingValues: [ 10, 0],
        },
        valueAxes: [
          {
                name: "percent",
                min: 0,
                max: 100,
          },
          {
                name: "Main",
          }, 
        ], 
        tooltip: {
            visible: true,
            template: "${series.name} : ${value}"
        }
    });

Then each time a new IronType is selected, update the chart:

    var value = $("#IronTypeFilter").val();
    dsCertpData.filter( { field: "IronType", operator: "eq", value: value });

    var chart = $("#chart1").data("kendoChart");
    chart.options.categoryAxis.title.text = value;
    chart.redraw();
