Data Binding
The ChartWiizard component provides different options for binding data. You can bind the component to an array of data, use a Grid selection or bind it to a table-like data.
Binding to Array
You can bind the ChartWizard component to a local or remote data array.
The bound data must contain one or more arrays of objects with field and value properties.
The following example demonstrates how to bind the Chart Wizard to an array of data.
<div id="chartwizard"></div>
$("#chartwizard").kendoChartWizard({
dataSource: [
[
{ field: 'Product Name', value: 'Calzone' },
{ field: 'Quantity', value: 1 },
{ field: 'Price', value: 12.39 },
{ field: 'Tax', value: 2.48 },
{ field: 'Total', value: 14.87 }
]
],
});
When the ChartWizard is bound to remote data, the remote service must return one or more arrays of objects with field and value properties. The example below demonstrates how to bind the ChartWizard to remote data:
<div id="chartwizard"></div>
<script>
var chartwizard = $("#chartwizard").kendoChartWizard({
dataSource: {
transport: {
read: {
url: "../content/dataviz/js/wizard-products.json",
dataType: "json"
}
}
}
}).data("kendoChartWizard");
</script>
Binding to Grid Selection
The ChartWizard lets you bind the component to selected Grid cells or rows:
For more details, refer to the Chart Integration article in the Grid documentation.
For a live demo, see How to create Charts from selected Grid cells or rows by using the Kendo ContextMenu.
Binding to Table-Like Data
ChartWizard component accepts table-like data comprising an array of objects with dataItem and dataColumns fields.
To bind the Chart Wizard component to table-like data, create a DataRow collection and use the getWizardDataFromDataRows helper method to convert it to the format required by the ChartWizard.
The example below demonstrates ChartWizard bound to local table-like data:
<div id="chartwizard"></div>
<script>
const dataColumns = [
{
field: 'Product',
title: 'Product Name'
},
{
field: 'Quantity',
title: 'Quantity'
}
];
const dataRows = [
{
dataItem: {
ID: 216321,
Product: 'Calzone',
Quantity: 1
},
dataColumns
},
{
dataItem: {
ID: 546897,
Product: 'Margarita',
Quantity: 2
},
dataColumns
},
{
dataItem: {
ID: 456231,
Product: 'Pollo Formaggio',
Quantity: 1
},
dataColumns
}
];
const chartWizardData = kendo.ChartWizard.getWizardDataFromDataRows(dataRows);
var chartwizard = $("#chartwizard").kendoChartWizard({
dataSource: chartWizardData
}).data("kendoChartWizard");
</script>
To bind the ChartWizard component to a remote data source, which returns only the dataItems, set the dataColumns field.
<div id="chartwizard"></div>
<script>
var dataSource = new kendo.data.DataSource({
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
schema: {
model: {
fields: {
OrderID: { type: "number" },
Freight: { type: "number" },
ShipName: { type: "string" },
OrderDate: { type: "date" },
ShipCity: { type: "string" }
}
}
},
pageSize: 20,
serverPaging: true,
serverFiltering: true,
serverSorting: true
});
$("#chartwizard").kendoChartWizard({
dataSource: dataSource,
dataColumns: [
{
field: "OrderID",
},
{
field: "Freight",
},
{
field: "ShipName",
title: "Ship Name"
}, {
field: "ShipCity",
title: "Ship City"
}
],
});
</script>
