Ignite UI API Reference

ui.igSparkline

ui.igSparkline_image

The Sparkline control is a data-intense, design-simple graphic that allows end users to spot trends, variations and patterns in data in a clear and compact representation. It supports the following chart types: line, column, area, and win-loss, and displays more details using markers, tooltips, normal ranges, and trend lines.

Further information regarding the classes, options, events, methods and themes of this API are available under the associated tabs above.

The following code snippet demonstrates how to initialize the igSparkline control.

  • dataBinding

    Cancellable:
    true

    Event which is raised before data binding.
    Function takes first argument null and second argument ui.
    Use ui.owner to obtain reference to igSparkline.
    Use ui.dataSource to obtain reference to instance of $.ig.DataSource.

    Code Sample

     
    //Delegate
    $(document).delegate(".selector", "igsparklinedatabinding", function (evt, ui) {
        // Get reference to igSparkline.
        ui.owner;
        
        // Get reference to instance of $.ig.DataSource.
        ui.dataSource;
    });
     
    // Initialize
    $(".selector").igSparkline({
        dataBinding: function(evt, ui) {...}
    });      
  • dataBound

    Cancellable:
    false

    Event which is raised after data binding.
    Function takes first argument null and second argument ui.
    Use ui.owner to obtain reference to igSparkline.
    Use ui.data to obtain reference to array actual data which is displayed by chart.
    Use ui.dataSource to obtain reference to instance of $.ig.DataSource.

    Code Sample

     
    //Delegate
    $(document).delegate(".selector", "igsparklinedatabound", function (evt, ui) {
        // Get reference to igBaseChart.
        ui.owner;
        
        // Get reference to igSparkline's array data.
        ui.data;
        
        // Get reference to instance of $.ig.DataSource.
        ui.dataSource;
    });
     
    // Initialize
    $(".selector").igSparkline({
        dataBound: function(evt, ui) {...}
    });
