    binding

    Gets or sets the comma-separated property names for the itemsSource property to use in axis labels.

    The first name specifies the value on the axis, the second represents the corresponding axis label. The default value is 'value,text'.

    Type
    string

    format

    Gets or sets the format string used for the axis labels (see Globalize).

    Axis
    Type
    string

    groupsOptions

    Gets or sets label groups settings for the axis.

    Label groups are created by modifying the groupDescriptions property of the ICollectionView object used as an itemsSource.

    The default value is **null** and the axis label groups are not displayed.

    To display groups you should create groups in collection view and specify the groupsOptions for the axis.

    For example,

     let view = new CollectionView( getData(), {
        groupDescriptions: [ 
          new PropertyGroupDescription('category'), 
          new PropertyGroupDescription('subCategory')]
        });
     const chart = new FlexChart('#theChart', {
        itemsSource: view,
        bindingX: 'product',
           series: [ { binding:'sales' } ],
           axisX: { groupsOptions: { display : AxisGroupsDisplay.Show } },
      });

    itemFormatter

    Gets or sets the itemFormatter function for the axis labels.

    If specified, the function takes two parameters:

    • render engine: The IRenderEngine object to be used in formatting the labels.
    • current label: An object with the following properties:
      • value: The value of the axis label to format.
      • text: The text to use in the label.
      • pos: The position in control coordinates at which the label is to be rendered.
      • cls: The CSS class to be applied to the label.

    The function returns the label parameters of labels for which properties are modified.

    For example:

    chart.axisY.itemFormatter = function(engine, label) {
        if (label.val > 5){
            engine.textFill = 'red'; // red text
            label.cls = null; // no default CSS
         }
        return label;
    }
