JET Custom Elements

JET components are implemented as custom HTML elements. In addition to the component attributes documented in this page, JET components also support standard HTML global attributes like id and aria-label.

The JET data binding syntax can be used to define both component and global attributes through the use of dynamically evaluated expressions. All attributes (component and global) support attribute-level binding by prefixing the attribute name with ":" (e.g. :id="[...]"). When using attribute-level binding, all expression values are treated as strings. Additionally, component attributes support property-level binding by using the attribute name directly with no ":" prefix. When using property-level binding, the expressions should evaluate to the types documented by the corresponding attributes. Property-level binding is strongly recommended over attribute-level binding for component attributes.

A detailed description of working with custom HTML elements can be found in: JET Custom Element Usage.

JET Sunburst

Sunbursts are used to display hierarchical data across two dimensions, represented by the size and color of the sunburst nodes.


<oj-sunburst
   nodes='[{"value": 100, "color": "#FFFF00", "label": "Total Sales",
            "nodes": [{"value": 75, "color": "#00FF00", "label": "Candy"},
                      {"value": 20, "color": "#FFFF00", "label": "Fruit"},
                      {"value": 15, "color": "#FF0000", "label": "Vegetables"}]}]'>
</oj-sunburst>

Accessibility

The application is responsible for populating the shortDesc value in the component properties object with meaningful descriptors when the component does not provide a default descriptor. Since component terminology for keyboard and touch shortcuts can conflict with those of the application, it is the application's responsibility to provide these shortcuts, possibly via a help popup.

Performance

Animation

Animation should only be enabled for visualizations of small to medium data sets. Alternate visualizations should be considered if identifying data changes is important, since all nodes will generally move and resize on any data change.

Data Set Size

As a rule of thumb, it's recommended that applications only set usable data densities on this element. Applications can enable progressive reveal of data through drilling or aggregate small nodes to reduce the displayed data set size.

Styling

Use the highest level property available. For example, consider setting styling properties on nodeDefaults, instead of styling properties on the individual nodes. The sunburst can take advantage of these higher level properties to apply the style properties on containers, saving expensive DOM calls.

Tracking Resize

By default, the element will track resizes and render at the new size. This functionality adds a small overhead to the initial render for simple elements like gauges or spark charts, which become noticable when using large numbers of these simple elements. To disable resize tracking, set trackResize to off. The application can manually request a re-render at any time by calling the refresh function.

Reading direction

As with any JET component, in the unusual case that the directionality (LTR or RTL) changes post-init, the component must be refresh()ed.

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

contextMenu

The contextMenu slot is set on the oj-menu within this element. This is used to designate the JET Menu that this component should launch as a context menu on right-click, Shift-F10, Press & Hold, or component-specific gesture. If specified, the browser's native context menu will be replaced by the JET Menu specified in this slot.

The application can register a listener for the Menu's ojBeforeOpen event. The listener can cancel the launch via event.preventDefault(), or it can customize the menu contents by editing the menu DOM directly, and then calling refresh() on the Menu.

To help determine whether it's appropriate to cancel the launch or customize the menu, the ojBeforeOpen listener can use component API's to determine which table cell, chart item, etc., is the target of the context menu. See the JSDoc of the individual components for details.

Keep in mind that any such logic must work whether the context menu was launched via right-click, Shift-F10, Press & Hold, or component-specific touch gesture.

nodeTemplate

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

The nodeTemplate slot is used to specify the template for creating nodes of the sunburst. The slot content must be wrapped in a <template> element. The content of the template should be a single <oj-sunburst-node> element. See the oj-sunburst-node doc for more details.

When the template is executed for each node, it will have access to the components's binding context containing the following properties:

  • $current - an object that contains information for the current node. (See the table below for a list of properties available on $current)
  • alias - if 'as' attribute was specified, the value will be used to provide an application-named alias for $current.
Properties of $current:
Name Type Description
componentElement Element The <oj-sunburst> custom element
data Object The data object of the node
index number The zero-based index of the current node
key any The key of the current node
parentData Array An array of data objects of the outermost to innermost parents of the node
parentKey any The key of the parent node

rootNodeContentTemplate

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

The rootNodeContentTemplate slot is used to specify custom root node content for a sunburst. This slot takes precedence over the rootNodeContent.renderer property if specified.

When the template is executed, the component's binding context is extended with the following properties:

  • $current - an object that contains information for the root node. (See oj.ojSunburst.RootNodeContext for a list of properties available on $current)

tooltipTemplate

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

The tooltipTemplate slot is used to specify custom tooltip content. This slot takes precedence over the tooltip.renderer property if specified.

When the template is executed, the component's binding context is extended with the following properties:

  • $current - an object that contains information for the current node. (See oj.ojSunburst.TooltipContext for a list of properties available on $current)

touch-response :"touchStart"|"auto"

Data visualizations require a press and hold delay before triggering tooltips and rollover effects on mobile devices to avoid interfering with page panning, but these hold delays can make applications seem slower and less responsive. For a better user experience, the application can remove the touch and hold delay when data visualizations are used within a non scrolling container or if there is sufficient space outside of the visualization for panning. If touchResponse is touchStart the element will instantly trigger the touch gesture and consume the page pan events. If touchResponse is auto, the element will behave like touchStart if it determines that it is not rendered within scrolling content and if panning is not available for those elements that support the feature.
Supported Values:
Value
