JET PictoChart

PictoChart uses icons to visualize an absolute number, or the relative sizes of the different parts of a population.

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.

When using colors as a data dimension for PictoChart, the application needs to ensure that they meet minimum contrast requirements. Not all colors in the default value ramp provided by oj.ColorAttributeGroupHandler will meet minimum contrast requirements.

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 data items will generally move and resize on any data change.

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.

Layout

Fixed and Flowing Layout

PictoChart supports both fixed and flowing layout. If the element has a fixed width and height (set by the inline style, style class, etc.), then the pictoChart will use a fixed layout, which means that the shapes will be resized to occupy the given space as much as possible. Otherwise, the pictoChart will use a flowing layout, which means that the shapes are rendered at a constant size and the element will take up as much space as necessary. It is possible to fix just one of the two dimensions, and the pictoChart would still use the flowing layout.

If fixed layout is used, please avoid using the rowHeight and columnWidth attributes as they may cause the shapes to be dropped if the given space is not large enough.

Layout Orientation and Origin

PictoChart currently supports rectangular layouts with two different orientations (horizontal and vertical) and four different origins (topStart, topEnd, bottomStart, and bottomEnd). Please refer to the Pictochart cookbook demo to see how these layout attributes work.

Mixed Sizes

PictoChart supports items that are varying in sizes by specifying the columnSpan and rowSpan attributes on the items. To ensure the best layout, it is recommended that the bigger items are ordered first because the layout algorithm is greedy and will position items to the first available space.

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.

itemTemplate

The itemTemplate slot is used to specify the template for creating each item of the picto chart when a DataProvider has been specified with the data attribute. The slot content must be a single <template> element.

When the template is executed for each item, it will have access to the picto chart's binding context and the following properties:

  • $current - an object that contains information for the current item. (See oj.ojPictoChart.ItemTemplateContext or 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.

The content of the template should only be one <oj-picto-chart-item> element. See the oj-picto-chart-item doc for more details.

Properties of $current:
Name Type Description
componentElement Element The <oj-picto-chart> custom element.
data Object The data object for the current item.
index number The zero-based index of the current item.
key any The key of the current item.

tooltipTemplate

The tooltipTemplate slot is used to specify custom tooltip content. The slot content must be a single <template> element. 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 item. (See oj.ojPictoChart.TooltipContext or the table below for a list of properties available on $current)
Properties of $current:
Name Type Description
color string The color of the hovered item.
componentElement Element The picto chart HTML element.
count number The count of the hovered item.
id K The id of the hovered item.
name string The name of the hovered item.
parentElement Element The tooltip element. The function can directly modify or append content to this element.

Properties:
Name Type Argument Default Description
borderColor string <optional>
 The border color of the item. Does not apply if custom image is specified.
borderWidth number <optional>
 The border width of the item in pixels. Does not apply if custom image is specified.
categories Array.<string> <optional>
 An array of category strings corresponding to this item. If not specified, defaults to the item id or name. This enables highlighting and filtering of individual data items through interactions with other visualization elements.
color string <optional>
 The color of the item. Does not apply if custom image is specified.
columnSpan number <optional>
 The number of columns each shape (or custom image) spans. Used for creating a pictoChart with mixed item sizes.
count number <optional>
 Specifies the number of times that the shape (or custom image) is drawn. Fractional counts (such as 4.5) are supported; however, fractions other than the multiples of 0.5 should be avoided because the fractional rendering ignores the gaps between shapes and the irregularity of the shapes.
drilling "inherit" | "off" | "on" <optional>
 "inherit" Whether drilling is enabled for the item. Drillable items will show a pointer cursor on hover and fire an ojDrill event on click (double click if selection is enabled). To enable drilling for all items at once, use the drilling attribute in the top level.
id K <optional>
 The item id. The item id should be set by the application if the DataProvider is not being used.
name string <optional>
 The name of the item. Used for default tooltip and accessibility.
rowSpan number <optional>

shape "ellipse" | "square" | "circle" | "diamond" | "triangleUp" | "triangleDown" | "star" | "plus" | "human" | "none" | "rectangle" | string <optional>
 "rectangle" The shape of the item. Can take the name of a built-in shape or the SVG path commands for a custom shape. "None" will make the item transparent and can be used to create gaps. Does not apply if custom image is specified.

sourceHoverSelected string <optional>
 The optional URI for the hover selected state. If not specified, the source image will be used.
sourceSelected string <optional>
 The optional URI for the selected state. If not specified, the source image will be used.

svgStyle Partial<CSSStyleDeclaration> <optional>
 The inline style to apply to the item. The style class and inline style will override any other styling specified with other properties. For tooltip interactivity, it's recommended to also pass a representative color to the item color attribute. Does not apply if custom image is specified. Only SVG CSS style properties are supported.
