JET Chart

JET Chart with support for bar, line, area, combination, pie, scatter, bubble, funnel, box plot, and stock chart types.

The SVG DOM that this component generates should be treated as a black box, as it is subject to change.

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.

The application is also responsible for including contextual information for screen readers using one or more the following methods as appropriate: aria-label, aria-labelledby, aria-describedby.

If style-defaults.data-label-outline is set to 'off', the application is also responsible for ensuring that the data label color meets the minimum contrast ratio against all possible data label background colors like series colors, plot area background color, or chart background color.

Migration

Read about current Core Pack limitations to decide when to migrate.
Please make note of the following:

oj-chart is being broken down into multiple core pack chart components (oj-c-line-chart, oj-c-area-chart, oj-c-bar-chart, etc) according to the type of the chart. To migrate from oj-chart to new core pack chart components (oj-c-area-chart, oj-c-line-chart), you need to revise the import statement and references of oj-chart in your app. JET 16.0.0 core pack has support for only oj-c-line-chart and oj-c-area-chart. Oj-c-line-chart is analogous to oj-chart with type set to ‘line’, and oj-c-area-chart is analogous to oj-chart with type set to ‘area’. Support for other chart types will be added in upcoming versions of JET. Please note the changes below.
animation-on-data-change

For the initial version of oj-c-line-chart and oj-c-area-chart, animaton-on-data-change attribute is not supported. We plan on supporting this use case in a future release.

animation-on-display

For the initial version of oj-c-line-chart and oj-c-area-chart, animaton-on-display attribute is not supported. We plan on supporting this use case in a future release.

coordinate-system

For the initial version of oj-c-line-chart and oj-c-area-chart, coordinate-system attribute is not supported. We plan on supporting this use case in a future release.

data-label

For the initial version of oj-c-line-chart and oj-c-area-chart, data-label attribute is not supported. We plan on supporting this use case in a future release.

dnd

For the initial version of oj-c-line-chart and oj-c-area-chart, dnd attribute is not supported. We plan on supporting this use case in a future release.

drag-mode

For the initial version of oj-c-line-chart and oj-c-area-chart, drag-mode attribute is not supported. We plan on supporting this use case in a future release.

initial-zooming

For the initial version of oj-c-line-chart and oj-c-area-chart, initial-zooming attribute is not supported. We plan on supporting this use case in a future release.

overview

For the initial version of oj-c-line-chart and oj-c-area-chart, overview attribute is not supported. We plan on supporting this use case in a future release.

polar-grid-shape

For the initial version of oj-c-line-chart and oj-c-area-chart, polar-grid-shape attribute is not supported. We plan on supporting this use case in a future release.

sorting

For the initial version of oj-c-line-chart and oj-c-area-chart, sorting attribute is not supported. We plan on supporting this use case in a future release.

For the initial version of oj-c-line-chart and oj-c-area-chart, split-dual-y attribute is not supported. We plan on supporting this use case in a future release.

splitter-position

For the initial version of oj-c-line-chart and oj-c-area-chart, splitter-position attribute is not supported. We plan on supporting this use case in a future release.

stack-label

For the initial version of oj-c-line-chart and oj-c-area-chart, stack-label attribute is not supported. We plan on supporting this use case in a future release.

stack-label-provider

For the initial version of oj-c-line-chart and oj-c-area-chart, stack-label-provider attribute is not supported. We plan on supporting this use case in a future release.

zoom-direction

For the initial version of oj-c-line-chart and oj-c-area-chart, zoom-direction attribute is not supported. We plan on supporting this use case in a future release.

type

Corepack chart components (oj-c-line-chart, oj-c-area-chart) will not support the type attribute. Each type of chart will be broken down into separate core pack component.

touch-response

For the initial version of oj-c-line-chart and oj-c-area-chart, coordinate-system attribute is not supported. We plan on supporting this use case in a future release.

track-resize

For the initial version of oj-c-line-chart and oj-c-area-chart, track-resize attribute is not supported. The component will itself resize on change in dimension.

Performance

Animation

Animation should only be enabled for visualizations of small to medium data sets. When animating changes to larger data sets or when animating between data sets, it's recommended to turn off the styleDefaults.animationIndicators, since they effectively double the amount of work required for the animation.

Data Set Size

As a rule of thumb, it's recommended that applications only set usable data densities on the chart. For example, it's not recommended to show more than 500 bars on a 500 pixel wide chart, since the bars will be unusably thin. While there are several optimizations within the chart to deal with large data sets, it's always more efficient to reduce the data set size as early as possible. Future optimizations will focus on improving end user experience as well as developer productivity for common use cases.

Styling

Use the highest level property available. For example, consider setting styling properties on styleDefaults or series, instead of styling properties on the individual data items. The chart 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.

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.

groupTemplate

The groupTemplate slot is used to specify the template for generating the group properties of the chart. The slot content must be a single <template> element. The content of the template should only be one <oj-chart-group> element. See the oj-chart-group doc for more details.

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

  • $current - an object that contains information for the current item. (See oj.ojChart.GroupTemplateContext or the table below for a list of properties available on $current)
  • alias - if data-oj-as attribute was specified, the value will be used to provide an application-named alias for $current.
Properties of $current:

touch-response :"touchStart"|"auto"

Data visualizations require a press and hold delay before triggering tooltips, marquee selection, 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 the element does not require an internal feature that requires a touch start gesture like panning, zooming, or when marquee selection is initiated. 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:
