JET Line Chart

A line chart displays information graphically using data points connected by straight or curved lines, making relationships among the data easier to understand.

Accessibility

To make your component accessible, the application is required to include contextual information for screender readers using one or more the following methods as appropriate:
  • aria-describedby
  • aria-labelledby
  • aria-label
  • short-desc property of your items

If your application has custom keyboard and touch shortcuts implemented for the component, these shortcuts can conflict with those of the component. It is the application's responsibility to disclose these custom shortcuts, possibly via a datatip or help popup.

When setting color, applications are responsible for making sure that the color meets the minimum contrast requirements.

Performance

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 lines on a 500 pixel wide chart, since the lines 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.

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.

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-c-line-chart-group> element. See the oj-c-line-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 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:
Name Type Description
depth number The depth of the group. The depth of the outermost group under the invisible root is 1.
ids Array<string> The key of the current item.
index number The group index
items Array.<oj-c.LineChart.ChartItemTemplateContext> The array of objects which are chart items that belong to this series. The objects will have the following properties

itemTemplate

The itemTemplate slot is used to specify the template for creating each item of the chart. The slot content must be a <template> element. The content of the template should only be one <oj-c-line-chart-item> element. See the oj-c-line-chart-item doc for more details. A series-id and group-id must be specified.

When the template is executed for each item, 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 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:
Name Type Description
data D The data object of the current item.
index number The zero-based index of the current item.
key K The key of the current item.

seriesTemplate

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

When the template is executed for each series, 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 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.
