The chart toolbar acts as a container for charts.

The width and height of the chart container are never defined by the app, but are always set by the container itself (as explained in Size of the Chart Container).

The toolbar is mandatory. Small charts or micro charts, such as dashboards, table cells, and small frames are an exception to this rule. In these cases, the developer must provide a consistent UI to enable action on the chart.

The toolbar is always placed on top of the chart. It provides actions such as multiple box selection for selecting dimensions, full screen format, personalization actions, and a toggle function for showing and hiding legends.

Responsiveness

The chart container uses the sap.m.OverflowToolbar control. It is a container based on sap.m.Toolbar that provides overflow when its content does not fit in the visible area. For more information, please refer to the toolbar overview article (under Responsiveness).

Components

Behavior and Interaction

Business Actions (app-specific)

Title

A title provides a short, meaningful summary of the content, often in a single word. To display a title, use the title control.

Use a title if you need the chart toolbar, and if the title of the chart is not indicated in the surrounding area. Note that the title is truncated if there is not enough space.

Variant Management

In charts, a variant stores all the settings that define the chart view (for example, the selected dimensions and the sort and filter settings). The variant management control enables users to load, save, and change variants. In most cases, variant management replaces the title.

Title and Variant Management

If you need both a title and variant management, place the variant management control directly after the title. Use a separator between the title and variant management.

Since using both controls often leads to truncation problems, this pattern is not recommended.

Perspective Switch

The perspective switch is left-aligned in the toolbar. It can be used to switch between different dimensions. We recommend using a select control, but any other dropdown control can be used as well. The perspective switch replaces the title and the variant management control.

For SAP Smart Business apps, the view incorporates and defines the chart description, the dimension, the measure, and the defaulted chart type. The various views are preconfigured and maintained by an SAP Smart Business administrator.

Ensure that all switches have a meaningful title. We recommend using a short chart description followed by the dimensions:

You also have the option of extending the perspective switch if the app needs to switch between specific subdimensions. The number of dimensions and subdimensions that are needed depends on the app.

If the app does not need a perspective switch, use the chart title (property: title).

Legend (Generic)

The Legend button (property: ShowLegend) is the first generic action. The user clicks this button to hide or show the chart legend.

The legend also allows the user to select or deselect data points.

Zoom In/Zoom Out

We recommend offering the zoom feature on the chart toolbar. Two icon buttons depicting a magnifying glass are then displayed. When the user clicks the Zoom In or Zoom Out button, the chart zooms accordingly.

Settings

You can add a Settings button to the chart toolbar to enable app-specific settings (property: ShowPersonalization). The corresponding popover or dialog must also be implemented by the app team.

We do not recommend using this feature. If you do choose to use it, exercise caution. Bear in mind that the perspective switch feature already allows preconfiguration of several combinations of dimensions, measures, and chart type selections.

When viewing charts, users do not usually want to think about which chart types, dimensions, or measures are most suitable in a particular use case. Instead, decide on the most valuable chart/dataset combinations for the end user beforehand and provide users with the most appropriate preconfigured chart view.

View Switch (Generic)

View Switch – Switch Between Chart and Table

The view switch allows you to switch easily between tables and charts.

Some actions are only available in certain views. For example, the Legend icon is only visible in the chart view. If the user selects the table view, the Filter action is visible and the Legend icon is hidden.

Icon Usage

Each visualization of a chart is represented by an icon. The icon explorer helps you to find the most appropriate icon.

Maximize / Minimize

In addition to zooming, the app can use the full screen mode of the chart container (property: FullScreen).

The user can open the chart in a full screen dialog via this toggle button. When the chart is maximized, the    Maximize button is replaced by a corresponding    Minimize button.

Overflow (Generic)

See Overflow in the Toolbar Overview article.

Guidelines

See the detailed Guidelines section in the Toolbar Overview article.

Additional Guidelines

• Think carefully about what actions you really need in the chart toolbar – do not overload the toolbar with actions.
• Try to put the actions as close to the content as possible.
• Use appropriate tooltips to label icon buttons in the chart toolbar.
