This article explains how to embed an SAP Fiori chart in an app in such a way that it has the correct size and scrolling behavior.
Vertically-Scrolled Page vs. Frame
The optimal way to embed a chart component in an app depends on the layout pattern of the app. Embedding a chart component in a split-screen layout is different from embedding one in a full screen layout.
Two main layout patterns must be considered:
In this layout pattern, the page scrolls vertically. If the page content cannot be seen in full, a vertical scroll bar appears.
In this layout pattern, the page contains multiple frames and does not scroll horizontally or vertically. If the page content cannot be seen in full, the frames are resized so that they remain visible. Some frames may remain with a fixed size, while other frames are resized. When a chart is embedded in a frame, the frame is generally resized.
Scrolling Direction of the Chart
How you embed a chart component in an app also depends on its scrolling direction. Embedding a chart that scrolls horizontally is different from embedding one that scrolls vertically.
For more information, see the article on the scrolling direction of charts.
As a design principle, you should avoid having two vertical scroll bars on the same page. To do so, try one of the following:
- Define the correct zoom setting to display the entire set of data.
- Make the chart non-zoomable, but ensure that the chart component is big enough to avoid having a vertical scroll bar inside it. The height of the chart component must be calculated so that its entire content can be seen without a scroll bar.
When the scroll bar of the page appears, the chart toolbar could disappear when scrolling. For that reason, this layout should be applied only for a small amount of data. For a large amount of data, it is better to embed the chart in a frame.
Embedding in Frames
In this layout pattern, the screen contains multiple frames and does not scroll horizontally or vertically. The scrolling is instead managed by each of the frames. When the chart component is embedded in a frame, it is resized to occupy the full height and width of the frame.
The chart component manages the scroll bars as necessary and displays the appropriate data point correctly.

Bidirectional Scrolled Chart
Charts that have no main scrolling direction should be managed on a case-by-case basis.
