After accessing data through data binding, the next step is to visualize it using a chart. The bound data is rendered using the open-source Apache ECharts library.
Hint
When you develop your custom widget, you can use any library or develop your own visualization.
Exercise
In this exercise, you will use the third-party Apache ECharts library to render data inside a custom widget.
You will:
- load a third-party visualization library,
- transform bound data into a chart-compatible structure
- render data as a line chart inside a custom widget.
Result
The custom widget displays data as a chart.
Summary
Custom widgets can use external libraries to visualize data beyond standard SAP Analytics Cloud capabilities.
Bound data must be transformed into the format required by the visualization library.
Rendering logic connects data binding with visual output, enabling dynamic and interactive charts.
