Video: Adding user-interaction with drill-down/detail content from a database to a Google Chart web application (3/3)
Monday, May 6, 2019
The video series has taught us how to build a custom web service to deliver data to the web application showing a Google Chart. Displaying information is wonderful, but the chart shows only aggregated values. Any user of the application will have the desire to drill down into the data and not just see the sums and averages.That is why this video will show you how to add user-interaction and query the database to show specific information:
You will learn how to:
- Add interaction to your chart
- Add a pop-up window that displays drill-down information, also requested from the web service
- Specify XData Query operations
Here is a link to the video:
