Visualization and Analytics

WebFOCUS Designer allows you to integrate real-time streaming data with your charts using the Automatic refresh option. For example, if you configured a connection to a streaming data source using the Kafka adapter, the Automatic refresh option can be enabled to update your chart dynamically at a specified interval (in seconds). Depending on your specific use case or requirements, you can configure multiple charts using the Automatic refresh option and add them to a page, portal, or workbook. Each chart will refresh independently with updated data based on the specified refresh rate.

This topic describes how you can develop and enhance interactive content that has enabled In-Document Analytics capabilities.

Interactive Reports

 As a developer, you can create effective, useful reports and share them easily using In-Document Analytics for offline analysis.

HTML5 chart output is normally rendered in the browser, making it highly interactive. However, in prior releases, this type of output could not be generated in other formats, such as .png or .pdf. When customers wanted to generate chart output in a static format, they had to use the legacy graph API engine, which does not support the new features available with HTML5 charts, such as maps and other chart extensions.

You can use In-Document Analytics technology on a mobile device, including various types of phones and tablets. This enables you to review content, offline, that is shared with you by a developer or other similar individual within your organization. You can review your data anywhere, anytime.

Mobile devices support various gestures, including swipe and drag. In-Document Analytics supports the following standard interactive gestures for multi-touch screens:

You can access the Chart Rollup Tool from the column menu in an interactive report that uses In-Document Analytics. There are three tabs: Chart, Rollup, and Pivot.  As you create charts, rollups, or pivot tables, each artifact displays in the analysis panel.

You can use the Chart Rollup Tool to select multiple group fields to generate the chart, rollup or pivot table. 

For the Chart tab, you can select a chart type, an aggregation, and a column for the chart, as shown in the following image.
 

If you are working with a chart using the Chart Rollup Tool and you subsequently create a new chart, the new chart launches with a metadata tree, buckets, and the chart picker. This look and feel is similar to the common interface of WebFOCUS Designer, as shown in the following image.

The interface loads with the fields that you had originally selected. This makes it easy to select different fields to create different types of charts at run time.

When you run interactive content in maximized (full-screen) mode, there are a number of navigational features that you can use. For example, you can change the position of report and chart components in full-screen mode using drag and drop. To drag and drop, simply click the toolbar of any component and, holding the mouse, drag the object to the desired position.
