ActiveReports v3.1 brings several enhancements that improve the product experience for developers, report authors, and end-users of your application.
ActiveReportsJS runs and renders reports on the client-side in the browser. There are multiple stages of report rendering – data processing, layout building, and drawing. Data processing could be a heavy task if using a large data set because it involves reading, parsing, and transforming operations. ActiveReportsJS now processes the data in the background thread using Web Workers technology. In practice, this means that the page in the browser does not freeze when a report is bound to a large dataset. It significantly improves the user experience. Here is an example of a report that shows 50,000 records.
The PDF Export now allows generating PDF/A-compliant documents. You could set the PDF/A-2b and PDF/A-3b compliance levels by using the Version property of the PDF Settings in the UI or API calls.
The brand new Layers Editor UI allows you to create and manage report layers. This feature could be useful to vary the report output based on the target device – viewer, export, or printed document. Read more information on the Report Layers page.
You can now supply a chart with reference lines, reference bands, and trendlines, including regressions lines and moving averages. Read more information on the Overlays page.
