UI Widgets

New Floating Button Widget

Pivot Grid

Remote Data Paging

Our PivotGrid’s data layer can now request the data it needs for an individual page. Remote data paging improves performance against large volumes of aggregated data.

PivotGrid - Cascade Filtering

Our PivotGrid can now apply parent field filters. For instance, if you filter the PivotGrid by the 'Country' field, the 'City' field's filter items will also be filtered against the same Country.

Scheduler

Adaptivity and UX Enhancements

We have improved Scheduler usability on mobile devices. In v19.1, the Scheduler control renders a popup appointment list instead of a tooltip. The appointment list is displayed in full screen mode.

The appointment edit form is also rendered in full-screen mode on mobile devices.

In addition, larger appointment markers are now used on mobile devices.

    We added a 'legend.customizeItems' callback so you can change the order, text, and visibility of legend items.

    Documentation Demo

  • Legend Title

    A legend title can now be specified and configured using the 'legend.title' option. You can customize the title's appearance and its position, and add a subtitle as well. This new option offers the same capabilities as the widget's root title option.

Resolve Label Overlaps

The resolveLabelOverlapping option allows you to specify widget behavior when labels overlap one another.

  • Resolve Label Overlaps within a Funnel Chart

    In the Funnel, this option accepts 'shift' (default), 'hide' and 'none.' If no room exists to display all labels after a shift, the algorithm hides labels as needed.
