NChart3D and NGrid are getting a pretty big update today which will bring new features for our chart and grid libraries. NChart3D now includes range selector, various improvements for surface series, and more. NGrid in its turn gets a custom sorting feature.

The newest NChart3D version delivers massive improvements for surface series. We have implemented the data smoother (as it is shown below), support of tooltips and improved rendering.

We have also improved the rendering for bubble series. Now the legend is displayed on the graph flawlessly.

The other major new feature in this update is the range selector. An image below shows how it works.

There are a number of other features within this release. We have separated the handling of chart and legend interactions. Furthermore, fixes for gradient brush scale were included in this release.

The newest update brings the API to switch point selection on/off in all supported series. If the feature is on, then there is a possibility to select points by tap. If the feature is off then the memory on internal structures can be saved.

Also since this release, the iOS and macOS samples have been migrated to the Automatic Reference Counting.
