Project: QGIS
Version: 3.0.0
New symbol renderer that groups nearby points into a single rendered marker symbol. Optionally, a label displays the number of features that have been aggregated into the single symbol.
Additionally, some improvements have been made to the point displacement renderer, specifically:
- points are now assigned to the group which is "nearest" them, rather then just assigning them first group within the search distance. In some cases this was assigning features to a more distant cluster, resulting in less predictable cluster patterns
- individual points are now correctly shown in their own selection state
- lots of code cleanup + documentation too.
For developers: QgsPointDisplacementRenderer has been split into a new pure virtual QgsPointDistanceRenderer base class which handles the detection of clusters and grouping of points. The new cluster renderer reuses this base class to avoid code duplication.
