ParaView has the following list of chart related representations that are based on the vtkChartRepresentation class and its subclasses.
In this work, the necessary code changes have been implemented to support Partitioned Dataset Collection with Partitioned Dataset, as well as Multi-block Dataset with Multi-Piece Dataset. A notable UI update is the relocation of the CompositeDataSetIndex control to the Multiblock Inspector. This change was made to enable block selection for Partitioned Dataset Collection and to unify the block selection workflow across the Render View and Spreadsheet View. The CompositeDataSetIndex property has been replaced by the Assembly and Block Selectors properties, with backward compatibility maintained.
Additionally, for Partitioned Dataset Collection and Multi-block Dataset datasets, chart representations can now display all selected blocks (as chosen in the Multiblock Inspector) as a single chart entity—such as a line or box plot—rather than generating a separate entity for each block. This behavior is controlled by the new Array Selection Mode property, which can be set to Merged Blocks (new default) or Individual Blocks (previous behavior). With this improvement, users no longer need to manually select every block and enable each block array individually — a process that was especially cumbersome when working with hundreds or thousands of blocks, each containing multiple arrays.
