At version 4, TOPCAT introduces a new set of plotting windows. These provide most of the same functionality as the classic plot windows, but additionally much more flexibility, configurability, extensibility and better capabilities for making visual sense of very large data sets.
In their initial release v4.0b these windows are considered experimental. To access them, use the Graphics menu in the main Control Window. In future releases the capabilities will be extended, the details of the user interface may change following user feedback, and they will be made more prominent in the main window, possibly replacing the classic plot windows.
Four layer plot windows are currently available:
More may be introduced in future releases.The rest of this section describes the layer plot functions in detail.
