## A.4 Plot Windows

This section describes the plotting windows introduced at TOPCAT version 4. These provide most of the same functionality as the old-style plot windows, but additionally much more flexibility, configurability, extensibility and better performance and capabilities for making visual sense of very large data sets.

TOPCAT has a number of windows for performing data visualisation of various kinds. These share various characteristics which are described in the first subsection below; the specific windows themselves are described in the later subsections.

Seven plot windows are currently available:

- Histogram Plot
- Plane Plot
- Sky Plot
- Cube Plot
- Sphere Plot
- Corner Plot
- Time Plot

More may be introduced in future releases.

The rest of this section describes the plotting functions in detail.
