Results of MP decompositions stored offline ("books") can be visualized as interactive time-frequency maps of signals energy density. This can be achieved either by clicking "open in the viewer" in the "get result" window, which appears after a successfull MP decomposition, or expliciltly opening a previously computed book via File -> Open book or Alt+B. Both these actions open a new tab.

The center of the tab is occupied by the time-frequency map of signals energy density, calculated as a sum of Wigner distributions of all the functions chosen by MP for the representation of given signal. The map itself is interactive -- centers of the atoms are clickable.

Below the interactive map three signals are displayed with time scale aligned with the map. These signals are, from the top: the original signal, its reconstruction from all the atoms in the book (the difference between these two stems from the fact that MP is an approximation), and in the bottom the signal reconstructed from all the selected atoms -- initially flat. To add an atom to (or remove from) the reconstruction simply click it's center on the time-frequency map.

Functionalities related to the interactive display are accesible from the toolbar at the top. The group located on the left contains, from the left:
