You can use transient views to quickly and conveniently display a complementary view of your data. Right click in a portion of selected data and choose “Transient Views”. Select the view that you would like. For example, choose FFT to display the spectral content of the data portion you selected.
You will get a new window containing the transient view; this window will have a dedicated toolbar. When you move this window through time, the transient view automatically adapts to the new content. Remember that this output is “transient”, i.e. it is not stored anywhere and no new node is created.
