In the Style panel’s Analysis section, select Automatic wrapping from the Layout drop-down menu. The Analysis view will immediately wrap horizontally.
If you had been using a Linear layout and had already split the sequence portion of the view vertically, choosing Automatic wrapping will change vertical splits to horizontal ones. Also, the scroll bars will move from the bottom of the view to the right.
When the Analysis view is split, the Overview provides a separate “viewport indicator for each section. Splits are ignored when exporting an image, although the layout is preserved.
