Zooming and Moving Graphs
Once you have acquired data, you can use zoom and pan functions on the
graphs to better see the results. The Zoom and Pan buttons are located on
the right side of the main window.

When modifying the zoom level of a pattern diagram, or if you move its
view area, all pattern diagrams for the same polarization will adjust to
this new zoom level. This allows inter-graph validation and analysis.

Constellation graphs are always zoomed isotropically (same zoom
level on both axes) to keep their square appearance.
