‘Save snapshot’ will take the current vectorscope data and write it to a named bitmap file.
On the Window menu are controls to resize the vectorscope display to match the resolution in which it is being generated. These work in a similar fashion to these controls on the waveform window.
Region of Interest Window
The Region of Interest window controls some of the less required function, as most of the controls can be achieved by other means. Alternative ways of control will be described along with the functions on this window. These controls are global in that they affect the portion of the video image that is used to create the waveforms, the vectorscope, and the histograms. Note that the dataview display is unaffected by these controls, as it always shows the exact incoming data based around the current cursor position.
The top control is the most important one, and lets you change the waveform view from all lines (multi), to single line, or to sweep mode. This control is available by clicking on
the line mode button 
on the main toolbar.
The horizontal and vertical controls let you narrow down the area of interest.
