Graphics
Instrument BASIC adds graphics capability to the analyzer. You can draw pictures on the LCD
display independent of the grids and traces.
The analyzer has two screens, the instrument screen and the graphics screen. These two
screens are always displayed together on the LCD and are not separately selectable. The
instrument screen consists of a trace display area and a softkey label area. The Instrument
BASIC editor is also displayed on the trace display area. The graphics screen covers the
entire instrument screen as shown in Figure 7-1. The graphics screen is like an independent
transparent overlay in front of the instrument screen. Therefore, you can draw gures in both
the trace display and softkey label areas.
