Default view surface dimensions

Depends on monitor.

Resolution

The full view surface is 1024 x 1024 pixels.

Color capability

Color indices 0--255 are supported. The representation of all color indices can be changed. Define logical name PGPLOT_MONITOR = MONOCHROME to use a monochrome monitor: colors are then converted to shades of gray.

Input capability

The graphics cursor is a white cross-hair. The user positions the cursor using the arrow keys and PF1--PF4 keys on his terminal keyboard (SYS$COMMAND). The arrow keys move the cursor in the appropriate direction; the size of the step for each keystroke is controlled by the PF1--PF4 keys: PF1 = 1 pixel, PF2 = 4 pixels, PF3 = 16 pixels, PF4 = 64 pixels. The user indicates that the cursor has been positioned by typing any character other than an arrow or PF1--PF4 key [control characters, eg, ctrl-C, and other special characters should be avoided, as they may be intercepted by the operating system].
