1.1.5. - Graphics
For high-resolution graphics, C-PLOT produces
a device-independent output stream that is directed through device-dependent
filter programs.
The C-PLOT package includes
filter programs for many popular graphics terminals, laser printers
and other output devices; if a graphics filter doesn't exist already
for your graphics device, it is relatively simple to build one by
adapting the existing C-language modules and libraries included in
the plotting package.
Apart from the filter output stream is C-PLOT's
bidirectional communication with an
HP-GL
plotter over a serial
or
GPIB
interface.
You can set the size and position of the
plot axis and the position of plot annotations through the program
or with the plotter's front-panel controls.
C-PLOT's fast PseudoGraphics will work on almost
any video terminal that can run a UNIX visual editor.
You can
use PseudoGraphics, for example, to view the trend or scaling of your
plot before sending it out to a high-resolution device.
PseudoGraphics
can be used with C-PLOT's data editor to delete,
insert and modify points as they are displayed on the video screen.
