cpd: set current plotting device
Syntax: cpd < plot device>
cpd <filename>
cpd <filename>/{ps,cps,vps,vcps}
cpd none
Set current plot device. The same can be achieved with the
setplot device
command, which takes the same options. In the initial release of XSPEC12, as in previous versions, the plot device options are those allowed by the PGPLOT library.
If the second argument does not start with a ‘/’ character, which indicates that the string represents a PGPLOT device, it is taken to be a filename for Postscript output, and the default postscript driver will be used. The default postscript driver produces a monochrome plot in landscape orientation.
The filename argument can be followed by a ‘/’ that specifies a particular postscript driver variant. Allowable variants are: cps (color postscript), vps (monochrome portrait orientation), and vcps (color portrait orientation), as well as the default, ps.
cpd none
PGPLOT devices
A number of plot device types are supported in XSPEC. PGPLOT devices available on Unix machines are :
|
/GIF |
Graphics Interchange Format file, landscape orientation |
|
/VGIF |
Graphics Interchange Format file, portrait orientation |
|
/NULL |
Null device, no output |
|
/PPM |
Portable Pixel Map file, landscape orientation |
|
/VPPM |
Portable Pixel Map file, portrait orientation |
|
/PS |
PostScript file, landscape orientation |
|
/VPS |
PostScript file, portrait orientation |
|
/CPS |
Colour PostScript file, landscape orientation |
|
/VCPS |
Colour PostScript file, portrait orientation |
|
/TEK4010 |
Tektronix 4010 terminal |
|
/GF |
GraphOn Tek terminal emulator |
|
/RETRO |
Retrographics VT640 Tek emulator |
|
/GTERM |
Color gterm terminal emulator |
|
/XTERM |
XTERM Tek terminal emulator |
|
/ZSTEM |
ZSTEM Tek terminal emulator |
|
/V603 |
Visual 603 terminal |
|
/KRM3 |
Kermit 3 IBM-PC terminal emulator |
|
/TK4100 |
Tektronix 4100 terminals |
|
/VT125DEC |
VT125 and other REGIS terminals |
|
/XDISP |
pgdisp or figdisp server |
|
/XWINDOW |
X window window@node:display.screen/xw |
|
/XSERVE |
An /XWINDOW window that persists for re-use |
Closes the device. For Postscript output, it flushes the write buffer into the file and closes the file.
Note that in XSPEC12, each plot command produces a separate page in the postscript file, unlike previously where each plot overwrote the previous plot.
Example:
// produce a set of color postscript plots in landscape orientation
// … commands to produce a plot.
XSPEC12> cpd dataplot.ps/cps
XSPEC12> plot data chi
XSPEC12> plot ufspec
XSPEC12> plot efficiency
XSPEC12> cpd none
Will produce 3 plots in the file dataplot.ps.
Note, in contrast, that the hardcopy command will print only the plot that is currently in a graphics frame.
